The Lead SIEM Content Engineer will have full ownership of SIEM Design and content, will work with Country critical technology and have a clear scope to influence tooling, strategy and SIEM direction.
We’re looking for a Lead SIEM Engineer to take full technical ownership of SIEM capability within a high-assurance UK defence environment. You’ll shape how threats are detected, how alerts flow, and how the SOC operates at scale influencing both technology and strategy across nationally critical programmes.
If you thrive on variety, influence, and technically challenging work that matters, this role is for you.
The SIEM Content Engineer will have:
- End-to-end ownership of SIEM engineering: architecture, performance, content, and continuous improvement
- Designing and tuning SIEM systems — alerts, rules, dashboards, and reports that the SOC actually trusts
- Acting as the technical escalation point for SIEM across multiple secure programmes
- Shaping detection strategy alongside Threat Hunters, SOC leadership, and Security Architects
- Translating threat intelligence and emerging attacker techniques (TTPs) into actionable, real-world detections
- Mentoring engineers, enforcing best practice, and raising the technical bar across the SOC
If your SIEM experience covers:
- Proven SIEM engineering leadership with hands-on experience in Splunk, Microsoft Sentinel, or QRadar
- Deep understanding of attacker behaviour and how SIEM should detect it — beyond mapping frameworks
- Strong hands-on scripting and automation skills (Python, PowerShell, Regex) for tuning, enrichment, and noise reduction
- Experience operating in secure, high-pressure defence environments with senior stakeholders
- The confidence to challenge weak detections, poor data, and “we’ve always done it this way” thinking
This is your chance to lead SIEM at the cutting edge, protecting UK defence technology against state-of-the-art threats while shaping the future of the SOC.
