AI Engineer

ABOUT BASETEN

Baseten powers mission-critical inference for the world's most dynamic AI companies, like Cursor, Notion, OpenEvidence, Abridge, Clay, Gamma, and Writer. By uniting applied AI research, flexible infrastructure, and seamless developer tooling, we enable companies operating at the frontier of AI to bring cutting-edge models into production. We're growing quickly and recently raised our $1.5B Series F , led by Altimeter Capital, Conviction Partners, and Spark Capital. Join us and help build the platform engineers turn to ship AI products.

THE ROLE

Are you the person on your team who builds the agent everyone else ends up using? We're looking for an AI Engineer to join our Training Product team and do that at Baseten. You'll build AI-driven product features for the customers training and post-training frontier models on our platform, and you'll raise the ceiling on how Baseten itself uses AI internally, turning manual workflows into agentic ones that make every other team faster.

You'll work directly with our research engineers to scope and build products, taking ideas from a research loop that already works internally to something customers can run themselves. This is a hands-on role with real autonomy. You'll pick the problems worth solving, build the harnesses, execution flows, and guardrails that make AI systems reliable, and own the results. If you've been shipping agents and want that to be the job, let's talk.

RESPONSIBILITIES

Build and ship agentic product experiences, including chat-style and assistant-like interfaces, from prototype to GA.

Design the harnesses, execution flows, and guardrails that make AI systems reliable in production.

Build internal automation and AI tooling that measurably increases the velocity of engineering, research, and go-to-market teams.

Partner with research engineers to scope product opportunities out of internal research workflows and turn them into customer-facing features.

Define and instrument evals so you know whether a change actually improved output quality.

Work throughout the stack (API layer, backend, agent orchestration, frontend) to implement features end to end.

Use Baseten's own training and inference products yourself to develop intuition around customer workflows.

Identify where AI can replace manual process across the company and build the thing rather than write the proposal.

Fix bugs and resolve customer issues with urgency.

REQUIREMENTS

5+ years of experience building and shipping software applications.

Demonstrated experience building AI or LLM-powered products, agents, or agentic workflows that real users depend on.
