Full‑Stack Engineer (All Levels: Junior → Mid → Senior/Team Lead)

Purpose of the Role

Build and evolve modern products across web (React/TypeScript), mobile (React Native), and backend (NestJS/Node.js) with supporting Python automation/data tasks. Depending on level, responsibilities range from shipping features and fixing bugs to owning architecture, code quality, and team leadership.

What You’ll Do (Core Responsibilities — all levels)

• Frontend (Web/Mobile): Build React/TypeScript components, screens in React Native, responsive layouts, and robust state management (React Query/Redux/Zustand).
• Backend & Data: Implement REST/GraphQL endpoints in NestJS; write efficient queries and migrations (PostgreSQL/MongoDB); integrate queues and background jobs as needed.
• Integration & Quality: Wire up frontend ↔ API ↔ database flows, add unit/integration tests (Jest/RTL/Playwright), and document decisions/PRs.
• Performance & Security: Improve Core Web Vitals, API p95 latency, and follow secure coding/auth patterns (JWT/OAuth).
• DevOps & Release: Contribute to CI/CD (GitHub Actions), containerization (Docker), and cloud deployment (AWS/Azure awareness).
• Collaboration: Work in Agile sprints, participate in code reviews, and communicate clearly across time zones.

Level‑Specific Expectations

Junior (1–2 years)

• Ship well‑scoped features and fixes in React/TS or React Native with guidance.
• Build simple NestJS endpoints; write basic SQL; create component/unit tests.
• Use AI‑assisted tools responsibly to learn faster and improve quality.

Mid‑Level (3–5 years)

• Deliver end‑to‑end slices (web/mobile ↔ API ↔ DB) with clean error/loading states.
• Define API contracts, handle pagination/caching, and add meaningful test coverage.
• Improve performance and accessibility; contribute to CI/CD and release checklists.

Senior (5–7+ years)

• Lead design for complex features; break down work; mentor juniors.
• Enforce code standards via reviews; drive reliability (observability, SLOs).
• Optimize schemas/queries; introduce queues/caching; guide cloud cost/perf trade‑offs.

Team Lead (6–10+ years, people leadership)

• Own delivery for the PH pod: run standups, capacity planning, and escalations.
• PR gatekeeper & architecture reviewer across frontend, backend, and mobile.
• Set coding/testing conventions; manage technical debt backlog and roadmaps.
• Coordinate daily with India/US; conduct 1:1s, performance reviews, and growth plans.

Tech Stack

Frontend: React 18+, TypeScript 5+, Next.js, Tailwind CSS, React Native (iOS/Android, Expo)
Backend: NestJS, Node.js, REST, GraphQL, Python (FastAPI/Flask for scripts/ETL)
Data/Infra: PostgreSQL, MongoDB, Redis, DynamoDB; S3, CloudFront, Lambda, EC2/ECS/EKS, SQS/SNS
Testing: Jest, React Testing Library, Playwright/Cypress, Detox (awareness for mobile)
DevOps/Tooling: GitHub Actions, Docker, Terraform (awareness), ADO/Jira, Datadog, Sentry
AI (nice‑to‑have): RAG patterns, embeddings, vector DBs (Pinecone/Qdrant), LLM API integration

Qualifications

Must‑Have (baseline for all levels)

• Proficiency in TypeScript, React (or React Native), and Node.js/NestJS
• Solid understanding of REST, auth, and basic database querying (PostgreSQL or MongoDB)
• Git, code reviews, and Agile experience; clear English communication

Senior / Lead Must‑Haves (in addition)

• Designing and shipping complex features end‑to‑end at scale
• Performance tuning (frontend & backend) and secure coding practices
• CI/CD ownership, observability (logs/metrics/traces), and architectural decision‑making
• (Lead) 2+ years managing 5–10 engineers: standups, reviews, coaching, capacity, handoffs

Nice to Have

• React Native in production; GraphQL; queues (Bull/SQS); caching (Redis)
• AWS or Azure hands‑on; Terraform; feature flags/canary releases
• Python data pipelines/ETL; AI integration (RAG, vector search)
• Open‑source contributions or published technical articles
