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.

* 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
