Job Description

Nomios’ mission is to build a secure and connected future. Organisations across the globe depend on us to help secure and connect their digital infrastructures.

As part of our continued UK growth, we are expanding our Professional Services capability and seeking a Senior Security Engineer to deliver specialist security engineering and operations consultancy across our customer base.

This is a hands‑on technical role within the Security Operations domain, focused on helping customers improve and automate their SOC functions, tooling, and detection capabilities.

You will deliver a range of short to mid‑term customer projects, providing both technical engineering and advisory support across Security Operations tooling, architecture, and processes. Typical engagements include Azure Health Checks, SOAR and automation builds, SIEM and log source integration, parser creation, ruleset development, vulnerability management optimisation, and exposure management assessments.

Around half of your time will be spent delivering customer‑facing Professional Services projects, with the remainder focused on supporting internal engineering initiatives, labs, roadmap activities and innovation within the broader Security Operations Team.

This position suits an experienced SOC or Security Engineer who enjoys working across multiple environments and technologies, and who is comfortable engaging directly with customers as a trusted technical consultant.
