What We Value: We are a diverse team of free thinkers, and fast movers united to help investors and creators energize the global economy. We are looking for individuals who thrive in a culture of builders and overachievers and embrace high performance, transparent feedback, and a mission-first approach. Our culture shapes our way of working and gets us where we want to be. • Seek Excellence. • Be Selective To Be Effective. • Be Highly Aligned, Loosely Coupled. • Disagree Transparently. • Encourage Independent Decision-Making. • Build Dream Teams. Who You Are: You are a commissioning leader who has taken large-scale, mission-critical data center facilities from equipment acceptance through energization, functional performance testing, and integrated systems testing, and who has done it across multiple facilities at once. You understand the electrical, mechanical, and controls systems well enough to challenge a test script, read a trend log, and know when a result does not prove design intent. You understand the commissioning process well enough to adapt it, not just follow it, and you can rebuild the test sequence when conditions change. That includes authoring the MOPs and risk controls for completing IST and load-based validation after early turnover, in live or partially occupied environments, without lowering the performance requirements the original plan was designed to prove. You lead teams from the front, hold contractors, OEMs, and third parties to a high standard, and refuse to let schedule pressure compromise a readiness gate. You are equally comfortable on the data hall floor with a startup technician and in the conference room briefing senior leadership on readiness, risk, and forecast. You believe the digital economy depends on infrastructure that is proven before it is energized for customers, and you take ownership of making that proof rigorous. What You'll Do: As Senior Manager, Commissioning at Galaxy's Helios campus in Afton, TX, you will lead all commissioning efforts across the campus on behalf of Galaxy as owner and developer. You will report to the VP, Campus Construction Manager and manage a team of three Commissioning Managers, each assigned to a data center facility. You will work closely with the general contractor's on-site team and Galaxy's third-party commissioning agent, and you will partner with Construction, Pre-Construction, Design Engineering, and Operations to ensure every facility is installed, tested, and proven to design intent, and handed to operations ready for customer service. You will set the commissioning standard for the campus and hold every facility to it. Key Responsibilities: • Own Campus Commissioning: Serve as Galaxy's single point of accountability for commissioning across the Helios campus, from design intent review through Level 1-5 commissioning, integrated systems testing (IST), and turnover to operations. Set the campus-wide standards and quality bar. • Lead the Commissioning Team: Manage three Commissioning Managers, each embedded at a data center facility. Standardize methods and reporting, balance resources across facilities, and develop talent. • Define and Enforce the Commissioning Plan: Own the campus commissioning plan and its alignment to the Owner's Project Requirements and Basis of Design, including acceptance criteria, test standards, and readiness gates. Ensure these are written into GC, trade, and OEM scopes. • Validate Testing and Design Intent: Review and approve test scripts, sequences of operation, and IST scenarios across critical power, mechanical cooling, and BAS/EPMS controls and telemetry. Ensure testing proves design intent, redundancy, and failure-mode response. • Drive Execution with the General Contractor: Integrate commissioning into the Primavera P6 master schedule and work daily with the GC's commissioning lead and trade partners to confirm readiness, resourcing, and OEM startup support. Hold the GC accountable through readiness reviews, deficiency tracking, and commercial remedies. • Direct the Third-Party Commissioning Agent and Issue Closeout: Manage the scope and performance of Galaxy's third-party agent, challenge findings, and maintain a campus-level issues log. Drive every item through root cause, corrective action, and retest to closure. • Coordinate Energization and OFCI Equipment: Plan utility energization and load bank testing, enforcing safe work during energized testing in partnership with EHS. Align OFCI equipment delivery, factory testing, and manufacturer startup with the commissioning sequence. Adapt the commissioning sequence and author MOPs to complete Level 4-5 and IST activities after early data hall turnover, without lowering acceptance criteria. • Deliver Operational Readiness and Customer Acceptance: Partner with Galaxy Operations and customer delivery teams on documentation, training, operating procedures, witnessed testing, and formal turnover, ensuring each facility meets acceptance criteria at handoff. • Report Readiness and Standardize: Provide candid readiness reporting to the VP and senior leadership, and feed lessons learned into design standards, specifications, and Pre-Construction planning. • Validate Controls, BAS/EPMS, and Telemetry: Ensure the BAS, EPMS, and associated controls are commissioned as a system, not just as individual points lists. Verify point-to-point integrity, alarm and trend configuration, and operator visibility across all critical power and mechanical systems, including through failure scenarios such as loss of utility, loss of a controls network or server, communication failure, and transfer events. Confirm that telemetry remains accurate and actionable so Operations can see, diagnose, and respond to any failure while redundancy is maintained. What We're Looking For: • Bachelor's degree in Electrical or Mechanical Engineering, or a related discipline, or equivalent experience. • 10+ years of experience commissioning mission-critical facilities, including 5+ years on large-scale data centers, with at least 3 years in a leadership role directing commissioning through Level 5 / IST. • Demonstrated success leading commissioning across multiple concurrent facilities on a single campus. • Experience managing and developing commissioning managers or engineers. • Deep technical knowledge of critical power systems, including medium- and low-voltage distribution, protective relaying, UPS, batteries, generators, and transfer systems. • Deep technical knowledge of mechanical cooling systems, including chilled water plants, heat rejection, air handling, pumps, and associated controls. • Working knowledge of BMS, EPMS, and SCADA architectures, sequences of operation, and fire and life safety system integration. • Experience developing, executing, and witnessing IST, including failure-mode and fault scenarios. • Familiarity with ASHRAE Guideline 0, NETA acceptance testing standards, NFPA 70E, and NFPA 110. • Experience directing GC commissioning teams and third-party commissioning agents, with strong command of test documentation, issue tracking, and P6 schedule integration. • Familiarity with Procore, Primavera P6, Bluebeam, SharePoint, and commissioning management platforms. • Full-time, on-site presence at Helios (Afton, TX) • Preferred: Professional Engineer (PE) license or commissioning certification (e.g., CxA, CCP, BCxP), prior owner-side or owner's representative experience, and OSHA 30. What You Bring: • A track record of leading and developing high-performing technical teams. • The conviction to hold readiness gates under schedule pressure, backed by data and clear communication. • Excellent communication skills and the ability to influence technical and executive stakeholders. • Sound judgment under pressure and a bias toward early, honest escalation. • A commitment to safety, rigor, and executional excellence. • A passion for building world-class infrastructure that supports the growth of the digital economy. What We Offer: • Competitive base salary and discretionary bonus • Paid Time Off • Company-paid health and protective benefits for employees, partners, and other dependents • Company Paid Holidays (14) • 3% 401(k) company contribution • Generous paid Parental Leave • Free virtual coaching and counseling sessions through Headspace • Opportunities to learn about the Crypto industry • Free daily snacks and daily meals • Smart, entrepreneurial, and fun colleagues • Employee Resource Groups *Benefits may vary depending on location.
