HR Operations Manager

Open Source Integrators is seeking a disciplined, detail-oriented HR Operations Manager to own the full scope of HR administration (excluding payroll and recruiting) and ensure operational excellence across the company.

This is a high-ownership role working closely with executive leadership. We are looking for someone who thrives on structure, precision, and follow-through - and who takes pride in executing routine responsibilities with excellence.

Our culture is built on four pillars:
Unity, Alignment, Accountability, and Trust.

We function as one team, not silos. We communicate directly. We honor commitments. We surface problems early. We follow through on commitments. We expect professional maturity and disciplined execution.

We value thoughtful, data-supported input and expect professionals to raise concerns respectfully before decisions are finalized.

We believe culture is defined by what we tolerate. High standards and humility coexist here.

If you value clarity, strong leadership alignment, and ownership, you will thrive here.
