Are you looking for an exciting new opportunity?

Join an independent AI and data security partner helping private equity firms and their portfolio companies uncover hidden savings, validate protection, and maximise ROI from their existing security investments.

The organization is currently on the lookout for a Senior Cyber Security Engineer to join a growing security function, stepping into a role with real ownership from day one. The ideal candidate will bring deep, practical experience across SASE/SSE, vulnerability management, and EDR, working independently across a modern security stack including Zscaler/Netskope, Microsoft Purview/Defender/Sentinel, and Rapid7, while engaging directly with customers and stakeholders with minimal onboarding.

Responsibilities:

• 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

Skills/Must Have:

• 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

Benefits:

• 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

Location:

• Liverpool Street, London
• Hybrid, 2–4 days per week in office

Salary:
