This position plays a key role in managing the full lifecycle of contracts—from proposal development through negotiation, award, (including award challenges), administration, closeout, and potential, post-contract audit—while ensuring compliance with regulatory and contractual requirements to include the Federal Acquisition Regulations (i.e., FAR) and the Defense Federal Acquisition Regulation Supplement (DFARS). As part of a small‑business federal contracting environment, this role collaborates closely with technical staff, project managers, business development, accounting, legal/compliance (when warranted), prime contractors, and subcontractors to deliver responsive, compliant, and effective contract support.
