We’re looking for a Cyber Security Engineer to help improve application security across the FT’s cloud-native technology estate. This is a hands-on role focused on making secure engineering easier for product, platform and software engineering teams. Application security experience is essential for this role. You’ll help improve developer-friendly security guardrails across GitHub-based CI/CD pipelines, application repositories and engineering workflows. This includes working with SAST, software composition analysis, secret scanning, vulnerability management and secure coding guidance so that security findings are clear, actionable and owned by the right teams.
