• Provide timely updates to Business Development, Recruiting and Operations regarding sourcing progress, candidate risks, documentation gaps, and potential alternatives so proposal deadlines can be met. 

• Monitor RFI and early-stage opportunity activity to develop candidate options before an RFP is released, updating the pipeline as requirements change. 

• As capacity allows, support open positions on active contracts through sourcing, initial outreach, screening coordination and handoff to the assigned recruiter or hiring team. 

• Coordinate candidate clearance verification through authorized company security or FSO processes; document the verified status and eligibility information relevant to the opportunity. 

• Assist with formatting candidate resumes for proposal submissions, following solicitation instructions and required templates while preserving accuracy and ensuring all experience is supported by the candidate’s materials. 

Required Qualifications
