Director of Site Services

About the role

We're seeking an exceptional operational leader to oversee all site services for Constellation's research center. This role owns the strategic direction, planning, budgets, and performance for IT, Security & Safety, Site Operations, and Catering. These functions share a common purpose: enabling world‑class AI safety research through excellence in our physical and digital environment.

As Director of Site Services, you'll define priorities and allocate resources across your portfolio. (Alternative titles for this role: Director of Workplace Services, Director of Infrastructure Operations.) You'll have high autonomy to shape how these teams work together, with direct accountability for strategic alignment with broader organizational goals.

This is a leadership role that requires both strategic altitude and hands‑on engagement. You’ll coach domain leads, shape organizational systems, and remain close enough to operational reality to make high‑judgment decisions that scale with the mission. Your work directly influences Constellation’s ability to scale programs, host exceptional people, and create an environment where complex work can flourish.

You will integrate four mission‑critical operational domains into one coherent system. The systems, standards, and culture you establish now will define how Constellation grows over the next several years.

You’ll lead a team of ~11 (growing to ~15+ over the next 1‑2 years), with four direct reports. Given our size and growth trajectory, this is a true player‑coach role: you’ll set direction and standards while also engaging directly where doing so strengthens judgment, accelerates execution, or ensures quality.
