Built on Integrity. Ready for the Mission.

At Tamayo Federal Solutions (TFS), we believe great missions are accomplished by great people—not just the most experienced, but those with the right mindset, integrity, and drive to grow. TFS delivers high-impact, mission-focused solutions for federal customers nationwide. We are growing quickly and seeking motivated professionals who are ready to grow with us.

Your Mission

Support TFS corporate operations and our federal customer base by providing administrative operations, human resources, and facility security support — with primary ownership of new hire onboarding, recruiting coordination, personnel security administration, and expense report processing, while serving as Assistant Facility Security Officer (AFSO) under the direction of the FSO.

What You’ll Do

In this role, you will keep daily business operations running smoothly from our Virginia Beach office within a cleared facility, moving between hands-on administrative execution and program-level coordination across HR, Finance, IT, Facilities, and Security. The position requires discretion, accuracy, and the ability to manage confidential personnel and security information under government deadlines.

· Own the end-to-end new hire onboarding process from offer acceptance through the first 30 days, including offer letters, new hire paperwork, I-9 and E-Verify documentation, and background check completion (if applicable).

· Coordinate start dates, first-day logistics, workspace assignments, badge issuance, and equipment and system access with IT, Facilities, and Security; and deliver new hire orientation.

· Post and maintain open requisitions across the applicant tracking system (ATS), job boards, and university and veteran hiring channels; screen applications, schedule interviews across multiple calendars, and manage candidate communication and status updates.

· Support offer preparation, reference checks, and pre-employment and clearance-related pre-screening; maintain recruiting metrics and reporting (time-to-fill, pipeline status, source of hire) and applicant flow recordkeeping for OFCCP/EEO compliance.

· Serve as Assistant FSO in compliance with NISPOM (32 CFR Part 117), DCSA guidance, and contract security requirements (DD Form 254): process personnel security clearance actions in e-QIP, submit and track investigations and periodic reinvestigations, and maintain records in DISS.

· Administer physical access and visit control (visitor logs, classified visit authorizations); conduct initial, annual refresher, foreign travel, and termination briefings; and support self-inspections, DCSA vulnerability assessments, incident reporting, classified document accountability, and insider threat program administration.

· Review, code, and process employee expense reports for accuracy, policy compliance, and proper allocation to projects, cost centers, and contracts; administer the corporate card program; track travel authorizations against company policy and applicable FTR/JTR rates; and coordinate with accounting on month-end close, accruals, and reimbursement cycles.

· Provide general administrative and operations support — calendar and meeting coordination, correspondence and document preparation, records and filing systems with appropriate retention and confidentiality standards, office supplies and vendor management, SOP development and process improvement, and coordination of company events and all-hands meetings.
