Senior SOC Engineer

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

In support of our continued UK growth, we are seeking a Senior SOC Engineer to join our Security Operations team. This role presents a great opportunity to shape the direction of a modern, technology focused SOC that values engineering excellence, deep technical capability and a culture of innovation. You will work with a broad and diverse customer base that relies on Nomios to deliver meaningful and effective security outcomes.

Your role as Senior SOC Engineer

As a Senior SOC Engineer at Nomios, you'll lead the design, deployment, and ongoing improvement of the technologies that underpin our SOC, including SIEM, XDR, SOAR, scripting, and automation. From building custom log parsers and response workflows to developing platform architecture, you’ll drive meaningful enhancements to our detection and response capabilities.

You’ll play a central role in security orchestration and automation, helping reduce time to detect and respond by refining playbooks and building intelligent workflows. You’ll also lead customer onboarding in collaboration with SOC Operations, ensuring secure, efficient deployments aligned with our model. Working directly with SIEM/XDR platforms and custom tooling, you’ll have access to dedicated SOC infrastructure: lab environments for malware analysis, detection testing, threat intel development, and proof of concepts.

You’ll be part of a high-performing team that values hands-on expertise, technical leadership, and continuous growth. Our SOC culture is built by engineers who’ve progressed through roles in security operations, threat intelligence, and engineering. You’ll benefit from cyber ranges, training labs, and the freedom to shape your development path.

As part of a leading MSSP, you'll gain exposure to a wide range of industries, from government and defence to healthcare, telecoms, legal, and manufacturing, broadening your knowledge of real-world security practices. Whether you’re a seasoned Senior Engineer or ready to step up, this role offers ownership, impact, and the chance to help shape the mission.
