🏢 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.
