Role Description We're hiring a frontend engineer who actually cares about how things feel. This isn't a "hook up some components" role. You'll be taking rough ideas and Figma files and turning them into fast, sharp, well-crafted product experiences. We use React + TypeScript. We're still early—the frontend isn't "set" yet, so you'll help define it. What You'll Do - Turn Figma into real product quickly (and not lose the details) - Build interfaces that feel fast, clean, and intuitive - Sweat the small stuff—spacing, states, interactions, edge cases - Work closely with design (and push back when something feels off) - Help build a frontend codebase that stays clean as we grow Qualifications - Are very strong with React + TypeScript - Have a sharp eye for UI/UX (you notice things other people miss) - Can go from design → production code fast - Care a lot about code quality, but don't over-engineer - Have opinions on how frontend code should be structured - Have experience working in a startup environment (or something similarly fast-paced) - Communicate clearly in English Requirements - Bonus (Not Required) - You've helped shape a design system or component library - You've cleaned up or rebuilt a messy frontend before - You've worked at a US startup Benefits - Work closely with design in a product-first environment - High ownership—you'll help define how the frontend is built - Fast-moving team with minimal bureaucracy Why This Role If you're someone who wants ownership, cares about craft, and likes building things the right way from the start, this will be a good fit. You'll have real say in how the frontend is structured and scaled.
