Are you ready to apply your security expertise to projects that really matter? Join a fast-growing digital consultancy delivering some of the UK’s most innovative work across Defence and National Security. With long-term programmes already in place, you’ll have the chance to work at the forefront of security monitoring and engineering for critical systems.

A Security Engineer is required to support high-impact programmes in secure environments. Working closely with the lead Security Architect, you’ll play a key role in deploying and configuring modern security tooling across complex platforms. This is a great opportunity for someone who enjoys hands-on engineering, improving SOC effectiveness, and shaping threat detection capabilities at scale.

What you’ll be doing

• Deploying and configuring security tools including SIEM, vulnerability scanning and endpoint monitoring
• Developing use cases, alerts, and dashboards to support active threat detection
• Writing and maintaining SOC playbooks and triage workflows
• Performing 2nd line security monitoring, incident triage and investigation
• Supporting security assurance activities and documentation across the programme lifecycle
• Working with cross-functional teams in a high-assurance, cloud-native environment

What you’ll bring

• Strong experience configuring and optimising SIEM tooling (e.g. Splunk, Elastic)
• Proven ability to create use cases, alerts, and visualisations for SOC effectiveness
• Hands-on experience writing playbooks and operational processes for security events
• A current DV (Developed Vetting) clearance (this is a higher level than security clearance)
• Willingness to be on site in Farnborough 2 days per week

Bonus if you have:

• Familiarity with MOD policy (e.g. JSP 440, JSP 604) and assurance practices
• Experience with CI/CD tools, Kubernetes and modern DevSecOps approaches
• Knowledge of Tenable/Nessus, vulnerability management and SOC operations
• Exposure to working within a defence, security or mission-critical environment

Looking for a role where your expertise has real-world impact in a secure, fast-paced programme?
