We can talk into the 100k+ range. Most security jobs want reviewers. My client wants builders. If your idea of Security Engineering is sitting in review queues, approving pull requests, or filling out spreadsheets for auditors, this isn't the role for you. They're a regulated payments fintech scaling towards banking‑licence territory and rebuilding Security Engineering around automation, platform thinking, and shared ownership.
They're looking for a Senior Security Engineer who can help them scale security through engineering, not process. You’ll work across:
- Payment Cryptography – HSM operations, key ceremonies, PCI PIN, payment key lifecycle management, DUKPT, TR‑31/34.
- Application Security at Scale – building automated AppSec capabilities, not manual review queues.
- Pipeline Security – policy‑as‑code, CI/CD controls, SAST tooling, compliance automation, and developer‑first security.
What We’re Looking For
- 5+ years in Security Engineering
- Strong production Go experience (essential)
- Experience building and running security platforms/services
- Cloud security expertise, particularly AWS
- Hands‑on payment cryptography experience
- Strong AppSec background covering SAST, DAST, SCA and threat modelling
What This Isn’t
- Red‑team only
- GRC or audit focused
- Cloud‑KMS‑only cryptography experience
Why Join?
Security here isn’t a gatekeeper function. Their job is to build the tooling, platforms and guardrails that help engineering move faster and safer. You’ll get exposure to banking‑scale security challenges, deep payment cryptography work, and the opportunity to shape a security function that’s being rebuilt from the ground up. If you’re an engineer who does security – not a security person who occasionally scripts – we should talk.
