Senior Security Engineering Consultant

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 Security Engineering Consultant 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 work across a range of technologies and engagements, from SOAR and SIEM implementation through to vulnerability management, exposure management, and process automation.

Your role as Senior Security Engineering Consultant

The Security Engineering Consultant role sits within the Security Operations Team, working directly with the Nomios SOC Engineering team.

This is a senior, customer-facing Professional Services role within our Security Engineering function, focused on detection engineering and automation. You will lead the design and delivery of detection and response capabilities across SIEM, XDR and SOAR platforms. This includes building detection rules, developing automations, and creating operational playbooks that support effective SOC outcomes.

A key aspect of the role is ownership of the detection as code approach, ensuring detections and automations are developed, structured and delivered in a consistent and scalable way. Working directly with customers, you will define detection strategies, design use cases aligned to MITRE ATT&CK, and guide improvements in visibility, coverage and response maturity. You will work closely with platform onboarding and engineering teams, supplementing them with specialist expertise in detection engineering and automation, rather than focusing on platform deployment itself.

The role combines hands-on engineering with advisory responsibilities, with a clear focus on delivering high-quality outcomes and enabling customers to operate and evolve their detection capabilities.

Responsibilities

Key responsibilities of the role include:

Deliver

• Design and deliver detection rulesets across SIEM and XDR platforms

• Develop and tune detection logic using KQL or equivalent query languages

• Design detection use cases aligned to MITRE ATT&CK and real-world attack techniques

• Map customer log sources to detection use cases to assess coverage and identify gaps

• Design and implement SOAR automations, integrations and response workflows

• Develop and document customer incident response playbooks aligned to detection outputs

• Translate threat intelligence and operational learnings into improved detections and automations

• Deliver detection as code pipelines, including structured use case development and versioning approaches

• Produce clear technical and customer-facing deliverables, including detection strategies, use case catalogues and coverage assessments

Collaborate

• Work directly with customers as a trusted technical consultant

• Lead workshops covering detection engineering, use case design and SOC maturity

• Guide customers on improving detection coverage and aligning to MITRE ATT&CK

• Clearly explain detection strategies, gaps and recommendations to both technical and non-technical stakeholders

• Work closely with platform onboarding and engineering teams to ensure smooth integration of delivered detections and automations

• Support SOC teams by ensuring delivered outputs are practical, usable and aligned to operational workflows

Improve

• Contribute to the continuous evolution of detection use cases, playbooks and automation patterns

• Support development of reusable detection content and delivery standards

• Contribute to lab work, testing and validation of detection approaches

• Identify gaps in telemetry, logging and enrichment, and provide recommendations to strengthen detection outcomes
