Senior Product Designer, AI-Native
Senior • Remote
15,000 - 30,000 PLN
About the role
Rimthan is a corporate venture builder operating across Saudi Arabia and the GCC. We launch ventures with regional partners and act as the product, design, and engineering muscle behind them. We are looking for a Senior Product Designer who is genuinely AI-native, an expert prototyper, and obsessed with execution. You will own the design surface of one of our ventures, working hand in hand with venture building, product management, engineering, and UX research, and you will use AI to compress the distance between idea and working software to days, not weeks.
This is a role for someone comfortable being uncomfortable. The pace is fast, the environment is hands-on, and we expect you to get shit done. Reports to our Chief Product and Design Officer, Marcus Wiberg.
What you will do
-
Own the craft. Take a problem from fuzzy ask to shipped, polished experience. You define the visual and interaction direction, the bar for quality, and what good looks like end to end.
Prototype, fast. Stand up working, interactive prototypes in hours using Figma, Figma Make, Claude, Cursor, v0, Lovable, Replit, and whatever comes next. Bring something testable to every conversation, not static screens.
Design systems and patterns. Build and evolve the design language for your venture. Make it scalable, opinionated, and consistent, without slowing the team down.
Spend your time on the right things. Use agentic workflows to automate the work that does not need you (asset production, redlines, design QA, component variants, copy iterations) so you can spend most of your time on the hard creative and product problems.
Partner on discovery. Work with UX research and product to talk to users weekly, validate flows, and keep the team honest about what is working and what is not.
Communicate and align. Drive clarity across venture building, engineering, product, research, leadership, and partners. Strong written and verbal communication is non-negotiable.
Ship. Push designs to production with engineering, hold the quality bar through release, and iterate on what users actually do.
Who you are
5 to 8 years in product design, with a track record of shipping products real users use.
Strong visual and interaction craft. Your work holds up next to the best in the industry, and you can explain why every decision is the way it is.
Expert at vibe coding. You can put a working, coded prototype in front of a user without waiting for an engineer.
Deep, hands-on user of Claude. You have pushed the tool well past chat: chained tools, MCP integrations, custom agents, evals, or workflows that do real work for you and your team.
Fluent in modern design tools. Figma to a senior level, Figma Make, and AI-powered design and prototyping tools as part of your daily flow.
Strong communicator. You make complex things clear, fast, in writing and in the room.
Strong collaborator across disciplines. You partner naturally with venture builders, product managers, engineers, and researchers, and you know how to get the best out of each.
Entrepreneurial and creative under constraint. You take ownership without being asked, you finish things, and you find the path others miss when time or scope is tight.
Hands-on by default. You execute, you get shit done, and you thrive in fast-paced ambiguity.
Excellent written and verbal English.
Big pluses
Previous experience working in the GCC. You understand the regional market dynamics, cultural nuances, and business landscape in Saudi Arabia and the wider Gulf.
Arabic. Useful given where we operate, optional otherwise. Bonus if you have shipped RTL interfaces and understand the typographic and layout considerations that come with it.
Founder or entrepreneur background. You have started something of your own, run it, and lived with the consequences. You know what it feels like to own a problem end to end.
Software house, consultancy, or agency experience. You already know how to context-switch across clients, ship under fixed timelines, and deliver work that holds up to outside scrutiny.
Engineering or product background. Not required, but a massive advantage. If you can pair with engineers as a peer on technical decisions, or step into PM-shaped problems when needed, we want to hear from you.
What we offer
Real ownership of a product line inside a venture being built and scaled in real time.
A team that already operates as AI-native. No fight to use Claude, Cursor, or new tools as they emerge.
Direct access to executives at Rimthan and our partner organisations. Decisions happen fast.
Competitive compensation and a high-trust, low-bureaucracy environment.
20 days of paid time off, including some recognised public holidays.
Travel may occasionally be required. It is rare, and we cover flights and accommodation when it happens.

