Senior Full Stack Engineer:

• 6–9 years of professional software engineering experience, including 6+ years building/operating backend systems in Python at scale.

ROLE SUMMARY:

As a Senior Full Stack Engineer you will own features and services end to end — from frontend architecture to scalable backend services and their production operation. You will design systems at the module and service level, make performance, scalability and security decisions, carry on-call and production ownership, mentor engineers, and help shape technical direction within your team.

WHAT YOU’LL DO:

• Own features and services end to end, from design through production operation
• Design systems at the module and service level: frontend feature modules, routing and reusable component library/design system; backend multi-service workflows, tool layer and retrieval
• Lead the team’s testing strategy: strong component tests + Playwright E2E in CI, reducing flakiness
• Make performance decisions: code-splitting, rendering optimization, bundle analysis, Core Web Vitals; backend concurrency limits, queueing/backpressure and benchmarking
• Make scalability decisions for workflow reliability: idempotency, compensation, isolation, multi-tenant readiness, cost/latency controls
• Make security decisions: AuthN/AuthZ (JWT/OAuth/service-to-service), secrets, auditing and access controls
• Hold on-call and production ownership: SLOs, incident playbooks, postmortems, observability and capacity planning
• Mentor engineers and drive review discipline and accessibility standards
• Help shape technical direction within the team

MUST-HAVE:

Frontend:

• Strong production experience with React + TypeScript (hooks, routing, React architecture)
• Tailwind CSS at scale — consistent patterns and reusable UI primitives
• Testing with React Testing Library, Jest/Vitest and Playwright E2E, integrated in CI
• State and caching with React Query/SWR and Zustand/Redux Toolkit
• Accessibility standards (WCAG).
• Refactoring and frontend architecture ownership (feature modules, component library, design system)
• Testing leadership: CI integration and flaky test debugging
• Performance profiling and optimization: code splitting, bundle analysis, Core Web Vitals, Lighthouse

Backend / Platform:

• Strong Python backend ownership(FastAPI preferred) and production API design: versioning, pagination, error contracts
• Streaming via SSE/WebSocket
• SQL/PostgreSQL: data modeling, schema design, indexing and query optimization; Redis caching
• Concurrency: asyncio, thread pools, process pools a…
