About The Position

The Critical Mechanical Systems Specialist leads mechanical systems readiness for new capacity and ongoing reliability across data center sites. The role provides commissioning oversight, drives new-site onboarding and transition, and conducts site inspections and audits to identify performance, efficiency, and reliability risks involving chilled-water plants, CRAH/CRAC systems, cooling towers, heat-rejection systems, and controls/BMS. The specialist ensures mechanical designs meet operational standards and that documentation and training are complete for Day 1 operations.

The position develops and conducts commissioning for infrastructure projects at operational data centers, validates operational procedures after turnover and before customer load deployment, and helps standardize mechanical turnover documentation, repository storage, operator training, and readiness. It bridges design and operations by documenting field changes, communicating operational impacts, and closing readiness gaps before hand-off. The specialist coordinates with Design & Construction, Commissioning, Site Operations, and Reliability Engineering to align standards and improve readiness playbooks, while continually evaluating processes and recommending improvements to data center design and equipment operation and efficiency.

The role supports 24×7 operations, with occasional on-call rotation and night or weekend work. It involves working in mechanical and electrical rooms around energized systems while following LOTO and NFPA 70E, and travel to supported sites of approximately 50%.

Requirements

• At least 7 years of experience in mission-critical facilities, with depth in chilled-water plants, CRAH/CRAC, heat rejection, and control systems/BMS.
• Working fluency with ASHRAE TC9.9 guidance, codes and standards for hydronics and ventilation, and commissioning methodologies.
• Hands-on experience with submittal reviews, sequences of operations, functional performance testing, and punch-list closeout.
• Strong documentation discipline and stakeholder communication skills, with demonstrated ability to drive multi-site mechanical programs.
• Strong analytical skills.
• Experience and knowledge of testing and commissioning methodologies.
• Experience with CMMS, DCIM/BMS integrations, and incident/RCA processes.
• Bachelor’s degree in Mechanical Engineering or equivalent practical experience.
• Ability to support 24×7 operations, including occasional on-call rotation and night or weekend work.
• Ability to work in mechanical and electrical rooms around energized systems while following LOTO and NFPA 70E.
• Ability to travel to supported sites approximately 50%.

Nice To Haves

• PMP certification.
• AHRAE certifications.
• Professional Engineer (PE) license.

Responsibilities

• Validate mechanical system performance and control sequences, and track and close defects and punch-list items found before and during commissioning.
• Develop and conduct commissioning for infrastructure projects executed at operational data centers.
• Validate operational procedures during the post-turnover, pre-customer-load-deployment phase.
• Help develop a standardized process for mechanical turnover documentation, ensure documentation is stored in the designated repository, and verify operator training and readiness.
• Conduct site physicals and infrastructure assessments focused on mechanical reliability, efficiency, and risk, and maintain and drive closure of mitigation plans.
• Document field changes, communicate operational impacts to the gaining team, and ensure readiness gaps are closed before hand-off.
• Coordinate with Design & Construction, Commissioning, Site Operations, and Reliability Engineering to align standards and continuously improve readiness playbooks.
• Continually evaluate processes and procedures and suggest methods to improve data center design and equipment operation and efficiency.
