Sr Backend Engineer - AI

Responsibilities

• You will be working with the high-caliber team in some of the below areas.
• Noz, AI teammate: agent orchestration, tool execution, and the APIs that stream results back into the product
• SigNoz MCP server that exposes observability data to LLM agents, so any agent can query a user's logs, metrics, and traces
• The hard parts of agent backends: long-running execution, security, streaming over SSE, tool calling, and session state across DBs
• LLM/GenAI observability, so teams (including us) can monitor their own AI apps with OpenTelemetry
• What will make you successful
• 5-8 years building backend systems in production. You'll work across both Go and Python.
• Strong with Go (concurrency, channels, performance) and with async Python (FastAPI, Pydantic, asyncio), and comfortable designing APIs and data models.
• You have built and shipped LLM features in production: agents, tool or function calling, evals, MCP, context and prompt engineering. You know how to make a non-deterministic system behave like a dependable one.
• Experience building distributed systems while writing clean and scalable code
• Ability to drive initiatives end-to-end: from problem discovery → design → implementation → rollout
• Comfortable working in a high-ownership, fast-moving, remote-first environment
• Strong communication skills, can write clear tech docs and explain trade-offs

Requirements

• Past experience in AI or platform teams of series B+ startups
• Experience in observability (monitoring / logging / tracing)
• Familiarity with OpenTelemetry and/or ClickHouse, Kafka, Kubernetes, etc.
• Loves open source, ideally with prior contributions to OSS projects (any size)
• Why you'll love working at SigNoz
• You'll help define agent-native observability, a new category, not maintain a mature dashboard product.
• Work on a globally used open-source project that engineers actually love
• Collaborate with high-caliber team who just can't stop shipping
• Remote-first, async-friendly culture
• Opportunity to help define the future of open-source observability
