Senior Software Engineer II - LLM Observability

Honeycomb is a fully distributed observability platform for developers. The team builds observability for AI, helping customers see what their agents are doing, what those agents cost, and where errors happen. You'll work in a small, cross-functional group of engineers with a dedicated product manager and designer, shipping features customers use in production.

• Own end-to-end development of AI observability capabilities, from ingestion to in-product visualizations.
• Architect and evolve the data model and infrastructure that let us observe agents and their ecosystems across the Honeycomb product.
• Build systems that analyze and surface AI-specific signals, such as cost, token usage, errors, and anomalies.
• Collaborate with product and design partners to ensure what we build is usable, intuitive, and unlocks meaningful user workflows.
• Teach best practices for exploring and understanding AI system behavior across conversations and workloads.
• Iterate through fast feedback loops and experimentation, and share both wins and failures.

• Significant software engineering experience, with a record of shipping and owning features end to end.
• Experience shipping customer-facing features at a SaaS company, beyond internal tooling.
• Full-stack range, with proficiency in backend development (Go and/or Python) and frontend development (TypeScript and React).
• A track record of working closely with product managers and designers.
• Regular, hands-on use of AI tools in your day-to-day engineering work.
• Experience being on call; you'd join the rotation after about 90 days.
• A track record of navigating ambiguity in a fast-moving field where requirements shift and experimentation is a core part of the job.
• Bonus: Experience building LLM or agent-powered features in production.
• Bonus: Hands-on experience with observability tooling, such as OpenTelemetry.

Base Salary: $183,340—$206,000 USD. Benefits include generous equity, unlimited PTO, home office/co-working/internet stipend, full benefits coverage for employees, up to 16 weeks of paid parental leave, and an annual development allowance.
