About the Role
We're looking for a Senior Backend Developer to build and scale the backend behind our real-time audio/video products. You'll work primarily in Node.js, owning WebRTC-based communication features, APIs, and data layers, and you'll take responsibility for how your services behave in production.

- Design and integrate RESTful APIs, authentication, and third-party services.
- Design and optimize database schemas, queries, and indexing in MySQL/PostgreSQL, and use Redis for caching and real-time state.
- Own release readiness for your services: deploy to production, monitor behavior after release, and execute rollbacks when needed.
- Work with the DevOps team, who manage AWS infrastructure and CI/CD pipelines, to keep deployments reliable.
- Review code, mentor junior developers, and contribute to architecture decisions.
Required Skills
- 6+ years of backend development experience, with strong Node.js expertise
- Hands-on WebRTC experience, plus experience with at least one SFU (mediasoup, Janus, LiveKit, Jitsi, or similar)
- Solid experience with WebSockets/Socket.IO in production

- Experience scaling real-time systems to large concurrent user loads
- Familiarity with Docker and CI/CD tooling
