Software Engineer, AI/Agents

Seso is modernizing the back-office for American farms through a workforce, HR, payroll, and agricultural labor platform. The Software Engineer, AI/Agents will design and ship production AI agents, build end-to-end product features across the TypeScript, Node.js, and React stack, and apply ML/AI judgment to make agent-based systems reliable in production.

Responsibilities:

• Design and ship production AI agents that are core to the product experience (not prototypes, not demos)
• Work across our stack (TypeScript, Node.js/React) to build features end-to-end
• Bring ML/AI judgment to product decisions as in, where agents make sense, where they don't, and how to make them reliable in production
• Move fast in a startup environment where you'll own real ambiguity and be empowered to push the boundaries

Requirements:

• Hands-on ML background and/or real experience building and shipping production AI agents (not just API calls to a model: non-trivial agent design, evals, and reliability work at scale)
• Strong TypeScript experience
• 2+ years of professional software development experience
• Experience with LangGraph/LangChain or similar agent frameworks
• Node.js/React stack experience
• Forward-deployed engineering (FDE) experience and comfort being customer-facing -  translating real-world problems into shipped solutions
• 3–5+ years of professional development experience
• Based in San Francisco (preferred)
