[Hiring] Senior Software Engineer - LLM Observability @Honeycomb.io

Role Description

Honeycomb is a service for the near and present future, defining observability and raising expectations of what developer tools can do! We’re working with well-known companies like HelloFresh, Slack, LaunchDarkly, and Vanguard across a range of industries. This is an exciting time in our trajectory, we’ve closed Series D funding, scaled past the 200-person mark, and were named to Forbes’ America’s Best Startups of 2022 and 2023!

The LLM Observability (LLM O11y) team builds the foundational layer that makes AI workloads observable in Honeycomb. We define how AI systems are represented in telemetry (spans, traces, token usage, cost, eval signals, etc.), and ensure that data from diverse ecosystems (e.g., LangChain, OpenLLMetry, Braintrust) is normalized into a consistent OpenTelemetry-based model.

This team owns the infrastructure and data model that all downstream AI observability experiences rely on. Our work powers everything from cost analysis to anomaly detection. If you’re excited about defining and building the “source of truth” for how AI systems behave in production, this is the team for you.

What you’ll do in the role:

• Design, build, and deliver backend systems and APIs.
• Build and maintain full-stack product features.
• Provide technical leadership.
• Collaborate across disciplines.
• Support and own your software in production.
• Communicate clearly and multiply your impact.

Qualifications

• Deep experience designing, building, and maintaining backend systems.
• Frontend proficiency with React and TypeScript.
• Experience leading complex technical projects.
• Ownership and autonomy.
• A track record of making others better.
• A collaborative and flexible mindset.
• Clear, open communication.
• An interest in observability and production culture.
• Nice to have: experience with AI-assisted development.

Requirements

• Substantial expertise building APIs and backend services in Go (or similar languages).
• Professional experience delivering frontend features and contributing to full-stack software.
• Experience navigating external dependencies and uncertainty in projects.
• Proactive identification of problems and ownership of projects end-to-end.
• Mentoring engineers and leading technical design reviews.
• Comfortable working cross-functionally and pivoting priorities.
• Experience supporting software in production.

Benefits

• A stake in our success - generous equity with employee-friendly stock program.
• Transparent pay based on experience.
• Unlimited PTO.
• Home office, co-working, and internet stipend.
• Full benefits coverage for employees, with additional coverage available for dependents.
