Job description

Security Engineer - MOD / Defence / High Security Clearance

Farnborough | Hybrid 3 days p/week on site
£75-80k + bonus and benefits
High-level UK Security Clearance required

Are you a Security Engineer with experience across privileged access management, identity security or enterprise security tooling?

This is a hands-on security engineering role working within a highly secure Defence and National Security environment. You'll maintain and improve security platforms controlling privileged access, credentials and administrative activity across critical infrastructure.

There is also a requirement within the team for Elastic SIEM capability, so if you have strong Elastic experience alongside your security engineering background, that would also be relevant.

The role

You’ll work across identity, privileged access and wider security infrastructure, including:

• Managing passwords, SSH keys, API keys and privileged credentials.
• Configuring and troubleshooting automated password and credential rotation.
• Running discovery scans across Active Directory and network environments.
• Managing RBAC, permissions and user/group access.
• Monitoring privileged sessions and investigating failed authentication activity.
• Maintaining, patching and upgrading security platforms.
• Reviewing audit logs and integrating security events with SIEM tooling.
• Troubleshooting firewalls, load balancers and connectivity issues.

Key experience

• Hands-on Security Engineering within complex environments.
• Privileged Access Management (PAM) or identity security solutions.
• Active Directory, identity providers, privileged and service accounts.
• Vulnerability scanning, EDR or SIEM tooling.
• Elastic SIEM experience would be a strong advantage.
• Understanding of RBAC, credential management and security monitoring.

Experience with DevSecOps, CI/CD, ATT&CK or MOD security environments would also be useful.

There is a great corporate benefits package.

If your background is in PAM, identity security, Elastic SIEM or hands‑on security engineering, this is an opportunity to work on complex systems where security has a direct operational impact.
