The Opportunity: For a Senior Buyer in the federal contracting and defense industry, I would shift the language away from transactional purchasing and emphasize strategic sourcing, supplier management, FAR/DFARS compliance, program support, cost control, and stakeholder partnership. Pay Range: There are a host of factors that can influence final salary including, but not limited to, geographic location, Federal Government contract labor categories and contract wage rates, relevant prior work experience, specific skills and competencies, education, and certifications.
