About the Role

Perimeter is seeking an experienced and highly capable U.S. Government contracts leader to support management and negotiation of our full portfolio of government awards and agreements. This person will serve as Perimeter’s lead contracts manager and principal subject-matter expert on federal contracting, supporting the business throughout the full acquisition lifecycle—from opportunity assessment and proposal development through negotiation, award administration, modification, and closeout.

The Senior Director will negotiate directly with U.S. Government contracting personnel, prime contractors, subcontractors, and other partners while advising Perimeter’s executive, legal, finance, business development, and program teams on contractual requirements, risks, and strategy.

The successful candidate will bring deep, practical expertise in the Federal Acquisition Regulation (FAR), Defense Federal Acquisition Regulation Supplement (DFARS), and related agency requirements. They will be a strong negotiator who can protect Perimeter’s intellectual property and business interests while developing pragmatic solutions that enable successful government partnerships.
