Specifications include, but are not limited to: This Request for Proposals (“RFP”) seeks to qualified search firms to provide staffing services for a variety of positions with the City of Philadelphia (“City”) on an on-call basis. Most recruitment activities for the City are handled by the hiring departments with support from the Office of Human Resources (“OHR”) and the Office of the Chief Administrative Officer (“CAO”). However, for senior management level (i.e., Commissioner, Officer, Executive Director) or other hard-to-fill positions (i.e., engineers, technical professionals), the use of qualified search firms can assist in efficiently and effectively finding talent, decreasing time to hire, and mitigating operational impacts of a vacancy.
