[Hiring] Software Engineer, AI/Agents @Seso Inc.,

Role Description

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

Qualifications

• 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

Requirements

• Experience with LangGraph/LangChain or similar agent frameworks (Nice-to-have)
• Node.js/React stack experience (Nice-to-have)
• Forward-deployed engineering (FDE) experience and comfort being customer-facing - translating real-world problems into shipped solutions (Nice-to-have)
• 3–5+ years of professional development experience (Nice-to-have)
• Based in San Francisco (preferred)

Benefits

• Comp range: $160,000 - $220,000 annually
• We carefully consider a wide range of compensation factors to determine your personal top of market.
• We rely on market indicators to determine compensation and consider your specific job related skills and experience for accuracy.
• Diversity is more than a commitment at Seso, it is the foundation of what we do.
• We pride ourselves on building the premier platform that serves agribusiness and improves the lives of agricultural workers.
• We believe in diversity of race, gender, sexual orientation, age, religion, ethnicity, national origin and all the other fascinating characteristics that make us all feel welcome.
