Build the architecture for SINGU's newest revenue line — Project Tracker. The product Project Tracker is SINGU's new module for managing CAPEX/OPEX projects across commercial real estate portfolios. MVP went live early this year. Foundations work, but the architecture for the next few years is still open. Traction is real: 294 people from 110 clients on the waitlist (Prologis, Mapletree, NEPI, Globalworth, Segro). After a demo, Prologis's Director of Global Operations asked for early access. Separately priced module – a revenue line, not a free feature. Alongside Project Tracker, we have several AI initiatives in active development across the platform. As Tech Lead you won't be siloed in one module – you'll have visibility and a seat at the table on the broader AI work shaping where the product goes next. The team Small and co-located in our Kraków office: a PM, a UX designer, a backend developer, a fullstack developer, and a mobile developer, QA sits in a dedicated team alongside us. You'll work shoulder-to-shoulder on the same floor. The stack PHP 8 on Phalcon (monolith), PostgreSQL, React 18 in parts of the UI, TypeScript. What you'll do – honestly This isn't a pure tech role. You'll juggle: Architecture: decisions that stick for years on a module still finding its shape. Requirements analysis & work decomposition: turning client needs into shippable scope. Hands-on development: you ship code. People work: knowing when to call the shot and when to trust the team. What we're looking for: 5+ years commercial PHP (8+), confident with Git, PHPUnit, PHPStan, CSFixer. Fluent in PostgreSQL (schema, performance, migrations). Production React (TypeScript preferred). SOLID, design patterns, REST API design as second nature. You actively use AI tools (Copilot, ChatGPT, Claude) – expected, not nice-to-have. Tech Lead experience: either proven, or you've been making technical and architectural decisions as a senior and are ready to step into the role Polish fluent enough to work daily with the team. English good enough to run client meetings: our clients are a mix of Polish and international, so you'll switch between both depending on the call. Nice-to-haves: Flutter, AWS, Kubernetes/Docker/CI, experience with Phalcon or similar lightweight PHP frameworks. Honest notes Project Tracker is early – a new module still in active development. The MVP is live, but the product is taking shape and you're shaping its architecture, not inheriting it The role is a mix. Hands-on + architecture + analysis + people. If you want to stop coding, this isn't it. No on-call for this role. The practical stuff Salary: 20,000–25,000 PLN net B2B / 16,600–20,750 PLN gross UoP. Hybrid: 2–3 days/week from Kraków office. Top-notch Apple equipment , private healthcare (dental + vision), life and health insurance, sport card, annual training budget, commute subsidy, referral programme, extra day off for medical check-ups, annual team offsite.

Now we're rebuilding the user experience for the next 20 years, migrating from a legacy stack to a modern Blazor application – and growing a new engineering hub in Kraków to lead that work. What you'll do: Own end-to-end delivery: requirements → API → implementation → release. Work across the full stack: .NET (C#, ASP.NET , Web API, EF) and SQL Server (T-SQL, stored procedures, SSIS). Substantial backend work, not frontend-only. Lead the Blazor migration: architecture, components, performance, accessibility. Shape how the Polish hub works: code standards, patterns, ways of working. The team 3 developers in Kraków today, scaling to 6 (you'd be one of three new hires). 11 developers in Cyprus, plus Synbiotix domain experts in the UK with two decades of NHS experience. You'll report locally to an Engineering Manager and Team Lead in Poland. You'll thrive here if: You've shipped real production .NET systems ( C#, ASP.NET/Web API, EF, SQL Server ). You're confident across the stack and either know Blazor or are excited to go deep on it ( Angular/React/Vue background is fine). You enjoy migration work – untangling legacy, deciding what to preserve, shipping incrementally. You speak fluent English and Polish – English for daily work with Cyprus and the UK, Polish for the Kraków hub. You want ownership and influence over a codebase to disappear into. Honest notes: The legacy stack is mature – ASP.NET MVC, Web API, EF, jQuery, SSIS. That's why we're hiring seniors to lead the modernization. The Polish hub is new – meaningful influence on engineering practices, but you'll help build them, not inherit them. No formal on-call – occasional out-of-hours attention is rare, and putting proper processes in place is part of what this role can shape. The practical stuff: Salary: 20,000–24,000 PLN net B2B, or 16,600–19,900 PLN gross UoP. Hybrid: 2–3 days/week from our Kraków office. Top-notch Apple equipment , private healthcare (dental + vision), life and health insurance, sport card, annual training budget, commute subsidy, referral programme, extra day off for medical check-ups, annual team offsite.

