Responsibilities:

- Backend ownership: Design and maintain Node.js/NestJS services for message storage, retrieval, and state sync
- API design: Build well-typed REST contracts for Threads and Composer operations
- Data layer work: Model and optimize MongoDB/Firestore schemas for high read/write volumes and atomic updates
- Scalability & resilience: Implement queues, caching, and rate limiting to handle burst traffic gracefully
- Frontend integration: Ship modular Vue 3 UIs that consume your APIs efficiently and handle realtime state updates
- Observability: Instrument logs, metrics, and traces to monitor latency, error rates, and throughput
- Testing discipline: Maintain high coverage across unit, integration, and contract tests
- Production ownership: Participate in on-call, debug incidents, and drive post-mortem action items to closure
- Collaboration & mentorship: Work closely with Product and Frontend leads while reviewing code and supporting junior engineers

Requirements:

- 4+ years of professional engineering experience, preferably backend-heavy full-stack work
- Expert in Node.js and TypeScript; comfortable with NestJS or Express microservices
- Proficient in Vue 3 or similar modern frontend frameworks
- Strong understanding of API design, data modeling, and distributed system patterns
- Experience with GCP (or AWS), containerization, and CI/CD automation
- Hands-on with observability and production monitoring
- Bonus: Pub/Sub or message queue experience; event-driven or domain-driven design background

Technical Environment:

- Backend: Node.js, TypeScript, NestJS / Express, REST APIs
- Frontend: Vue 3, TypeScript, Pinia, Vite / Webpack, Tailwind
