About the role

We’re looking for a seasoned full-stack engineer to lead feature development across our Nodejs, React, and PostgreSQL stack. You'll own projects end-to-end from schema design to backend APIs ensuring our platform remains fast, scalable, and reliable.

What You’ll Do

Ship high-quality code across Node.js/Express backends and React frontends.
Architect and optimize PostgreSQL databases: schema design, complex SQL, and performance tuning.
Build dynamic, high-performance React components using hooks and modern tooling.
Design and implement robust REST and real-time APIs (WebSockets).
Incorporate Redis for caching, queues, and high-throughput workflows.
Translate product ideas and customer feedback into scalable features.
Improve system observability: logs, metrics, and alerts.
Contribute to sprint planning and raise the bar on team velocity and code quality.

What We’re Looking For

4+ years of experience building and deploying full-stack applications in production.
Expertise in PostgreSQL: schema design, window functions, complex joins, query tuning.
Solid experience with Redis for caching or pub/sub use cases.
Strong system design skills; experience architecting systems independently.
Clear, concise communication and a bias for shipping.

Nice to Have

Experience with Next.js, TypeScript, GraphQL.
Familiarity with Docker, Kubernetes, and CI/CD pipelines.
Background in real-time messaging or event-driven systems.
Startup experience, especially in high-growth environments.
