Full Job Description

San Francisco (FiDi), CA · On-site · Full-time
Compensation: $200,000–$350,000 + competitive equity

About the Company

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.

The Role

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)

Requirements

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

Green Flags

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.

Red Flags

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.

Why Join

Funded momentum: $30M+ raised across two rounds in five months
Build agent products 0-to-1 on a fast-scaling surface
Founding-track experience on a small, fast-moving team
Full benefits, Equinox membership, private chef
