Responsibilities

For four years, our backend systems helped answer one question: should this company onboard this user? The clear cases were automated; the ambiguous ones went to a human who worked each case by hand. That's where the fraud worth catching tends to be.
Footprint's risk agent, Percy, goes after that queue: an agent that can do more in review than a person can, and faster. The identity verification platform underneath it was built for bounded request/response work, and now agent-shaped workloads ask different questions of it. There's little precedent to copy.
You'd span both worlds: the platform financial services run on today, and the agentic products we're building on top of it.
You'll report directly to the Head of Engineering - Elliott Forde.
API and service design. The Rust APIs and services powering verification, vaulting, and the checks Percy runs to investigate users for fraud. These are the surfaces our customers' products call directly, which makes the design decisions hard to take back
Product areas, end to end. A whole area becomes yours: data model, architectural calls, deploy. You take features from ideation through production with design and frontend, and you're in the planning conversations that decide which ones happen
Systems that hold up to scrutiny. Our customers are banks and fintechs, and their auditors and security teams read what we build. Correctness, reliability, and the security posture of your services are yours to set and defend
The agent-shaped work. Percy's investigation services are the newest and least settled part of the backend. What excellence looks like here is still being decided, and you'd be one of the people deciding it

Deep experience with most of this, and the judgment to pick up the rest, is what matters.
4+ years designing, building, and operating backend systems under real load - including debugging them when they broke
You've shipped and operated an API that engineers on other teams or outside your company build against, and handled the compatibility problem when it had to change
