Who We Are:
At CACI Information Intelligence Group (IIG), we solve some of the UK's most complex and mission-critical challenges through technology. We're a specialist software, data and technology consultancy that designs and delivers cutting-edge solutions across AI, cloud, software engineering, cyber security, data platforms, automation and digital transformation. Our teams support customers operating at the heart of Government, National Security, Defence, Critical National Infrastructure and Law Enforcement.
As demand for our expertise continues to grow, we're looking for a Deputy Security Controller to join our team.
The Opportunity:
As Deputy Security Controller, you will play a key role in the day-to-day running of IIG’s security function. Working closely with the Security Controller, you’ll help maintain security compliance and keep security operations running smoothly. As a senior member of a small team, you’ll take ownership of delegated security activities, coordinate priorities and provide day-to-day guidance and support to the Security Administrator. You’ll also deputise for the Security Controller when required, providing continuity and making decisions within your delegated responsibilities.
This is a role that combines responsibility with practical delivery. Alongside overseeing security processes and monitoring compliance, you’ll stay actively involved in the operational detail, bringing a flexible, hands-on approach to changing demands. Teamwork is central to how we operate. While you’ll have your own areas of responsibility, you’ll also support the wider security function wherever needed—from vetting at all clearance levels to visitor management, escorting and general security activities. Responsibilities will Include:
Supporting the management and maintenance of site security arrangements and procedures. Deputising for the Security Controller when required, maintaining continuity of day-to-day security operations and making decisions within agreed delegated authority. Assisting with monitoring compliance with UK Government security requirements and customer security obligations. Coordinate and oversee personnel security and vetting activities across all clearance levels, including applications, renewals and transfers. Identify and escalate security risks, compliance gaps and operational concerns Support physical security, access control and security pass arrangements. Assist with security audits, inspections, reviews and incident management. Provide guidance and day-to-day support to the Security Administrator, helping prioritise workloads and ensure tasks are completed.
The Fit:
The successful candidate will have previous experience working in a security or compliance role within a highly regulated environment. This will include hands on experience supporting personnel security and vetting administration, including maintaining records and tracking applications or clearance-related actions. As a key member within a small security team, you will be proactive, collaborative with a flexible approach and a willingness to undertake routine administration and hands-on security activities alongside more senior responsibilities.
Due to the industries we work in, we require all our team to be able to obtain security clearance. To qualify for this, you must be a British passport holder and have lived permanently in the UK for the last 10 years.
