Founded in 1989, SOSi is among the largest private, founder-owned technology and services integrators in the defense and government services industry. We deliver tailored solutions, tested leadership, and trusted results to enable national security missions worldwide. Ready to be the heartbeat of an HR team that moves fast, cares deeply, and makes a real difference for every employee — from day one? At SOSi, our people are our mission. As our HR Administrator, you'll shape how every new hire experiences joining this company, champion the programs that keep our team engaged and recognized and be the trusted go-to resource employees turn to when it matters most. We're a team that embraces smarter ways of working: we expect you to bring curiosity and confidence in applying AI tools to streamline the manual, repetitive work that has historically defined HR administration — so you can spend more of your energy on the human side of HR. If you're organized, energized by variety, love being the person who makes things happen, and are excited about working at the intersection of people and technology, this role was built for you. What you'll do Hit the ground running managing our full recruiting administration — posting and monitoring requisitions in the ATS, generating offer letters, and owning pre-employment documentation with precision. You'll leverage AI-assisted tools to accelerate drafting, tracking, and reporting across these workflows, cutting cycle times without sacrificing accuracy. You'll be the architect of an onboarding experience that sets new hires up for success: guiding employees through the SOSi SPARK program, leading orientation sessions and making sure every piece of compliance documentation — including I-9 and E-Verify — is buttoned up. Beyond onboarding, you'll keep the engine running across a wide range of HR operations — and you'll look for every opportunity to make those operations faster and more consistent through intelligent automation: * Maintain
