We seek a Senior Full-Stack Engineer with 4+ years building production web apps using Next.js, TypeScript, and modern React. You’ll architect and ship features across frontend (App Router, Server Components, SWR), backend (API Routes, server actions, edge functions), and infrastructure (Vercel deployments, ISR, caching, GitHub Actions CI/CD). Must deeply debug performance bottlenecks, optimize LCP/CLS, secure API endpoints, and collaborate with product/design via Figma and Jira. Experience with PostgreSQL, Redis, and Stripe is a strong plus. You write clean, tested code (Jest, Cypress), document decisions, mentor juniors, and excel in async, remote-first teams. This is not a junior or tutorial-based role: expect autonomous module ownership, observability setup (Logtail/Sentry), and proactive architecture input. Remote (global), full-time contract. All communication and code in English. Please include GitHub/portfolio links and brief context on one complex system you shipped end-to-end.
