The Role

As a Senior Security Engineer ,



you will be the cornerstone of our product and cloud security posture. You will own security across the code, the cloud, the pipelines, the corporate estate, and the response when an alert comes in. This is a hands-on role with real architectural ownership. You will design our security controls and then build them — our security team is small, and you will be one of three people, so there is nobody to hand a design to. That cuts both ways: almost nothing stands between a good idea and it being live, and there is nowhere to hide if it doesn't get delivered. If your recent work has been mostly programme management, vendor oversight or reviewing other people's designs, this won't be the right fit.
Much of the work will also happen through other people. Security can't do everything alone, so you will spend real time with developers and architects — reviewing designs, threat modelling, coaching on secure practices — and you
