About the role

Senior technical mechanical engineer leading commissioning oversight for data center infrastructure within Apple’s IS&T Data Center Commissioning team. Governs end-to-end commissioning lifecycle (Levels 1–5) for new data centers, expansions, and critical spaces, focusing on mechanical cooling, hydronics, airflow, fire protection, and building automation, with extensive third-party management and cross-functional leadership.

Responsibilities

  • Serve as the primary mechanical commissioning senior engineer across all new Apple data centers and critical infrastructure, governing the complete Level 1 through Level 5 commissioning lifecycle.
  • Develop, author, and standardize global mechanical commissioning playbooks, test scripts, functional performance procedures, and Integrated Systems Testing (IST) execution plans.
  • Evaluate, onboard, manage, and audit third-party Commissioning Agents (CxA), mechanical contractors, and Test and Balance (TAB) firms during onsite testing and verification.
  • Perform technical commissionability reviews on Basis of Design (BOD), MEP drawing packages, P&IDs, and sequences of operations (SOO) to guarantee testability and operational resilience.
  • Oversee and validate Factory Acceptance Testing (FAT) for major mechanical equipment, including chillers, cooling towers, custom AHUs, CRAH/CRAC units, and hydronic pump skids.
  • Lead the technical validation of advanced high-density liquid cooling topologies, including direct-to-chip loops, hydronic distribution, secondary fluid quality, and CDU performance.
  • Oversee the commissioning of critical fire protection and life safety systems, while managing strict adherence to Methods of Procedure (MOPs) and mechanical Lockout/Tagout (LOTO) safety protocols.
  • Drive mechanical root cause analysis during live load testing, partnering with Controls and Electrical engineers to validate cross-domain interlocks, emergency power-off (EPO), and complex failover schemes.
  • Guide the operational turnover process by ensuring accurate baseline trending, comprehensive O&M documentation, warranty readiness, and hands-on facility training.

Qualifications

  • Bachelor's degree in Mechanical Engineering, Architectural Engineering, Systems Engineering, or a related engineering discipline (or equivalent practical/job-related experience).
  • 5+ years of direct experience commissioning and or managing the commissioning of mechanical and HVAC systems in a Hyperscale data center environment.
  • Understanding of large-scale mechanical cooling systems (such as central chilled water plants, cooling towers, air-cooled/water-cooled chillers, CRAH/CRAC units, and pumping infrastructure).
  • Experience with the commissioning, testing, and or validation of data center fire protection, suppression, and early warning fire detection systems.
  • Experience developing, reviewing, approving, and or overseeing the execution of Level 4 (Functional Performance Testing) and Level 5 (Integrated Systems Testing) test scripts and procedures.
  • Experience with mechanical Sequence of Operations (SOO) validation under dynamic load conditions.
  • Willingness and ability to travel approximately 40%, with availability for international travel as needed to support vendor factory testing and global site commissioning activities.
