Senior Software Security Engineer — Cloud & SDLC Leader

Nothing is seeking an experienced security engineer in London to own security across backend services and cloud platforms. You will define secure development standards, integrate SAST/DAST/SBOM into pipelines, and drive vulnerability management with engineering teams.

You’ll design security testing, collaborate with privacy and legal, and lead threat modelling using AI to simulate attacks and build defences. This is a full-time London-based role with office presence.
