Cyber Security Operations & CTI Lead
Location: Remote, UK-based
Full Time, Permanent
Band B2 | £77,000 – £90,000 per annum DOE
Overview
Serco is building out its in-house cyber security capability, and this is a rare opportunity to shape it from the ground up. Around 18 months ago we made a long-term commitment to bringing more security expertise in-house — this new role is a key part of that plan.
You'll provide senior technical leadership across Security Operations and Threat Intelligence, ensuring threats are identified, analysed, and translated into action. This is a hands-on technical role: monitoring, threat hunting, detection engineering, and incident response — strengthening how Serco detects and responds to evolving cyber threats. We're a small team with large ambitions, globalising this service, and you'll play a central role in shaping its future.
As part of this you’ll:
- Provide technical leadership across Security Operations — alert triage, investigation, and escalation — and act as senior escalation point for complex investigations
- Design, build, and evolve a new Cyber Threat Intelligence capability, integrating it into SOC workflows, detection logic, and incident response
- Analyse and track threat actors and campaigns, mapping adversary TTPs to MITRE ATT&CK and translating intelligence into detection improvements
- Develop, tune, and optimise detection rules based on threat intelligence and incident learnings
- Lead hypothesis-driven threat hunting, feeding outcomes back into detection engineering
- Lead cyber incidents end-to-end, producing high-quality incident reports with root cause analysis and lessons learned
- Author and maintain incident response playbooks and SOC/CTI processes
- Task-manage a team of analysts day-to-day, with around four direct reports as the function grows
- Participate in an on-call rota supporting incident escalations

Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What you’ll need to do the role:
We're looking for someone who has been there and done it technically — deep, hands-on experience matters more here than a long leadership track record. You'll bring:
- 7+ years' experience in cyber security roles, in-house or within an MSSP
- Strong experience within a SOC environment, including incident response end-to-end
- Proven experience building or integrating a Cyber Threat Intelligence function
- Strong knowledge of SIEM, EDR, and SOAR tooling, and the MITRE ATT&CK framework
- Demonstrated detection engineering and intelligence-led threat hunting experience
- Clear communication skills, technical and non-technical, and the ability to operate under pressure during incidents
You'll need to be eligible for BPSS clearance.
Desirable
- CISSP
- Relevant SANS certifications (e.g. SEC503, FOR572)
- Relevant Microsoft certifications (e.g. SC200)
