London, UK (Hybrid – 3 days in office) / Office location: Central London (Victoria area)
About the Role
We are looking for a Product Engineer who is highly product-minded, fast-moving, and comfortable owning front-end development in a startup environment. This role sits at the intersection of engineering, product thinking, and execution, with a strong emphasis on Point of Sale (POS) systems.
You will work closely with founders and engineers to build, improve, and scale a POS platform used on tablet devices. While the team has strong backend coverage, the biggest need is on the front end, particularly around React, TypeScript, and React Native.
This is a hands-on role for someone who enjoys moving quickly, shipping features, and maintaining high UI and code quality while working in an AI-accelerated development environment.
Key Responsibilities
-
Own and build front-end features for a POS product used primarily on tablet devices
-
Work extensively with React, TypeScript, and React Native (some Next.js exposure)
-
Improve UI/UX quality and refactor existing codebases to maintain performance and cleanliness
-
Collaborate closely with backend engineers while focusing primarily on front-end delivery
-
Apply strong product thinking: understand the product deeply and translate requirements into high-quality implementations
-
Help guide and mentor other developers when needed
-
Move fast in a startup environment while maintaining code quality
-
Leverage AI tools in development workflows while ensuring long-term maintainability

Engineers who thrive in fast-moving environments and enjoy ownership
-
Candidates who care deeply about UI quality and performance
