We’re looking for Mid+/Senior FullStack JS developers who love technical interviews. Your primary responsibility is to pass client technical assessments (live coding, architecture/system-design conversations) across both frontend and backend (Node.js/NestJS). You’ll help us win projects by demonstrating deep technical capability and clear communication — while sharpening your own skills across many interview styles and stacks.
What you’ll do: * Join client technical screens as the hands-on engineer, solve problems live, and explain trade-offs with clarity. * Navigate a variety of interview formats: algorithmic/DSA rounds, frontend architecture/performance/testing/accessibility, backend design with Node.js/NestJS, API design, testing, networking, and security basics. * Discuss modern FE stacks (TypeScript, React or Vue, Vite/Webpack, SSR/ISR) and robust BE stacks: * Node.js with NestJS (or Express/Fastify), TypeScript first. * API patterns: REST/GraphQL, WebSockets, pagination, versioning, error models. * Data layer: PostgreSQL/MySQL, MongoDB, Redis (caching, sessions, rate limiting), ORMs (Prisma/TypeORM), migrations, indexing. * Integration: queues/streams (RabbitMQ/Kafka/SQS), file/object storage, third-party auth/payments. * Cloud & ops: Docker, basic CI/CD, env/config management, logging/metrics (e.g., ELK/EFK, OpenTelemetry), 12-factor sensibilities, some experience with Cloud (AWS/Azure/GCP).
You’re a great fit if you: * Have 5+ years of professional experience in frontend + backend engineering. * Are fluent in TypeScript; expert in React (preferred) or Vue, and confident with Node.js/NestJS (routing, modules, DI, pipes/guards/interceptors). * Can reason about rendering (CSR/SSR/SSG/ISR), state (local/global/query), performance (code-splitting, memoization, hydration), and accessibility (ARIA, WCAG). * Can design backends with solid domain boundaries, data modeling, transactionality, caching, and consistency; you understand indexes, query plans, and when to choose SQL vs NoSQL. * Are comfortable with live coding (practical FS tasks + algorithms), system design for the web (load shedding, CDNs, caching layers, queues, pub/sub, eventual consistency), and security basics (OAuth2/OIDC/JWT, CSRF/CORS, CSP, input validation, OWASP Top 10). * Write tests when it matters: Jest/Vitest, RTL, Supertest, contract tests; can discuss coverage vs. ROI. * Communicate clearly in English (B2+), keep calm under pressure, and enjoy explaining your thinking.
Apply: Send your CV/LinkedIn + GitHub/portfolio + a short note on your strongest interview topics. If you have preferred stacks, mention them. We’ll invite you to a brief intro call followed by a friendly mock round.
