Software Engineer, AI/Agents

About the role:

Seso is building the first modern payroll and workforce platform for agriculture, an industry that's been ignored by every other HR/payroll company because it's "too hard." We're growing fast, and we're looking for an engineer who's genuinely AI-native: not someone bolting a chatbot onto a product, but someone who thinks in agents, evals, and production ML systems as a default way of building software. We’ve shipped our first agents, and need a true thought partner to help level up our game.

What you'll do

• 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

Must-haves

• 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

Nice-to-haves

• 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)
