San Francisco (FiDi), CA · On-site · Full-time
Compensation: $200,000–$350,000 + competitive equity
An AI infrastructure company building behavior-monitoring tooling for autonomous AI agents in production — surfacing behavioral anomalies like instruction drift and context retrieval loss that traditional observability misses. Hundreds of teams building agents rely on the platform to understand how their systems behave post-deployment, cluster patterns across workflows, and pinpoint where reliability breaks down. Recently raised $30M+ across two rounds in the past five months, backed by leading venture and angel investors. ~19-person team.
Build high-taste products for self-learning agents. The role is majority agent work on a full-stack baseline. Candidates can come from a front-end/design engineering background or an AI engineering background, but both must have prior experience building and designing agents, ideally at a startup with 0-1 product ownership.
What you'll be doing
-
Build high-taste agent products that pair powerful behavior with consumer-grade UX polish
-
Design and ship agent capabilities from 0 to 1 inside a fast-scaling product surface
-
Contribute across the full stack as needed, with the majority of work on agent infrastructure and product
-
Translate customer feedback on agent behavior into concrete product iterations
-
Help raise the bar on product taste and craft as the team grows
Tech stack: TypeScript (full-stack)
-
3-7 years engineering
-
Agent or Applied AI background required
-
0-1 product ownership comfort
-
Front-end/design engineer or AI engineer
-
TypeScript fluency
-
Evals experience heavily preferred
-
Shipped agents in production at a startup. Can walk through context design, tool design, reasoning loop tradeoffs.
-
Strong product engineering range. Has shipped customer-facing product features end to end, not just backend infrastructure or research artifacts.
-
Demonstrably strong communicator. Customer calls, internal demos, technical writing, public talks, or comparable signal of comfort explaining complex AI concepts.
-
Prior evals, observability, or behavior-monitoring product experience. Direct adjacency to our space, heavily preferred.
-
Prior 0-1 product ownership at a seed or Series A startup. Built agents from a blank page.
-
High-intensity background signal: olympiad medals, debate competitions, competitive athletics, founder experience, or comparable high-output indicators.
-
No prior agent or Applied AI experience. The bar is production agent work.
-
Front-end or design engineering only without agent depth.
-
Backend or infrastructure only without product-shipping experience or customer-facing range.
-
Weak customer-facing skills. The seat is customer-facing, candidates who want heads-down only are not the fit.
-
Traditional ML or model-training background without agent system experience.
-
Cannot or will not work 5 days in person at the FiDi office.
-
Funded momentum: $30M+ raised across two rounds in five months
