Working with a leading Tier 1/2 builder on a significant defence production and demonstration facility, you will join an established commercial team, working closely with the Commercial Manager and two other Contract Administrators.

This is a hands-on, site-based role suited to a commercially minded Contract Administrator who enjoys working through subcontractor and client variations, managing contractual documentation and maintaining strong relationships with key project stakeholders.

- Strong experience managing subcontractor and client variations.
- Confident communicating with clients, subcontractors and internal project stakeholders.

- Previous Tier 1 construction and/or defence project experience will be highly regarded.
