Opis stanowiska
About the Role
We're seeking a Full Stack Developer to join our product team and contribute across backend architecture and customer-facing interfaces. You'll collaborate with the Team Lead, Product Manager, and Product Designer to build reliable, secure, high-quality software.
As part of the team, you'll participate in code reviews, uphold strong testing practices, and effectively use AI-assisted development tools like Cursor or Claude Code.
What You'll Do
Backend Development
• Build and evolve backend applications in .NET 10 and C# 14
• Design REST APIs that are consistent, secure, and well-documented
• Work with PostgreSQL database structures, and help optimize queries, indexes, and overall performance
Frontend Development
• Build user interfaces in Angular/React and TypeScript
• Take an active role in our frontend rewrite using Angular/React
• Ensure UI implementations are performant, maintainable, and true to the product design
Quality & Testing
• Treat unit and integration testing as a core part of development, not an afterthought
• Participate in code reviews with clear, constructive feedback
• Write clean, secure, maintainable code aligned with our standards
AI-Assisted Development
• Use AI tools (Cursor, Claude Code, or similar) to accelerate development, code analysis, and refactoring
• Critically evaluate the correctness, quality, security, and performance of AI-generated code before it ships
Delivery & Collaboration
• Work within GitHub and CI/CD to deliver features reliably and on time
• Collaborate closely with your Team Lead, Product Manager, and Product Designer, and actively participate in Agile ceremonies
• Share knowledge with the team
What We're Looking For
• Solid hands-on experience with .NET and C#
• Experience building interfaces in Angular/React and TypeScript
• Experience designing REST APIs and working with PostgreSQL
• A genuine testing habit — unit and integration tests as standard practice
• Comfort participating in code reviews and giving direct, useful feedback
• Practical experience with AI-assisted development tools, and the judgment to critically assess what they produce
• Good command of English and strong collaboration skills within a cross-functional team
Why This Role Matters
This isn't just about shipping features — it's about contributing to a team that raises its own technical bar. You'll have real input into technical decisions, architecture, and process, working alongside a Team Lead, Product Manager, Product Designer, and the wider Engineering and Platform teams.
