AI Agent Engineer Jobs at Startups

AI agent engineers build systems where models act, not just answer: tool calling, planning, memory, and orchestrating several agents to finish a task end to end.

These roles are at early-stage startups, from seed to Series B. Teams are small, so engineers own more of the product, ship faster and often get meaningful equity, in return for less structure and more risk than at a large company.

Sierra, Moveworks and Parloa have the most open roles here right now. Of these, 13% can be done remotely and 4 say the company sponsors visas. The skills these postings ask for most are AI Agents, Python, TypeScript and LLM.
