You'll bring:

-Strong experience in commercial governance, contract administration and change control.

-A sound understanding of commercial risk management, forecasting and financial performance.

-Experience leading complex commercial negotiations, contract variations and dispute resolution.

-The ability to interpret contract terms and provide clear, pragmatic commercial advice.

-Experience managing a large contract portfolio or multiple contracts within a complex operational environment.

-Strong stakeholder management skills, with the ability to engage confidently with senior leaders and clients.

-Experience leading, mentoring and developing Commercial Managers and Assistant Commercial Managers.

-Professional membership of a recognised commercial institution, or active progress towards qualification.

-The capability to provide guidance across technical commercial and RICS-related FM disciplines.

Why Apply?This is an opportunity to take ownership of the commercial agenda across a high-profile government portfolio worth circa £70m, leading a talented commercial team while working alongside senior stakeholders to deliver strong commercial, contractual and client outcomes.
