Job Description:

Senior Security Engineering Consultant (Remote)

Region: London and South East, Remote/Home working.

Are you an experienced cyber professional from a military or Defence background looking to step into a more consultative, project‑led role? We’re supporting a rapidly growing cyber security organisation that is actively investing in ex‑military talent and building a high‑performing Security Operations capability. This role is ideal for someone who has already transitioned (or is close to transitioning) and wants to move into a client‑facing, engineering‑focused consultancy position.

This is not a traditional SOC role. You’ll work across a range of customer environments, helping design, build, and improve Security Operations capabilities—from SIEM and SOAR implementations through to automation, detection engineering, and cloud security assessments. Roughly 50% project delivery (client‑facing consultancy) and 50% internal engineering, innovation, and capability development. A remote role with occasional travel to the South East office.

You do not need experience with every commercial tool—training is provided. This role suits either ex‑military candidates who have already gained some commercial or advanced technical exposure, or service leavers with strong cyber/SOC experience and the confidence to step into a consultative role.

What You’ll Be Doing

  • Delivering security engineering projects across SIEM, SOAR, and XDR platforms
  • Designing and building automation playbooks and integrations
  • Conducting cloud (Azure‑focused) security health checks
  • Developing detection rules, log parsing, and correlation logic
  • Supporting vulnerability and exposure management programmes
  • Working closely with internal engineering teams to improve tooling and processes
  • Acting as a trusted technical advisor to customers

Essential Qualifications

  • Experience working in a SOC or CDOC (Cyber Defence Operations Centre) environment
  • Strong understanding of security monitoring, incident response and threat behaviours (e.g. MITRE ATT&CK)
  • Hands‑on experience with at least one SIEM / SOAR / XDR platform
  • Ability to take a problem and engineer a solution end‑to‑end
  • Strong communication skills and ability to engage with stakeholders

Ideal but not Essential

  • Experience with cloud security (Azure preferred)
  • Exposure to automation or scripting (e.g. Python, APIs)
  • Experience in advisory, design, or project‑based work

For Military Candidates

  • Experience at commissioned / supervisory level OR exposure to advisory or capability development work
  • Have worked in a SOC, CDOC or cyber operations environment
  • Experience analysing threats, logs, or incidents
  • Exposure to secure networks or defence systems
  • A mindset focused on problem‑solving, adaptability, and ownership

This is a fast‑paced, collaborative, people‑first culture where people genuinely support one another. Clear progression pathways, funded certifications, and structured training plans.
