What is this role?

This is a Service Delivery Manager role supporting one of Defence’s most critical digital communications services.

High Grade Messaging (HGM) provides secure, 24/7 messaging services to a select customer base in the UK and overseas. The service is currently transitioning to a new Military Messaging capability, making this a key moment to join.

Why this role matters

Secure messaging underpins Defence operations.

In this role, you’ll:

  • Ensure vital communications services remain resilient and available

  • Protect highly sensitive information

  • Support the transition from HGM to the next‑generation Military Messaging service

This is operational service delivery with national‑level importance.

What you’ll be responsible for

As Service Delivery Manager, you will:

  • Lead delivery of a 24/7/365 secure messaging service

  • Ensure service performance meets agreed SLAs

  • Manage incidents, service resilience and continuous improvement

  • Lead and motivate operational teams in a fast‑paced environment

  • Act as Assistant Security Officer, ensuring security compliance

  • Oversee service transition to the new Military Messaging platform

  • Work closely with senior stakeholders and specialist partners

You’ll balance day‑to‑day operational delivery with longer‑term service improvement.

These requirements are essential to protect sensitive Defence operations.
