Senior Staff Commissioning Engineer, Mechanical

As a Senior Staff Commissioning Engineer, you will serve as a campus and multi-campus technical authority for commissioning across Crusoe's data center portfolio. You own outcomes across projects — setting technical direction for the mechanical discipline, governing the commissioning program itself, and serving as the trusted resource for the highest-impact, most technically complex decisions that shape site outcomes. You operate as a "Master of Discipline": the escalation point of last resort, the standard-setter for trade partner and CxA performance, and a force multiplier who elevates every engineer around you. This role blends deep technical mastery with programmatic ownership, commercial fluency, and executive-level communication that builds client and stakeholder confidence in Crusoe.
