Job summary

Shelf is building an AI-native platform in Warsaw, offering engineers ownership across frontend, backend, and production quality. You will ship end-to-end product experiences, shape technical and UX approaches, and advance internal workflows with modern tooling.

The role emphasizes strong technical skill, clear product judgment, and rapid learning in a fast-growing environment with enterprise-grade security and reliable operations.

Qualifications

• 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 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.
• A security-conscious approach to engineering: you handle sensitive data carefully and think about security implications.
• 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.

Responsibilities

• 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
