Senior Security Engineer - Monitoring & Detection

Job description

We help UK public sector organisations build and run digital services that are secure, trustworthy, and resilient. As a Senior Security Assurance Engineer in our Cyber practice, you'll take end-to-end ownership of security assurance work across complex government environments - designing audit approaches, leading risk assessments, and helping clients understand and improve their security posture in ways that are proportionate, practical, and grounded in how their services actually work. This is a role with real scope. You'll operate across client engagements where the stakes are high - services that handle sensitive citizen data, systems that need to meet GovAssure and Cyber Assessment Framework requirements, and programmes navigating a demanding regulatory landscape that includes UK GDPR, the NIS Regulations, and the HMG Security Policy Framework. You won't be applying cookie-cutter frameworks; you'll be making informed judgements about what's proportionate for each context and helping clients make better decisions about risk. At Senior level, you're also expected to raise the standard of security practice around you - not just through your own work, but by mentoring colleagues, contributing to how the team operates, and helping clients build their own capability over time. We're a consultancy that believes good security outcomes come from embedding security into delivery as a continuous concern, not bolting it on at the end. You'll be central to making that real.
