The Opportunity

We're supporting a major UK infrastructure organisation at a pivotal point in a long-term investment programme.

Coordinate closely with:
Project and development teams
External suppliers
Establish strong supplier relationships and effective communication channels
Support delivery of NEC-based contracts (including design contracts)
Advise stakeholders on procurement approach and contract strategy
Build a repeatable procurement process for long-term programme delivery
