  • Creating commissioning plans, test procedures, and comprehensive final reports while documenting deficiencies using structured tracking systems and overseeing resolution through substantial completion
  • Directing cross-functional commissioning teams of 2-8+ engineers and technicians while coordinating with project stakeholders throughout the project lifecycle from design phase through transition to operations
  • Conducting commissioning training for Owner's operations staff and providing knowledge transfer documentation on larger projects
  • Managing commissioning schedules, ensuring optimal team utilization, identifying potential failure modes, and developing mitigation strategies
  • Interpreting project drawings and specifications, identifying design issues, and communicating technical concerns effectively to clients and project teams

Desired experience and technical skills:

Requirements:

  • Minimum 7 years of documented experience leading hands-on data center commissioning activities with at least 5 years specifically in data center cooling systems and building monitoring and automation commissioning
  • Proven track record leading mechanical and controls commissioning of facilities with power densities exceeding 25kW per rack
  • Deep understanding of cooling plant sequences of operations, redundancy concepts, and their implementation in mission critical designs
  • Experience working in partnership with major cooling equipment manufacturers (JCI, Daikin, Trane, Vertiv, Schneider, etc.)
  • Proficiency in commissioning management software platforms (CxAlloy, ACC, Procore, Bluebeam, and similar)
  • Advanced knowledge of commissioning processes for data center cooling infrastructure and building monitoring and controls platforms
  • Expertise in precision HVAC systems, glycol cooling, and thermal management strategies including liquid cooling applications
  • Strong understanding of BAS/DCIM integration, monitoring protocols, and alarm management protocols
  • Ability to travel 50% annually throughout North America and work in active construction environments, climb ladders, and work in mechanical/electrical rooms with availability for occasional emergency commissioning support and weekend/evening critical testing activities

Preferred:

  • Bachelor's degree in related technical field
  • Professional Engineer (PE) license and PMP certifications
