Critical Mechanical Systems Specialist

Lead mechanical systems readiness for new capacity and ongoing reliability. Provide commissioning oversight, drive new site onboarding and transition, and execute site inspections/audits to uncover performance, efficiency, and reliability risks across chilled-water plants, CRAH/CRAC, cooling towers, heat-rejection systems, and controls/BMS. Ensure mechanical designs meet operational standards and that documentation and training are complete for Day 1 operations.

Responsibilities

• Commissioning oversight: Validate mechanical system performance and control sequences; track and close defects/punch-list items discovered pre-commissioning and during commissioning.

• Develop and conduct commissioning for infrastructure projects that are executed at operational datacenters.

• Conduct operational procedure validation during post turnover pre customer load deployment phase.

• Support the development of a robust process to standardize mechanical turnover documentation, ensure storage in the designated repository, and verify operator training and readiness.

• Site inspections / audits: Conduct site physicals and infrastructure assessments focused on mechanical reliability, efficiency, and risk; maintain and drive closure of mitigation plans.

• Design-to-operations bridge: Document field changes, communicate operational impacts to the gaining team, and ensure readiness gaps are closed prior to hand-off.

• Cross-functional coordination: Work with Design & Construction, Commissioning, Site Operations, and Reliability Engineering to align standards and continuously improve readiness playbooks.

• Provides continual evaluation of processes and procedures, responsible for suggesting methods to improve operation and efficiency of DC design and equipment.

Qualifications

• 7+ years 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/standards for hydronics and ventilation, and commissioning methodologies.

• Hands-on experience with submittal reviews, sequence of operations, functional performance testing, and punch-list closeout.

• Strong documentation discipline and stakeholder communication; proven 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.

Education/Certifications

• Bachelor’s in Mechanical Engineering (or equivalent practical experience).

• Preferred PMP, AHRAE certifications, or PE.

Work Conditions

• Supports 24×7 operations; occasional oncall rotation and night/weekend work.
