About this role
Your mission <ul><li>Design and build modern React / Next.js applications that stay maintainable as they grow.</li><li>Make and defend architectural decisions — and understand the performance consequences of them.</li><li>Set front-end standards, build reusable components, and create patterns the whole team builds on.</li><li>Work closely with our back-end developers to integrate APIs and business logic cleanly.</li><li>Own quality end to end, including in production: reading logs, tracing issues, and diagnosing incidents together with our DevOps and sysadmins rather than handing them off.</li><li>Improve performance, accessibility, and overall UX across projects.</li><li>Review code, raise the bar, and help good front-enders across our teams become even better — without slowing them down.</li></ul> Your profile <ul><li>5+ years in front-end development, with deep, current React and TypeScript experience.</li><li>Real production experience with Next.js — you understand rendering strategies (SSR / SSG / ISR / CSR), hydration, routing, and <em>when to use which</em>, not just how to scaffold an app.</li><li>A strong grasp of front-end architecture: component design, state management, and how structural choices affect maintainability, bundle size, and runtime performance.</li><li>The ability to measure and improve performance (Core Web Vitals, bundle analysis, profiling) — and to understand the cost of the trade-offs you make.</li><li>Solid experience integrating front-ends with APIs and back-end systems.</li><li>Comfort across the full lifecycle: version control, testing, debugging, CI/CD, deployment, and maintenance.</li><li>Excellent English and the confidence to work directly with product owners and clients.</li><li>Senior judgment: you know when to be rigorous and when to be pragmatic, you take ownership of outcomes, and you make the people around you better.</li></ul><strong>Nice to have:</strong> Python/Django and SQL (you'll work closely with our back-end teams), real depth in accessibility, a good design sensibility, or experience setting standards within a team.
