A business banking and treasury platform securing the flow of capital for modern companies.
Software Engineer, Security
We're building the financial infrastructure layer where business payments, cards, and treasury operations converge—and we're doing it from a security-first posture that most banks only retrofit. This team treats the kernel, the network, and the supply chain as one continuous attack surface, hardening our platform from firmware to frontend. You'll ship code in Rust and Go that locks down inter-service communication, hardens Kubernetes workloads, and reduces the blast radius of every new feature. If you believe security is an engineering discipline, not a compliance checkbox, you'll find the mandate and the budget to prove it here.
What they're looking for
- 2–5 years writing production software, with deep fluency in at least two of: TypeScript, Go, Rust, or C/C++
- Hands-on experience securing containerized workloads on Kubernetes in AWS, including IAM, network policies, and runtime hardening
- Comfort operating Kafka, Terraform, and Cloudflare tooling as part of a defense-in-depth strategy
- Track record of shipping cryptographic or authentication primitives, not just integrating third-party auth providers
- Innate bias toward simplicity and elimination—you remove unused code paths and reduce privileges as a first instinct
