The position

⚠️ Please read first

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 authorization , but are open to O-1 visa sponsorship for truly exceptional candidates.

Roles & Responsibilities

As an Applied AI Engineer , you'll be responsible for building, refining, and scaling the agent systems inside the company — from architecture to evals to deployment.

This isn't a research role. We care about what works in production : fast response times, predictable behavior, traceability, and uptime.

You'll work across the stack — with infra, frontend, and product — to make sure the agents users build inside the company are robust, useful, and usable.

A few examples of what you might work on :

Implement multi-step, tool-using agents that hit real APIs and handle retries, auth, timeouts, and edge cases.

Build RAG pipelines that support grounded answers from structured and unstructured sources.

Design agent memory systems that persist relevant state across runs — e.g., scratchpads, summary buffers, embedding stores.

Add determinism + replay to agents so users can trace and debug behaviors step by step.

Own and evolve our eval framework — both automated checks and human-in-the-loop scoring.
