ABOUT THIS ROLE 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. WHAT YOU'LL BE WORKING ON Multi-Campus Strategic Leadership - Provide high-level commissioning oversight and direction across multiple campuses, ensuring operational alignment, cohesive strategy, and exceptional client relations across the portfolio. - Drive consistency in commissioning execution across sites, identifying cross-project patterns, recurring issues, and systemic risks, and translating lessons learned into program-level change. - Represent Crusoe Commissioning (CCx) in cross-functional governance forums, leadership reviews, and client-facing engagements, translating technical complexity into clear business impact. Technical Authority & Decision-Making - Serve as the "Master of Discipline" for mechanical systems — responsible for high-impact, technically complex decisions that shape site outcomes, including system readiness, test acceptance, and risk-based deviations. - Act as the recognized escalation authority for complex technical issues across all project phases, rapidly resolving problems that span disciplines, vendors, and project boundaries. - Own technical sign-offs that cross project boundaries, and maintain exceptional customer communication that builds confidence in Crusoe's delivery. - Maintain comprehensive understanding of building systems — cooling and heat rejection, hydronics, BMS/controls, and electrical interfaces —including how mechanical plant performance impacts data center availability and thermal reliability. Programmatic Process Ownership - Own the development and continuous improvement of the commissioning program: create, pilot, deploy, and validate new and improved processes, standards, and governance documents (e.g., FWT program, deficiency management, script library governance). - Conduct QA audits and drive root cause analysis on systemic issues; establish the frameworks by which program quality is measured and improved. - Define what "good" looks like across the L0–L6 lifecycle and drive adoption of improvements across Crusoe portfolio. Quoting & Financial Oversight - Support CCx with all quoting activities, taking a lead role in financial accuracy, bid leveling, and the strategic pursuit of new business. - Manage program-level CxA and vendor commercial outcomes — scope development, change order review, and performance-based accountability. - Bring deep contractual and risk understanding to protect the business in vendor negotiations and commissioning scope decisions. Trade Partner & CxA Performance - Manage and analyze trade partner and third-party commissioning agent execution to ensure high standards, accountability, and continuous improvement in external collaborations. - Set the performance bar for CxAs across the program, driving accountability across vendors through structured performance management, deliverable tracking, and data-driven scorecards. - Build long-term, trust-based partnerships with key external partners (clients, vendors, OEMs) at senior level. Mentorship & Team Elevation - Actively coach and develop team members across the organization, bridging the gap between current performance and exceptional. - Mentor engineers across all levels, develop next-level talent, and elevate the team around you to your own performance standard. - Anchor calibration and growth conversations in specific, observable behaviors, building the technical bench that scales with Crusoe's growth.
