Security Controller

About Isembard

Isembard is rebuilding industrial capacity through a connected network of factories. We bring skilled people, advanced machine tools and our own software, MasonOS, together to make precision components for aerospace, defence, energy and robotics.

The role

Isembard makes parts for aerospace and defence customers who expect their suppliers to protect people, sites and information to government standards.

The Security Controller owns personnel and physical security for our London factory, sets our vetting policy, and builds the security arrangements our defence work requires. You will give practical, remote support to other sites in our network and work across Legal, IT and operations. It is an early-stage function with a direct effect on the defence work Isembard can take on.

• Own physical security at our Southwark site, including access, visitors and secure areas.

• Set and run our personnel vetting policy, including Baseline Personnel Security Standard (BPSS) checks for new starters.

• Act as the company's point of contact for UK government security requirements, including national security vetting and facility security, as our defence work requires.

• Advise other sites in the network on security arrangements.

• Keep security policies and records current and audit-ready, and make sure people understand their responsibilities.

What you bring

• Experience in a security role at a UK defence supplier, or an equivalent government or military security background.

• Working knowledge of UK personnel security, including BPSS and national security vetting.

• Experience managing physical security for a site.

• Familiarity with UK government security requirements for defence suppliers.

• Discretion, sound judgement and clear communication.

• Useful, not essential: setting up facility security arrangements for defence work, security across several sites, or a manufacturing environment.
