Artificial Intelligence Engineer

• 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
• 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

Benefits

• Remote-first work environment. The Baseten team is welcome to work from wherever they want; fully remote, in our San Francisco office, or a mix of both. Today, our team (including our founding team) is spread across the United States, Canada, and Armenia. We provide a $1,000 stipend for you to make your home-office comfortable and productive
• Regular in-person team summits. We get together as a team three times a year to plan, workshop, and most importantly, get to know each other better

• Paid parental leave. 16-weeks fully paid parental leave (adoptive and non-birth parents included) and flexibility with schedules while returning to work
• Company-sponsored 401(k) for you to contribute to
• Learning and development budget. We encourage you to take classes, attend conferences, and invest in your craft and we’ll cover expenses to make it happen- Ability to move between customer-facing product work and internal tooling and automation
• 5+ years of experience building and shipping software applications
• Ability to build accurate mental models of how systems work under the hood, including the models and harnesses you’re building on
• Comfort working autonomously in a fast-moving environment with limited structure
• Proficiency in Python, with fluency in at least one other language
• Strong software engineering fundamentals and the ability to clear a real technical bar, not just prompt well
• Strong communication skills, with the ability to bridge technical depth and business needs
• Demonstrated experience building AI or LLM-powered products, agents, or agentic workflows that real users depend on
• Experience as a founding engineer or early employee at a startup
• Experience building evals, agent observability, or tooling for non-deterministic systems
• Familiarity with agent frameworks and harnesses (LangChain, Claude Code, Codex, OpenCode, MCP)
• Experience with model development methods like supervised fine-tuning, reinforcement learning, synthetic data generation, LoRA, and full fine-tunes
• Frontend fluency