Krakow, Poland
22,000 - 30,000 PLN
🏢 Summary: Senior hands-on DevOps/Platform Engineer role owning a multi-cloud, multi-region Kubernetes platform across GCP and OCI. The position focuses on architecting GitOps delivery pipelines, strengthening security and secrets management, and ensuring high availability, observability, and disaster recovery. You will codify infrastructure as code and enhance developer experience through automation and self-service platform capabilities. 🗂️ Requirements: Strong production experience with Kubernetes at scale, Proven expertise in Terraform and Infrastructure as Code practices, Hands-on experience with GitOps using ArgoCD or equivalent, Experience implementing progressive delivery patterns, Solid experience with secrets management and identity systems, Experience operating managed PostgreSQL and Redis in production, Practical experience with observability and monitoring stacks, Ability to manage multi-cloud environments, Experience designing and testing disaster recovery and failover setups, Strong security-focused operational mindset 📃 Skills: Kubernetes, Terraform, Helm, Kustomize, ArgoCD, ArgoRollouts, GitHubActions, Istio, Vault, Keycloak, ESO, PostgreSQL, Redis, Grafana, Loki, Tempo, Mimir, GCP, OCI 🏢 Description: Senior DevOps / Platform Engineer Rimthan — AI Venture Builder Remote · Distributed team (Europe + KSA) About Rimthan Rimthan is a Saudi-based AI venture builder. We design, build, and operate AI products end to end. We run a lean, distributed engineering team that ships fast and favours self-hosted, open-source tooling we control over opaque SaaS. We're building serious infrastructure for the Kingdom and beyond, and we need a platform engineer who treats reliability, security, and developer experience as first-class products. The Role You'll join the platform team that owns the infrastructure our products run on: a multi-cloud, multi-region Kubernetes estate spanning GCP (Dammam) and OCI (Jeddah). This is a hands-on senior role — you'll architect the GitOps and delivery pipelines, harden our service mesh and secrets posture, and make sure the developers building on top of your work barely have to think about infrastructure. You won't be a one-person army: you'll work alongside other platform and application engineers, sharing ownership and on-call rather than carrying it all alone. If you like owning systems rather than tickets, and you want a stack with no legacy baggage, this is for you. What You'll Work On Multi-cloud, multi-region: GCP and OCI across a multi-project layout, including a credible, tested failover story between the two. Infrastructure as Code: Terraform for cloud resources; Helm and Kustomize for Kubernetes workloads. Everything reproducible, reviewed, and versioned. Orchestration: Kubernetes across both clouds — Helm-packaged workloads, HPA-driven autoscaling, sensible resource and capacity management. Service mesh: Istio for traffic management, mTLS, and observability at the network layer. GitOps & progressive delivery: ArgoCD as the source of truth for cluster state, Argo Rollouts for canary and blue-green deploys, GitHub Actions for CI. Secrets & identity: HashiCorp Vault as the secrets backbone, External Secrets Operator to sync into clusters, and Keycloak for SSO and identity across our services. Data platform: Cloud SQL for PostgreSQL 17/18 and Memorystore for Redis 7, supporting application teams who use Drizzle ORM with a forward-only migration discipline. Observability: The full Grafana LGTM stack (Loki, Grafana, Tempo, Mimir) for logs, dashboards, traces, and metrics. Responsibilities Design and operate the production and DR Kubernetes platform, owning availability, scaling, and the GCP→OCI failover path. Build and maintain GitOps delivery pipelines that let teams ship safely with progressive rollout and fast rollback. Manage the secrets and identity layer (Vault, ESO, Keycloak) and keep our security posture tight across both clouds. Codify all infrastructure in Terraform/Helm/Kustomize and drive consistency across projects and environments. Run the observability stack and turn signals into actionable alerts and SLOs — not dashboard noise. Partner with application engineers on the data layer: connection management, performance, and a clean forward-only migration workflow. Improve developer experience: reduce toil, automate onboarding, and make the platform self-service where it makes sense. What You Bring Must have Strong production experience operating Kubernetes at scale, including Helm and autoscaling. Deep Terraform skills and a real IaC discipline. Hands-on GitOps experience with ArgoCD (or equivalent) and progressive delivery patterns. Solid grounding in secrets management and identity — Vault, ESO, Keycloak or comparable tools. Experience with managed PostgreSQL and Redis and the operational concerns around them. Practical experience with observability , ideally the Grafana ecosystem (Loki/Tempo/Mimir/Grafana). A security-first mindset and comfort owning incidents end to end. Nice to have Multi-cloud experience, especially GCP and OCI together. Hands-on Istio or another service mesh in production. Experience designing and testing DR / failover across regions or clouds. Familiarity with Argo Rollouts specifically. Background supporting AI/ML or agentic workloads in production. Comfort working in a distributed, async, fast-moving team. How We Work Remote-first and distributed across European and KSA time zones — we expect meaningful overlap with the team's core hours. Open-source and self-hosted by default; you'll have real ownership of the tools you run. High autonomy, low bureaucracy, and a stack you can shape rather than inherit. Apply If this sounds like your kind of problem, reach out with your CV or profile and a few lines on a platform you've built or rescued. We'd love to hear from you.

