  • Support the commercial and operations team’s business improvement initiatives.
  • Develop and execute effective commercial strategies on bids, including key financial metrics, including reviewing AECOM bid models for compliance with commercial objectives.
  • Enforce compliance with governance requirements, support project teams with submissions requiring further approvals and ensure close out of governance actions, escalating to the Commercial Director, as required.
  • Co-ordinate with legal counsel on commercial matters (e.g. contracts, warranties, PCG’s etc). Provide point of reference for terms and conditions negotiations and support with these negotiations.