As we continue to grow through strategic acquisitions and bold innovation, we stay true to our core values: adaptability, collaboration, and client focus . If you’re ready to help build Europe’s leading platform for property operations — and make a tangible impact on how the real estate industry works — join SINGU and be part of this transformation. About the role QA roles usually mean owning one product. Ours doesn't work that way. At SINGU, the QA team works across the entire product group . Any given month you might be setting up a new automation project from zero , going deep on an API regression suite , or prototyping something in security or performance . Our recent QA hires joined specifically because nothing else looked this open-ended. We're growing the team and hiring three Regular QA Engineers . What you'll do: Build and maintain automated tests across multiple SINGU products – web and API as the baseline, with optional depth in security, performance, accessibility, or mobile Set up new automation projects from scratch. You're not inheriting someone else's flaky suite Write tests in Playwright (TypeScript) and ship them through Jenkins / Bitbucket Pipelines Pick a specialization that fits your interest and run with it – there's real demand across the board Contribute to QA standards and practices across the group Your development path – partly your call, partly ours This is the part most of our recent hires said sold them on the role. Where you go deeper is a conversation: your interests on one side, what the business needs most at the moment on the other . We meet in the middle, and it actually works – people here have shifted focus as priorities and interests evolved. The directions we have real demand for: Security — ZAP, dynamic scanners, OWASP. We'd love one of the three hires to know this space or actively want to grow into it. Not a pentester role , but real security work in a QA context. Performance testing — open space to build this out. Accessibility — room to own it and shape how we approach it. Mobile — we already have two engineers focused on this, so mobile depth is welcome but not required. If it interests you, there's room to plug in. End-to-end and API automation — the bread and butter, and where most of the team's time goes. You'll thrive here if: You've shipped production test automation as a Regular QA Engineer You're hands-on with Playwright or Cypress in TypeScript You're comfortable with API testing (REST, HTTP, JSON) You want to write code, not click through manual scripts – this role is 100% automation You can run with autonomy and don't need someone scheduling your week You speak fluent Polish and English (B2/C1) – both used daily across the team and the wider group Nice to have: CI/CD pipeline experience (Jenkins, Bitbucket Pipelines, or similar) Security testing — OWASP Top 10, ZAP, dynamic scanners Track record of setting up automation projects from zero Agile / Scrum team experience Understanding of test environments and test data management Honest notes: The dev side has substantial legacy (PHP, .NET). That's part of why QA matters here — your automation is the safety net for refactoring and migration work happening in parallel. The QA stack itself is modern. The team is small and the structure is light . We move fast and expect you to figure things out. If you want a fully laid-out playbook, this isn't it. We hire on automation, but functional testing instinct still matters — you're testing real products used by real customers, not just writing scripts. What we offer: 💰 Competitive Salary Range – Depending on your experience, we offer between 15'000 - 18'500 PLN net on a B2B contract , or 12'500 – 15'400 PLN gross on Contract of Employment. 🤝 A fantastic, engaged, and experienced team – Collaborate with passionate people who love what they do. 🎯 An environment open to innovation – We embrace creativity and new ideas in a dynamic setting. 🏡 A family-like atmosphere with a "you" culture – in a company that values "we". 📚 Annual budget for training & education – Invest in yourself with a dedicated budget for learning & development—no need to take a day off, it’s included in your working hours! 🕘 Flexible working hours – Work the way that suits you best. 🩺 Private healthcare (including dental & vision care) – Your well-being is important to us 📆 Extra day off for medical check-ups – Because your health comes first 🌍 Annual team offsite – Spend time with the team in a beautiful location. 🍏 Top-notch Apple equipment – The best tools to do your best work. 🥐 Monthly themed breakfasts – Start your day with great food & company. 🎁 Referral Program – Get rewarded for bringing great people on board.

