• We are looking for a Software Engineer to lead security across our engineering teams. This is not a client-facing or product role
• You will work across all of engineering, closely with our CISO, our CTO and our engineering leaders, bringing engineering skills to our security function and raising the bar on how we build securely. You will have the backing of the CTO and CISO, and real freedom to make change
• We want an engineer who is drawn to security, rather than a security specialist or penetration tester who has picked up some engineering. You will start by building strong foundations, then move on to the most exciting part of the role: using AI agents to test our applications continuously
• Build a clear picture of where our engineering security stands today, and agree a plan to improve it with the CTO and CISO
• Bring consistent security tooling into every pipeline, including credential scanning, software composition analysis (SCA), static application security testing (SAST) and dynamic application security testing (DAST)
• Configure that tooling to our standards so it helps engineers rather than creating noise they learn to ignore
• Review system designs and architecture with engineering teams, applying security thinking early
• Build agentic security testing: AI agents that continuously test our applications and alert engineers to issues
• Work closely with our CISO and security team, turning security goals into working systems
• Help engineers across the business build securely, through tooling, guidance and example
• After three months: you understand our systems and how we build them, and you have agreed a clear security plan with the CTO and CISO. You have an initial view of our current engineering security posture
• After six months: security scanning runs in every pipeline, tuned so that engineers trust it and act on it
• After twelve months: agentic security testing is continuously testing our applications, and security is part of how every team designs and builds
