Profile match
We partner with VC-backed startups in EU & US to build exceptional teams — from founding engineers to C-suite leaders.

Role

We are looking for a senior software engineer to own the creation, design, and maintenance of web applications at our company. The current applications are written in Typescript using React as a framework, served through Next.js, and using React Query. You will work in an environment that is fast paced, has little technical debt, and utilizes the latest technologies.

Responsibilities

  • Own the technical vision and architecture for our web applications.

  • Lead end-to-end development of new user-facing features.

  • Break fuzzy ideas into clear specs, edge cases, phased plans.

  • Build intuitive and responsive UIs from Figma mocks.

  • Optimize application performance, focusing on Core Web Vitals.

  • Evolve React/Next.js structure: routing, state, and code‑split rules

  • Define React Query caching, retries, and optimistic updates.

  • Build a cross‑platform component library with Storybook.

  • Iteratively work with design and product leadership to create a delightful experience.

  • Represent engineering in roadmap; balance value, effort, and risk.

  • Rapid‑prototype UI/UX to de‑risk big bets with design.

Qualifications

  • 5+ years of experience as a software engineer

  • 3+ years of experience building and shipping web applications with React and Next.js.

  • Strong knowledge of TypeScript, React, and React Native.

  • Experience creating websites from Figma mocks.

  • Solid understanding of UI/UX design principles.

  • A keen eye for detail, particularly in ensuring UI elements' visual quality and interactivity.

  • Experience with ‘polishing’ UI in collaboration with a designer.

  • Experience with testing frameworks (Jest, Detox, etc.).