🏢 Summary: Senior fullstack (backend-heavy) engineer to build a greenfield prenatal screening diagnostics product, owning architecture and features end-to-end from backend to selected frontend components. The role focuses on designing scalable Java/Spring Boot services, APIs, and data models, while contributing to React/TypeScript UI and shaping technical direction in a fast-moving MVP phase. Strong emphasis on clean architecture, testing discipline, AWS deployment, PostgreSQL, and effective use of AI-assisted development tools. 🗂️ Requirements: Strong expertise in Java and Spring Boot, Clean API design and domain modeling, Experience defining service boundaries and scalable architectures, Solid understanding of OOP, SOLID, and clean architecture, Working proficiency in React and TypeScript, Proven use of AI coding tools in daily workflow, Experience writing unit, integration, and API tests, PostgreSQL schema design and query optimization, AWS production deployment experience (ECS/EKS, RDS, Lambda, S3), Ability to work in greenfield, ambiguous environments 📃 Skills: Java, Spring, SpringBoot, React, TypeScript, PostgreSQL, AWS, ECS, EKS, RDS, Lambda, S3, REST, OOP, SOLID, SQL, AI, Cursor, Claude 🏢 Description: We are building a new prenatal screening diagnostics product from scratch. The project is currently in an early greenfield phase, with MVP delivery planned within the next six months. We are looking for a senior engineer who enjoys building products end-to-end and feels comfortable taking ownership across the full development lifecycle — from backend architecture and data modeling to APIs and selected frontend features. This role is backend-heavy, but requires a pragmatic fullstack mindset and the ability to contribute wherever needed. You will work closely with product stakeholders in a fast-moving environment, helping shape both technical direction and product decisions. We are particularly interested in engineers who actively use AI-assisted development tools (such as Cursor, Claude Code, or similar) as part of their daily workflow and understand how to leverage them effectively while maintaining high engineering standards and code quality. You will have a direct impact on: defining system architecture and service boundaries, designing scalable backend solutions, building APIs and core business logic, contributing to React/TypeScript frontend development, establishing engineering best practices, testing strategy, and maintainable code standards. The project operates in the diagnostics domain, so attention to quality, reliability, and clean engineering practices is essential. Requirements: Strong Java and Spring Boot expertise — clean API design, domain modeling, sound architectural trade-offs. You think in terms of service boundaries, data flow, and maintainability, not just making it work Solid grasp of software design principles — object-oriented programming, SOLID, clean architecture, separation of concerns. You write code that the next person can read, extend, and trust. You know when a pattern helps and when it's ceremony Working proficiency in React and TypeScript — you can pick up frontend tasks, build components, and integrate with backend APIs independently Proven experience integrating AI coding tools (Claude Code, Cursor, or equivalent) into daily development workflow — including prompt design for code generation, output validation, and actively preventing AI-generated technical debt. You can describe concrete examples of where AI accelerated your delivery and where you chose to override it Testing as a professional discipline, not a checkbox — you write unit, integration, and API tests as part of delivery, own the test pyramid decisions, and treat untested code as unfinished code PostgreSQL — schema design, query optimization, migrations in a production context AWS experience — you've deployed and operated production workloads on AWS (ECS/EKS, RDS, Lambda, S3) and can make informed infrastructure decisions Comfort working in ambiguous, greenfield settings — you define scope with stakeholders rather than waiting for pre-scoped tickets Responsibilities: Own features end-to-end: design, implement, test, deploy, and maintain across the full stack. Work split ~80% backend, 20% frontend. Make foundational architectural decisions on a greenfield codebase — data models, API contracts, service boundaries, test strategy Build and maintain the Java/Spring Boot backend that powers the product's core logic Contribute to the React/TypeScript frontend when needed — you're backend-primary, but you ship UI when the team needs it Integrate AI coding tools into your daily workflow to accelerate delivery while maintaining code quality — and help the team adopt these practices Collaborate directly with product stakeholders to refine requirements in a fast-moving, low-ceremony environment
