• Evaluate subcontractor proposals, negotiate pricing and terms, and prepare award documentation in accordance with CPSR and company procedures.
• Collaborate with internal stakeholders to ensure timely pre-award reviews, pricing validation, and risk assessment.
• Manage subcontract administration through all phases-execution, amendments, performance monitoring, and closeout.
• Partner with Program Management, Finance, and Contracts teams to align negotiation strategy and minimize risk exposure.
• Maintain accurate subcontract tracking records and prepare reports to support internal audits or leadership requests.
• Lead and train lower-level Subcontract Administrators and internal stakeholders on procurement best practices and compliance.
• Foster positive working relationships with internal teams and subcontractors to ensure seamless communication and issue resolution.
  
  

Requirements
