Staff Security Engineer

You will set the technical direction for security across DigitalZone's platform, from application and cloud security to the payment and identity flows at the core of the business. This is the most senior individual-contributor security role: you own the hardest problems, do the hands-on work, and raise the bar for the whole engineering org. You can read the code, build the tooling, and fix the issue, not just file it. What you'll do: Design and mature the secure SDLC, to support engineers in prioritising and remediating findings: Application Security: Leverage deterministic and LLM assisted automation to identify and remediate vulnerabilities across code developed within DigitalZone. Supply Chain Security: Design and implement solutions to mitigate the risks of vulnerable and compromised 3rd party dependencies. Including, the verification of feature and release integrity. Infrastructure & Cloud Security: Integrate scalable solutions to identify and patch vulnerabilities across the container and cloud infrastructure delivery process, including scanning, signing, admission control and runtime security. Run vulnerability management and coordinate penetration tests, and defining and tracking key vulnerability metrics. Define secure-by-design patterns and success criteria for authentication and authorization, cloud networking, secrets management, and IAM. Act as the primary liaison between customers and security vendors, driving alignment on security findings, remediation priorities, risk acceptance decisions, and strategic security outcomes. What you'll bring 8+ years in software or security engineering with deep hands-on depth across application security, cloud/infra security, and detection and response. Strong track record threat modeling and securing systems that handle payments or sensitive financial and PII data. Strong engineering fundamentals: fluency in AWS security, modern authentication and authorisation patterns, and at least one of our core languages.