🏢 Summary: Lead UI/UX Designer role owning end-to-end product design, visual language, and design system for a learning and research product. You will turn ambiguous problems into clear UX flows and high-fidelity UI, collaborating closely with engineering to ship polished experiences. The role combines product design, brand identity, and rapid user validation with full ownership of quality and craft. 🗂️ Requirements: Proven experience in end-to-end UI/UX design for digital products, Ability to create UX flows, wireframes, prototypes, and high-fidelity UI, Experience defining and scaling design systems with components and variants, Proficiency in Figma for auto-layout, prototyping, and system management, Experience collaborating closely with engineering for production handoff, Ability to conduct lightweight user research and rapid validation, Strong understanding of HCI principles and interaction design, Ability to define and maintain cohesive brand identity across product surfaces 📃 Skills: Figma, UX, UI, Prototyping, Wireframing, DesignSystems, Typography, Illustration, Branding, HCI, InteractionDesign, AutoLayout, UserResearch 🏢 Description: ABOUT THE ROLE We're looking for an expert UI/UX designer with outstanding taste and a bias for shipping to lead every visual and brand aspect of our product — from the core design system down to the last pixel. This is not a "pure artist" role. You'll work in a tight product team, iterate fast, and make hard trade-offs when reality demands it. You'll own the visual language of a product used by people who care deeply about learning and research. The expectation is high — you define what good looks like, and you hold that bar as the product grows. WHAT YOU'LL WORK ON Core product journeys Own end-to-end design for the most important product experiences — search and discovery, reading, notes, and collaboration. Turn ambiguous problems into clear UX flows, prototypes, and shippable UI. Design system Define and evolve the design system — components, variants, states — so the team can move fast without quality regressions as features multiply. Craft and details Raise the bar on hierarchy, interaction, motion, and micro-details so the product feels inevitable rather than assembled. Engineering collaboration Work in a tight shipping loop with engineering to land high-fidelity designs in production exactly as intended. User research Run lightweight user research and rapid validation when it meaningfully reduces risk — not as a process, but as a tool. Brand coherence Keep brand and marketing surfaces coherent with the product — visual language, typography, and key visuals. WHAT WE LOOK FOR Elite communication You set expectations accurately and live up to them. No surprises on timelines, scope, or quality. Deep resilience Feedback cycles, tight deadlines, tough discussions — you have a large buffer before stress impacts your output. No ego Your work gets better through collaboration. We're here to build something great, not to manage insecurities. Product mastery You understand what makes great software feel inevitable — clarity, hierarchy, consistency, motion, copy, and details. You've studied the best and can articulate why it works. Brand instinct You can define a visual identity that feels premium, coherent, and distinctly ours — and keep it consistent as the product scales. HCI fascination Deeply interested in human-computer interaction. Actively exploring AI-native interfaces and new interaction primitives that feel intuitive, not bolted on. Bonus Ex-founder experience. DESIGN STACK Figma for components, variants, auto-layout, prototyping, and design systems. Brand identity, guidelines, typography, colour, and illustration. Close collaboration with engineering for production handoff. Lightweight user research and validation. The stack isn't fixed — outcomes matter more than tools. DESIGN CULTURE Radical ownership You own the visual language and the bar. You decide what good looks like — and you're accountable for it. Ruthless simplicity We delete, simplify, and reduce. Every element must earn its place. Fast iteration Polished does not mean slow. We prototype, test, and refine quickly. Direct feedback Feedback is blunt, concise, and respectful. No politics. RECRUITMENT PROCESS Recruiter screening — a short intro call. 1-on-1 with the founder — a conversation about how you think and design. Design challenge (~2 hours) — onboard to the product, review what's working and what isn't, record a Loom and send it over. COMPENSATION & BENEFITS Salary $90,000 – $120,000 depending on experience. Equity and profit share Core team members receive both equity and profit share as part of the compensation package. Unlimited PTO Use your own judgement — we won't count days. Real ownership No managers capping your authority. You own your work end-to-end, with the full trust of the team behind you.

