Senior Cyber Security Engineer | £70,000 – £90,000 DOE | Hybrid – Liverpool Street, London (2–4 days/week in office)
We are looking for a Senior Cyber Security Engineer to join a growing security function, replacing a departing team member and stepping into a role with real ownership from day one. This is a hands-on, engineering-led position for someone who has worked operationally inside a business rather than purely on the consultancy side, and who is comfortable engaging directly with customers and stakeholders with minimal onboarding. You’ll bring deep, practical experience across SASE/SSE, vulnerability management, and EDR, working independently to support and advise on a modern security stack while helping shape best practice across the team.
Why this role stands out:
- Genuine hands-on autonomy — work directly with customers rather than sitting behind layers of process
- A modern, well-invested security stack (Zscaler/Netskope, Microsoft Purview/Defender/Sentinel, Rapid7) with real scope to bring your own operational experience to bear
- Flexible hybrid working, with terms agreed upfront for the right senior candidate rather than shifting after you join
- Act as a senior technical point of contact for customers, engaging confidently and independently from day one
- Design, implement, and support SASE/SSE deployments (Zscaler and/or Netskope)
- Lead on vulnerability management and EDR operations, from configuration through to remediation guidance
- Provide input and guidance on DLP strategy and controls where relevant
- Support and advise across the Microsoft security stack (Purview, Defender, Sentinel) where applicable
- Contribute to incident response and exposure management activity, drawing on real-world operational experience (Rapid7 exposure welcomed)
- Act as a mentor and technical escalation point for more junior members of the team
- Bring a proactive, opinion-forming approach to customer conversations rather than a purely reactive one
- Essential: hands‑on experience with Zscaler and/or Netskope (SASE/SSE)
- Strong working knowledge of vulnerability management and EDR platforms
- DLP awareness or hands‑on experience is a plus
- Experience with the Microsoft security stack (Purview, Defender, Sentinel) is a strong bonus
- Experience with Rapid7 (incident response and/or exposure management) is valued
- Real-world incident response experience, not just platform familiarity
- A genuine passion for cyber security and a proactive, authentic approach to customer engagement
- Senior-level autonomy and direct customer ownership from day one
- Flexible hybrid working, agreed in writing
- Exposure to a modern, well‑resourced security toolset
- Genuine scope to shape process and mentor junior colleagues
