About the role

Under the hood, Braintrust is a real-time, high-availability data platform that operates in both SaaS and self-hosted environments.
You'll help scale our ingestion pipelines, evolve our open source libraries, and ensure everything runs reliably, observably, and fast.
If you thrive in a fast-paced environment and enjoy solving hard systems problems with a product mindset, we'd love to work with you.

As a backend engineer at Braintrust, you'll help build the core platform powering LLM-native development:
Design and ship features that give users deep insight into their LLM usage and performance.
Develop and evolve robust, efficient open source libraries for tracing and evaluating LLM calls inside customer applications. Check out our SDKs https://github.com/braintrustdata
Build highly available real-time data pipelines to ingest, store, and query large volumes of structured and semi-structured AI usage data.
Support for parsing and uploading attachments from LLM multimodal outputs into long term storage.
Strong systems thinking: you've owned or contributed to infrastructure projects and know how to design for scale, uptime, and data integrity
Comfortable with ambiguous problems and excited to partner across the company to ship impactful work
Clear communicator who documents decisions, shares context, and helps lift the team

Experience with observability tooling (e.g., Grafana, Prometheus, Datadog, or similar) and a passion for making systems operable, available and rock solid.

Braintrust is the agent observability platform.
By actively applying intelligence to agent traces and automatically surfacing the most critical patterns, Braintrust gives teams the visibility to understand how agents behave in production and the tools to improve them.
Teams at Notion, Stripe, Box, OpenAI, and Cloudflare use Braintrust to trace their agents, find the issues in their observability data, and run evals that tell them how to improve.
Integrate, proxy, cache, and collect data from OpenAI, Anthropic, Gemini, and other major model providers that our customers rely on.
