Senior Subcontract Manager
Be at the forefront of transforming British Army training.

About us

At OMNIA® Training, we've brought together some of the UK's most innovative defence training organisations under one powerful mission: to transform the British Army's training system and create the best-trained Army in the world. OMNIA are redefining the British Army's collective training. To do that, we are looking for the best and brightest minds from across the UK. We are backed by British innovation and powered by world-class experts, like you. OMNIA is at the heart of the UK's bold Land Industrial Strategy.

The role

This is more than a job - it's a mission. You will be part of a high-impact, collaborative environment, where we expect everyone to live the values and standards of the British Army. Every person in our team plays a critical role in delivering OMNIA's vision; designing, delivering, and transforming collective training so the British Army is ready to fight and win.

You'll work in a matrix organisation and report operationally through OMNIA Training and functionally through the Raytheon UK Commercial team. Ultimately, you'll work for the British Army, championing innovation, and helping shape the future of military training.

Raytheon UK is seeking a highly experienced and strategic Senior Subcontracts Manager to manage large sized subcontracting projects and help lead and evolve our subcontracting function on the British Army Collective Training Transformation Programme (CTTP). This M5-level role is ideal for a commercially astute leader with deep expertise in subcontract management, contract negotiation, and supplier performance, who can drive operational excellence and influence across the mission area or major programme.

Key Responsibilities

• Own the execution of long-term subcontracting strategies (3+ years) while delivering short- to medium-term tactical plans (1-2 years) aligned with business goals.
• Manage Subcontractors / Suppliers with large sized contracts (£100m+) with minimal to no oversight, ensuring alignment with business objectives.
• Lead a team of experienced professionals in managing complex subcontract portfolios across multiple sites, geographies, or customer domains.
• Coach, review, and delegate work to lower-level professionals, supporting their development and ensuring high-quality delivery.
• Develop and implement new processes, standards, and operational plans to enhance subcontractor performance and compliance.
• Solve complex, undefined problems through detailed analysis, stakeholder engagement, and strategic decision-making.
• Influence internal and external stakeholders on subcontracting policies, practices, and procedures.
• Manage budgetary elements and contribute to P&L accountability within the subcontracting function.
• Oversee supplier selection, supplier negotiation, contract execution, and ongoing performance management.

Who we are looking for

We're after individuals who want to serve. You'll have a mission focus, and the enthusiasm and drive to 'get things done'. You'll want to work in collaboration with other defence training organisations, and the British Army. You won't let bureaucracy get in the way of what needs to be done, you'll learn lessons and share these lessons across the team. You won't necessarily have a military background, but you'll understand what it means to serve and to put the mission first.

• A university degree (preferably in a STEM or business-related field) and a minimum of 10 years of relevant experience in subcontract management, or an advanced degree with at least 7 years of experience.
• Expert knowledge of subcontract management, supplier engagement, and contract execution.
• Proven leadership in managing subcontracting operations within a complex, regulated, or defence-related environment.
• Strong commercial acumen and negotiation skills, with a track record of delivering value through supplier relationships.
• Excellent communication and influencing skills, with the ability to engage stakeholders across functions and levels.
• Experience in hiring, developing, and managing high-performing teams.
• Eligibility to obtain UK Security Clearance (SC level) is essential.

• Experience operating in joint or matrixed teams
• Ability to communicate across military and industry partners
• Focused on outcomes, delivery, and operational excellence
