Technical Support Engineer

Braintrust is building the modern platform for evaluating and deploying AI systems. Our mission is to help enterprises build trust in their AI by making it easy to test, monitor, and improve models using real-world evaluation frameworks. We work with cutting-edge customers in finance, healthcare, and tech who are building production-grade AI systems.

At Braintrust, we believe world-class customer support is not just a function — it’s a strategic advantage. Our customers are developers building LLM-powered applications, and they move fast. We win by helping them move faster.

We're looking for a Technical Support Engineer who’s obsessed with making customers successful. Someone who will dig in, debug, escalate, build a workaround, and write a doc — all in the name of helping a customer ship. You’ll be the first line of support for developers using Braintrust, and a crucial feedback loop between our users and the rest of the company.

This role blends technical problem solving, async communication, and tight collaboration with Engineering, Solutions, and Product. If you love making tools work, explaining complex things clearly, and running through walls to unblock users — we want to talk to you.

• Own and respond to technical support issues from developers using Braintrust — primarily via Slack and email

• Debug API and SDK issues across Python and TypeScript codebases

• Reproduce bugs and work closely with Engineering to prioritize and resolve them

• Write clear, friendly explanations and surface improvements to docs, guides, and error messages

• Help users design successful evaluation workflows, even when they’re unsure what’s going wrong

• Occasionally jump in to write a script, fix a bug, or contribute to internal tools when needed

• Capture and relay customer feedback to Product and Engineering to shape roadmap and priorities

• You’ve supported technical users before (ideally developers) and know what good async support looks like

• You can write, debug, and reason through Python (bonus: TypeScript too)

• You’re comfortable learning and reasoning about APIs, SDKs, and tools quickly

• You take ownership of problems — even when they cross team lines — and follow through until users are unblocked

• You write clearly, kindly, and effectively — especially when things are confusing

• You’re curious about LLMs and excited to support tools that make AI more measurable, reliable, and trustworthy

• Experience supporting developer tools, ML infrastructure, or observability products

• Familiarity with OpenAI, Anthropic, or similar LLM APIs

• Comfort working with datasets, evaluation metrics, or prompt engineering

• Contributions to support tooling, docs, or product-led growth initiatives

• Medical, dental, and vision insurance

• 401k plan

• Daily lunch, snacks, and beverages

• Flexible time off

• Competitive salary and equity

• AI Stipend
