Security Engineer

Augustus is building a modern correspondent bank from scratch, combining a real national bank charter with Marble, a proprietary core banking system built around intelligence and code. The company is backed by over $200M from leading venture firms and founders of major fintech companies, and is regulated in Europe while expanding to the US.

You will own security engineering end-to-end across application, infrastructure, and incident response, partnering with product and platform teams during design and shipping security automation in production. Your focus will be on measurable risk reduction that keeps product velocity high. You will help define security in a greenfield modern bank, moving beyond threat modeling to harden cloud and CI/CD paths, build detection and response workflows, and drive remediation to closure with clear risk tradeoffs. This role reports to the CISO and involves establishing secure development lifecycle practices, building AI-native product-security review pipelines, and expanding baseline coverage for workload identity hardening and secret management across critical services.
