Job responsibilities:

• Core backend systems: Design, implement, and optimize multi-tenant NestJS/Prisma/PostgreSQL services and APIs powering spaces, assistants, knowledge access, and conversational workflows.
• AI platform capabilities: Enhance the LLM orchestration layer (streaming, tool calling, multi-model routing), integrate Python/MCP tools, and drive lower latency, higher reliability, and better cost efficiency.
• Async and real-time architecture: Build event-driven workflows with RabbitMQ for reliable background and inter-service messaging, and maintain a responsive real-time chat delivery pipeline.
• Platform ownership: Elevate observability (metrics, structured logs, dashboards, alerts), own K8s/Helm production delivery with ArgoCD GitOps, and contribute shared backend platform packages.
• Engineering culture: Ensure quality with robust unit/integration tests, lead in reviews and architecture patterns, and mentor peers to raise backend reliability and maintainability.

Job requirements:

• 5+ years of backend engineering experience with strong expertise in TypeScript, Node.js, and NestJS
• Strong system design skills: you can reason about distributed systems, define clean service boundaries, and make pragmatic technical trade-offs
• Deep database knowledge: schema design, query optimization, and migration strategies in PostgreSQL; Prisma experience is a plus
• Experience building reliable production APIs and backend services with real operational constraints
• Security awareness: comfortable with multi-tenant data isolation, authentication and authorization patterns, and auditability in enterprise software
