Rust Engineers (Backend, Infrastructure, Security)

We build Percy, an agent that runs financial-crimes investigations for banks and fintechs. It clears false positives, escalates real risk, and writes the case narrative and audit record a regulator will read. Under it sits four years of identity infrastructure: verification, an AWS Nitro Enclave-backed vault for PII, and the APIs our customers call directly. The backend is Rust. We're hiring three Members of Technical Staff:

• Backend: the Rust APIs and services behind verification, vaulting, and the checks Percy runs. Production Rust is ideal; deep systems experience plus a real wish to learn it also works. Crypto or systems-security background counts for a lot.
• Infrastructure: own agent compute, isolation, deploys and observability across Rust services and long-running agents. Rust, Postgres/Aurora, AWS (ECS/Fargate), Pulumi/Terraform, Datadog, OpenTelemetry.
• Security: protect identity data we vault on behalf of regulated banks and fintechs, and prove to auditors every step was done right.

Small, senior team. Backed by QED, Index and BoxGroup. Customers include FDIC- and OCC-regulated banks plus Bilt, Nuvei and MoonPay. Apply: https://jobs.ashbyhq.com/footprint. I'm the recruiter and will answer questions in this thread.
