IT Security Engineer

Job Title: IT Security Engineer

Location: London

Role purpose

The IT Security Engineer will be responsible for supporting the implementation, operation, and continuous improvement of Verne’s security operations capability across all regions, covering corporate IT environments and the interfaces to OT environments that support data centre operations. Based in the UK headquarters, this role will work closely with Compliance, Operations, IT, the Head of Information Security, and Verne’s SOC to help ensure that security controls are effective, practical, well documented, and capable of meeting both ISO-aligned requirements and demanding customer audit expectations.

This is a senior individual contributor role with significant responsibility for the day-to-day operation of security monitoring, incident handling, security tooling, and technical control implementation across the organisation. The role also has operational ownership of core security platforms and appliances, including their technical architecture, configuration, testing, change control, and ongoing reliability across IT environments and controlled IT/OT boundaries.

This role operates within Verne’s broader information security framework and works closely with the Head of Information Security, who retains overall responsibility for enterprise security strategy, policy, and programme leadership.

Key responsibilities

• Support the implementation, operation, and continuous improvement of Verne’s security operations activities across all regions.
• Define, maintain, and improve the technical architecture and deployment approach for operational security platforms and appliances across the organisation, in alignment with Verne’s wider information security framework.
• Own the administration, configuration, maintenance, and controlled change of key security platforms and appliances, including firewall infrastructure, centralised management platforms, SIEM, and related monitoring and protection technologies.

Support the maintenance of operational security records and evidence required to meet IMS requirements, ISO-aligned controls, and customer audit expectations.

Work with Compliance to ensure that security operations activities, records, and controls align with IMS requirements and support internal and external audits.

Support customer audits, due diligence requests, control walkthroughs, and remediation programmes related to cyber security and operational security controls.

Support recurring reporting, dashboards, service trends, and control metrics for review by relevant stakeholders.

Work within formal ticketing, incident, and change control processes, ensuring actions are properly logged, traceable, and closed out.

Collaborate with site and central teams to ensure that security requirements remain practical and effective in critical operational environments and contribute to good operational discipline across the business.

The role will involve occasional travel to Verne sites and offices in support of audits, incident response, control reviews, operational changes, and project needs.

Some out-of-hours support will be needed for incident response, security investigations, planned changes, or critical operational activities.

Candidate profile

The successful candidate will be disciplined, analytical, and well organised, with a strong sense of ownership and follow-through. They must be motivated and accustomed to working in a team environment, while also being capable of handling sensitive matters with discretion and good judgement. This role requires an individual who is comfortable operating in controlled environments, who values documentation and evidence, and who can balance security, practicality, and auditability in a growing multi-region business. The individual must be capable of maintaining a high operational standard across security platforms, security monitoring, and controlled IT/OT boundaries.

• Exposure to OT, ICS, or other operationally critical environments.
• Experience with EDR, vulnerability scanning, or other security monitoring platforms in addition to SIEM.
• Experience supporting customer security questionnaires, audits, or due diligence processes.
• Experience producing KPI reporting, dashboards, or trend analysis, including the use of tools such as Power BI.
• Basic scripting, automation, or data-handling skills to support reporting and operational efficiency.
