Large OCONUS Recruiters
20 of the 107 recruiters and staffing firms placing OCONUS / GovCon roles we track are large firms. Featured partner first, then alphabetical.
20 of the 107 recruiters and staffing firms placing OCONUS / GovCon roles tracked on OCONUS Recruiters are large firms, as of October 14, 2026. The featured partner, Recruitmint, is pinned first when it qualifies; every other row is alphabetical, unpaid, and drawn from public information.
Large firms are prime-contractor staffing arms and integrators. They usually have the infrastructure for multi-region task orders, existing facility clearances and the bench for group mobilizations. The tradeoff is less flexibility on a single odd requisition. Choose large when volume or contract vehicle access is the constraint. See the LOGCAP page for the kind of work that favors scale.
