Senior Full Stack Javascript Engineer

5+ years of experience as a Full-Stack or Frontend Engineer building production-grade applications and/or SDKs. Strong expertise with TypeScript, React/Next.js, and Node.js. Proven experience designing, maintaining, and publishing frontend SDKs/libraries used by other developers. Hands-on experience with serverless/edge environments such as Cloudflare Workers, Vercel, or AWS Lambda. Solid understanding of API design, HTTP fundamentals, and performance optimization. Familiarity with build and packaging tools (Vite, Rollup, esbuild) and module systems (ESM/CJS). Testing experience with Jest/Vitest, Playwright, or Cypress. Excellent written and verbal communication. Comfortable working in a remote, autonomous, and async-first team.

Extend and optimize Cloudflare Worker–based APIs, as well as other serverless endpoints powering our products. Translate Figma designs into accessible, performant, and reusable React/Next.js components. Ensure reliability and quality through type-safe code, automated testing (unit/e2e), and CI/CD pipelines. Monitor, debug, and optimize production systems using Grafana, Sentry, and related tools. Drive performance optimizations — tree-shaking, code-splitting, bundle-size reduction, and build-time improvements. Collaborate cross-functionally, writing technical design docs and reviewing peers’ work to maintain high engineering standards.
