(FTC) Programme Support Manager

Role Overview

Thorn SDS is a niche Managed Service Provider, who is committed to enabling technology organisations and professionals to thrive within the Space, Defence and Security sectors.

We are currently recruiting for a (FTC) Programme Support Manager to join the Most Stressed Use Cases (MSUC) team at a critical moment in the programme’s life-cycle. We’re seeking a highly capable and motivated P3M
professional to play a central role in shaping and evidencing a Category A Outline Business Case (OBC).

About the Role

This role places you at the heart of one of Defence’s most strategically important digital and satellite communications programmes. Working predominantly High-Side, you will collaborate closely with stakeholders across MOD, Front Line Commands, Other Government Departments, and user communities to develop, assure, and present robust evidence that informs senior decision making.

If you thrive in complex, fast-moving environments and enjoy working in small, mission-focused teams, this is an opportunity to make a real impact.

Key Responsibilities

• Develop, collate, and assure evidence required to support a CAT A OBC, working closely with MSUC leads and programme stakeholders.


• Engage user groups across Defence to capture use cases, requirements, and supporting data.


• Deliver high-quality P3M artefacts, including schedule, risk, dependencies, and milestone evidence, to support critical approvals and decision points.


• Provide a clear, transparent picture of programme maturity and risks to decision makers navigating multiple competing priorities.


• Work flexibly within a small, high-performing team—taking on a variety of tasks and contributing wherever needed to meet programme objectives.

Essential Skills & Experience

• Current security clearance


• Strong P3M expertise, including schedule and risk management


• Demonstrated CAT A approvals experience


• Ability to capture, review, analyse, and assure evidence for an OBC


• Excellent stakeholder management and relationship-building skills


• Clear and confident communication, fluent in English


• Strong facilitation abilities


• Willingness and ability to work predominantly High-Side, with regular onsite presence

Desirable Experience

• Previous experience working within a Defence environment


• Exposure to requirements development and associated activities


• Understanding of satellite communications or wider defence communications


• Current access to MODNET and MOD-issued hardware

What We’re Looking For

A proactive, adaptable professional with a can-do attitude who enjoys operating in a dynamic environment. You will be comfortable taking ownership, thinking critically, and contributing across a range of tasks to ensure the successful delivery of the OBC.
