Location: Portsmouth

We are looking for a Security Controller to join our growing and exciting company in the Portsmouth area.

Whilst responsible for the day‑to‑day local security of the CMS2 site, specialising in the design and manufacture of atmospheric control systems for the defence industry, this role sits in the central security function of Science Group, an international science, engineering and technology (SET) business listed on the AIM stock market.

Although based at the CMS2 site with responsibility for day‑to‑day local security, this role will support the security team across several different business entities.

Whilst the role will predominantly be based in Portsmouth there will be occasional travel required to our other Science Group sites in the UK.

We are looking for an organised and process‑focused individual to support the Security function by maintaining robust security policies, procedures, records and assurance activities across the CMS2 site and wider Science Group businesses. The role will be responsible for helping to embed consistent security processes, ensuring documentation is accurate and controlled, supporting audit readiness, and promoting compliance with applicable security requirements.

• Manage and maintain security registers, logs and evidence records, including those relating to secure room assets, monthly musters, controlled items, entry passes, security aspects letters, foreign visits and security briefings.

• Administer employee, contractor and visitor access processes, including security inductions, entry passes and local access records, ensuring appropriate approvals and audit trails are retained.
• Support the Personnel Security Officer with vetting administration, including BPSS checks, clearance tracking and liaison with the central vetting team regarding SC and DV clearances. Vetting responsibilities within this role are supportive and administrative, with ownership and decision-making remaining with the Personnel Security Officer.
• Assist with the process for staff reporting changes in personal circumstances, ensuring relevant information is captured, recorded and escalated in line with established personnel security procedures.
• Coordinate IVCO requests and foreign visit processes, ensuring required information, approvals and records are managed in accordance with applicable security requirements.
• Deliver or coordinate security and travel briefings in line with current guidance, clearance levels and documented local processes.
