  • Develop the acquisition strategy.
  • Translate technical requirements into executable packages.
  • Conduct and document market research: Identify capable sources, assess competition, validate supplier eligibility and responsibility, and support make-or-buy, commerciality, and single- or sole-source determinations when applicable.
  • Manage solicitations and source selection.
• Proposal Analysis, Negotiation, and Award:
  • Perform cost and price analysis.
  • Lead negotiations within delegated authority.
  • Document the business decision.
  • Establish the appropriate subcontracting arrangement.
  • Ensure award readiness.
• Post-Award Administration and Supplier Performance:

• Compliance, Records, and Business Leadership:
  • Interpret and apply requirements.
  • Maintain CPSR-ready and audit-ready files.
  • Protect sensitive information.
  • Support reviews and corrective actions.
  • Improve execution.

The successful candidate will:

• Exercise sound independent judgment and know when a matter requires management, legal, compliance, or customer escalation.
• Manage multiple high-priority actions and short deadlines without sacrificing compliance, documentation quality, or business judgment.
• Communicate contractual risk clearly and convert technical or program requirements into specific, enforceable subcontract language.
• Be organized, responsive, detail-oriented, and effective in a collaborative, matrixed program environment.
• Understand how subcontract terms allocate cost, schedule, technical, and performance risk and apply that understanding during negotiations.
