Job description

The Challenge

Do you want to join the 2021 Government Security team of the year and be part of our Gold Standard security service?

The Ministry of Defence Guard Service (MGS) provides high quality security services at approximately 100 MOD sites across Great Britain. The MGS has guarded the Defence Estate for over 25 years including high profile locations such as MOD Main Building in London and His Majesty’s Naval Bases at Portsmouth, Devonport and the Clyde. We provide access control, military working dogs, control room operations and other security services. We play a vital role supporting the Defence Mission and work to protect the defence estate and personnel from crime, terrorism, espionage and sabotage threats.

The MGS is part of the Defence Infrastructure Organisation (DIO) and employs over 2,500 staff. MGS Officers are often the first point of contact with the MOD for employees, visitors and contractors and we pride ourselves on our professional, customer-focused culture.

All our Security Officers are required to have excellent customer service skills and must be willing to go above and beyond to support security operations across the defence estate. Due to the high profile and strategic locations of the sites we guard, it is essential our Security Officers have a strong work ethic, are able to work as part of a team, are observant to threats and are capable to challenge and de-escalate difficult situations if required. We also require our Security Officers to have good written and verbal communication skills. Our Officers must have resilience and remain positive and friendly in all weather conditions and on all occasions.

We provide our staff with a market leading salary, excellent sickness benefits, together with a defined benefit civil service pension. Free full uniform will be provided.

We are a growing organisation with opportunities for good quality staff to progress their security careers.

The MGS holds the Committed to Equality Gold Standard and we positively encourage applications from all under-represented communities and from all types of working backgrounds.