🏢 Summary: UX/UI Designer role focused on designing scalable, AI-ready mobile products using advanced Figma workflows and robust Design Systems. The position involves end-to-end UX process ownership, from service design and workshops to interactive prototypes and collaboration with Scrum teams. Emphasis is placed on accessibility, WCAG compliance, and delivering implementation-ready designs. 🗂️ Requirements: 3+ years experience as UX/UI Designer in mobile apps, Proficiency in Figma, Experience building and maintaining Design Systems, Experience working in Scrum, Ability to create Low-Fi and Hi-Fi interactive prototypes, Knowledge and practical application of WCAG standards, Experience with Service Design methods, Fluent English, Polish language required 📃 Skills: Figma, Flutter, WCAG, Scrum, ServiceDesign, DesignSystems, Prototyping, MVP, LeanStartup, Benchmarking 🏢 Description: Hello UX/UI Designer About LeanCode At LeanCode, we build core technology solutions for global, large-scale organizations. We are a global leader in Flutter , an official Flutter Consultancy, and one of only four agencies at the Flutter Advisory Board – working closely with Google and delivering projects worldwide: from the US and LatAm, through Europe (UK, DACH, Nordics), to Australia. At our core, we are a team of 75+ engineers, designers, and specialists, who learn fast, constantly improve, and never cheat – both in how we build software and how we work with our clients. 2026 is all about AI. Yet design might be the very last domain to be entirely replaced by autonomous agents. That’s why your role as a designer is more important than ever: to embrace the superpowers AI provides, while still driving the creative process yourself. At LeanCode, we’re looking for a UX/UI Designer who wants to: Master the tools needed to build AI-ready projects with Figma MCP; Create and evolve complex Design Systems that scale; Take ownership of the usability of mobile products, ensuring a user-centered approach in every feature; Grow in a stable environment that values both great project delivery and your personal development. Ensure all designs follow WCAG standards to create inclusive digital products. If this sounds like you, then you might be the perfect fit for the UX Designer role at LeanCode! Craftsmanship first In our projects, we push Figma to its limits by building beautiful, programmable Design Systems. We maintain our own LeanCode Design System and adapt it for each project to ensure efficiency and consistency. Our UX team works hand in hand with developers, making sure every detail is covered — from interactions and animations to edge cases — so that designs are both exhaustive and implementation-ready . UX goes beyond mockups When working with our clients, we rely heavily on Service Design techniques to uncover the real pain points end-users face and craft solutions that truly address their needs. We are strong advocates of the Lean Startup approach (as described by Eric Ries), which pushes teams to step outside the office, validate business needs with clients, and run interviews with end-users. Our design process typically begins with interactive workshops lasting two to four weeks (inspired by Jake Knapp’s Google Sprint guidelines). These sessions often result in a Proof of Concept .

🏢 Summary: Senior Full Stack Engineer role with end-to-end ownership of user-facing product features across frontend and backend. The position focuses on turning vague product goals into shipped, production-ready solutions with strong product judgment, code quality, and performance. You will work across UI, APIs, and data flows while leveraging AI tools to accelerate development and improve engineering workflows. 🗂️ Requirements: Senior-level experience shipping production web applications, Strong frontend expertise with React and TypeScript or modern equivalent, Ability to design and implement APIs and backend logic, Experience building and maintaining data flows in production systems, Experience instrumenting applications for production monitoring, Ability to write and maintain automated tests, Experience using AI tools in daily development workflow, Strong understanding of performance and reliability in web applications 📃 Skills: React, TypeScript, JavaScript, Python, Node.js, APIs, REST, HTML, CSS, Testing, AI, Git 🏢 Description: About Shelf Shelf builds software that helps enterprises make AI work in the real world. We build products people depend on, which means product judgment, engineering quality, and execution speed all matter at the same time. About the Role This role is for a senior full stack engineer with strong product instincts. You will own meaningful product slices end to end: understand the problem, shape the approach, build the frontend and backend pieces, ship them, and improve them based on real usage. We want someone who is equally comfortable improving a user flow, shaping an API, and closing the loop on quality in production. This is a product engineering role with real end-to-end ownership. Location – Warsaw, work from the office What You Will Own Build and ship user-facing product features across frontend and backend boundaries. Turn rough product goals into practical solutions with good scope, sensible trade-offs, and strong execution. Work comfortably in UI, application logic, APIs, and data flows rather than stopping at team boundaries. Partner closely with product and design while still being able to move when the spec is incomplete. Improve usability, clarity, performance, and reliability, not just feature completeness. Instrument what you ship so we can learn from production behavior and iterate quickly. Use AI tools daily to move faster and help improve internal workflows, tooling, and engineering leverage. Keep the bar high on code quality, testing, and ownership after launch. What Strong Performance Looks Like You can take a vague product problem and turn it into a shipped, well-reasoned solution. Your features feel coherent end-to-end because you care about both implementation and product quality. You do not treat frontend and backend as separate worlds; you use both to solve the actual problem. You bring momentum. Work moves because you are on it. What We Are Looking For Strong senior-level experience shipping production web products. Strong frontend ability with React and TypeScript or an equivalent modern web stack. Real backend ability. You do not need to be backend-only, but you can design and ship APIs, backend logic, and data flows when the product needs it. Strong product sense. You notice awkward flows, weak defaults, and unnecessary complexity, and you improve them. Good judgment about scope, iteration, and technical trade-offs. Clear communication and comfort working across engineering, product, and design. AI-native working style. You already use AI tools as part of daily implementation and problem solving, and you are excited to improve how engineering work gets done. Strong Plus Experience with AI-powered product experiences such as chat, search, recommendations, workflows, or agent-like systems. Experience with Python, Node.js, or both on the backend. Experience owning product areas with limited oversight. Strong feel for performance, accessibility, and production quality in complex web applications. How We Evaluate Fit We care more about end-to-end ownership, product sense, and the ability to ship meaningful work than a perfect match to every framework on paper. If you are the kind of engineer who can make a product better from multiple angles, we want to talk. What Shelf Offers B2B contract. Stock options. MacBook Pro. A strong AI-native engineering environment with modern tools and room to experiment.
