AI agents you can rely on. Backed by Y Combinator and Felicis.
About the role
As an Applied AI Engineer, you’ll be responsible for building, refining, and scaling the agent systems inside Sauna, from architecture to evals to deployment. We care about what works in production: fast response times, predictable behavior, traceability, and uptime.
What they're looking for
- You write production-grade code and can work across systems without needing a spec
- You'd rather ship than polish forever
- Shipped agents that live in the wild, used by customers, not just internal demos
- Familiarity with LLM ops, tracing, observability, and failure handling
- You've been a founder or early engineer, and it shows in the bar you hold your own work to
More about this role
This is a full-time, in-person role based in San Francisco (Presidio) - we work from the office 5 days a week .
You must be based in the Bay Area or willing to relocate before starting .
We require US work authorisation , but are open to O-1 or J-1 visa sponsorship for exceptional candidates.
Every tool you use was built as an island, so you became the glue between them: a name from Gmail into the CRM, a time from the CRM into Calendly, a note from Calendly into a doc. AI showed up and mostly became an eleventh window to paste into.
Sauna is a hybrid of AI and software standing on one shared brain. It holds your context and hands you real software built on top of it, so an ordinary Calendly becomes one that writes the invite itself and knows which of your busy hours bend, and for whom. Software for the path you repeat, AI for the edge that never repeats.
Wordware is the team behind it, 15 people backed by Spark Capital, Felicis, and Y Combinator with a $30M seed, the largest in YC's history. We build from an office in the Presidio, fifty metres from Crissy Field beach, and we work absurdly hard because we can see and feel the outcome every day.
