Key Responsibilities

1. You will design and develop high quality backend services and APIs using NestJS (TypeScript/Node.js) as part of a fast paced, high performing engineering team.
2. Build scalable and maintainable service layers leveraging NestJS’ modular architecture (modules, controllers, providers) and dependency injection best practices.
3. Apply architectural best practices including Clean Architecture, layered design, and clear separation of concerns to create maintainable and testable codebases.
4. Work closely with Product Owners, architects, and cross functional teams to translate business requirements into robust technical solutions and well-defined API contracts.
5. Take ownership of performance optimization, ensuring services are efficient, scalable, and responsive under real production loads (latency/throughput/concurrency).
6. Perform service profiling and diagnostics (CPU, memory, event-loop latency, DB query performance) to identify and resolve bottlenecks and stability issues.
7. Implement strong security practices (authentication/authorization, input validation, rate limiting, secure configuration) aligned with backend engineering standards.
8. Actively participate in the full development lifecycle including design, implementation, testing, deployment readiness, and continuous improvement of services and APIs.
9. Build and maintain strong automated tests (unit/integration) and ensure quality gates (coverage, regression, CI checks) are met consistently
10. Conduct code reviews, share best practices, and mentor junior developers to elevate team capabilities and strengthen backend craftsmanship.
11. Focus on delivering clean, high quality code aligned with strong engineering standards, reliability, and operational excellence (logging, error handling, observability
12. Collaborate in a dynamic, agile environment that values innovation, continuous learning, and engineering excellence across backend and platform services.
