Commercial Strategist

Amentum is a global leader in engineering, project and programme management and solutions integration. Founded on programme, project, and engineering experience, along with deep‑seeded specialist capabilities, Amentum has become a recognised delivery partner across major UK Government and commercial programmes.

Our Defence & Security business supports the UK Ministry of Defence in the delivery of their capability and objectives via a host of frameworks. The work we do is of international importance in ensuring our National Security and that of our allies, something our team are proud to support.

People are our greatest asset, and we offer a competitive package to retain and attract the best talent. In addition to the benefits you would expect, UK employees also receive free single medical cover and digital GP service, family‑friendly benefits such as enhanced parental leave pay and free membership of employee assistance and parental programmes, plus reimbursement towards relevant professional development and memberships.

We also give back to our communities through our programmes which incorporate matched‑funding, paid volunteering time and charitable donations.

We are seeking a highly capable, collaborative and adaptable individual to support the successful shaping, set‑up and mobilisation of complex bids, projects and programmes. This role is focused on the front end of programme development, helping define the governance, delivery model, procurement strategy, commercial approach, contracting structure and mobilisation arrangements required for successful delivery. The role supports both bid / pursuit activity and live project and programme environments, helping shape the conditions for successful delivery from the outset.

It is suited to a broad senior programme professional who is comfortable working across commercial, contractual and programme disciplines, but is not defined by any single function. Its value lies in helping programmes get set up coherently, with the right structures, behaviours, controls and interfaces in place from the outset, so that teams can move into delivery with greater clarity and confidence.

The successful candidate will work closely with senior programme leadership, clients and key functional teams, providing strategic direction, judgement and practical support across programme initiation, set‑up and delivery readiness. The ideal candidate will combine strategic thinking with practical delivery judgement, be comfortable operating in ambiguity, and be able to translate strategic objectives into workable programme, procurement and contractual arrangements. They will be confident turning their hand to a broad range of front‑end programme activities and bringing structure, coherence and momentum to complex environments.

• Advise on contracting strategy and the use of contractual and commercial mechanisms to promote the right behaviours across client, supply chain and stakeholder environments.
• Help establish the delivery model and programme structure, including organisational interfaces, design of key teams and practical mobilisation arrangements.
• Support programme mobilisation, ensuring that governance, roles, interfaces, controls and commercial arrangements are sufficiently developed to enable transition into delivery.
• Provide strategic support on bids and tender processes, helping teams shape approaches, navigate procurement activity and maintain alignment between commercial, governance and delivery requirements.
• Provide contract management…
