Principal Subcontract Specialist 

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 & Subcontract Management 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 capable and experienced Principal Subcontract Specialist to support and lead key subcontracting activities across the British Army Collective Training Transformation Programme (CTTP). This P3-level role is ideal for a professional with good knowledge of subcontract management, who can work independently, communicate with stakeholders, and drive operational improvements & performance of our suppliers supporting British Army Training.

Key Responsibilities:

  • Manage Subcontractors / Suppliers with moderately sized contracts (10 - 40m) with minimal oversight, ensuring alignment with business objectives.
  • Manage small projects or subcontracting processes with autonomy and accountability for delivery.
  • Apply advanced knowledge of subcontracting practices to solve difficult and occasionally complex problems across multiple work areas.
  • Management and negotiation of contracts, non-disclosure agreements and terms and conditions.
  • Provide coaching and guidance to junior professionals, ensuring quality and consistency in subcontract execution.
  • Communicate effectively with internal teams and external stakeholders, including suppliers and customers, to align on policies, practices, and procedures.
  • Influence operational decisions and contribute to the development and enhancement of subcontracting processes and systems.
  • Deliver day-to-day objectives that have a significant impact on operational results within the programme.

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) or equivalent experience.
  • Practical knowledge of subcontract management, supplier engagement, and contract execution.
  • Strong analytical, and problem-solving skills, with the ability to operate mostly independently, engage and communicate across functions and make informed decisions.
  • Experience in managing subcontracting activities and contributing to planning.
  • Experience in coaching & guiding junior team members.
  • Good communication and stakeholder management skills, with the ability to influence at an operational level.
  • 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.
