Founding AI Engineer
$160k - $220kRiver
Job Description
About River
\nRiver builds AI voice agents that sell for B2B SaaS companies. Our agent qualifies prospects, handles hard questions, and demos the product live in a browser while it talks. We just closed our pre-seed (backed by the founders of Ramp, Kalshi, and JumpCloud) and have paying customers.
\n \nThe role
\nYou'll build River's agent: how it listens, reasons, calls tools, drives a browser, and handles a buyer who goes off script. You'll join a small founding team and work directly with the founders.
\n \nWhat we look for
\n- \n
- 3+ years shipping software, with senior or founding-level ownership of a product in production \n
- You've shipped agents real people relied on, and can walk us through what broke \n
- You've built agent capabilities beyond off-the-shelf tools: tool use, memory, planning \n
- You find the problem, propose the fix, and ship it \n
Nice to have: voice or real-time (WebRTC, streaming), browser automation, a startup of your own.
\n \nThe details
\n- \n
- In person in New York, relocation supported \n
- $160K to $220K base, around 1% equity \n
- US work authorization required; no visa sponsorship \n
To stand out: send us the agent you're proudest of and the hardest thing that broke. A link beats a cover letter.
