About The Position

Seeking an experienced Mechanical Engineer to serve as the mechanical subject matter expert for mission-critical mechanical systems in data centers and other high-availability facilities. The role provides technical authority for HVAC, cooling infrastructure, heat-rejection systems, controls integration, and mechanical resiliency strategies, developing innovative, energy-efficient, and maintainable solutions that meet industry standards and client performance objectives.

The position is remote, with occasional travel for project-site visits during construction administration and surveys of existing facilities for brownfield projects. Anticipated travel is 10%–25%. Approved business travel expenses are reimbursed under company travel policies. Candidates who prefer office-based or hybrid arrangements may discuss available options. Salary range is $120,000–$170,000 annually.

The engineer leads mechanical design throughout project phases, from feasibility through construction administration, and supports technical reviews, quality assurance and quality control, commissioning, and staff development. The role coordinates with other design disciplines and provides technical oversight of mechanical equipment and systems.

• Familiarity with liquid-cooling technologies, including direct-to-chip and immersion cooling applications.
• Experience with central utility plants ranging from 3 MW to 100+ MW campuses.
• Knowledge of ASHRAE TC 9.9 thermal guidelines, energy-efficiency strategies, water usage effectiveness (WUE), and power usage effectiveness (PUE) considerations.
• Experience supporting commissioning, integrated systems testing (IST), and operational readiness reviews.
• Professional Engineer (PE) license, or actively pursuing licensure.
• LEED Accredited Professional and/or Certified Energy Manager (CEM).

Responsibilities

• Serve as the lead mechanical subject matter expert for mission-critical and data-center projects.
• Develop cooling-system concepts, including air-cooled and water-cooled chilled-water plants, direct-expansion systems, and liquid-cooling solutions.
• Lead mechanical design through feasibility, concept, schematic, design development, construction documents, and construction administration phases.
• Perform and oversee cooling-load analysis, equipment selection, and redundancy evaluations.
• Develop mechanical resiliency strategies for N, N+1, 2N, and concurrently maintainable designs.
• Coordinate with electrical, controls, plumbing, structural, telecommunications, and architectural disciplines.
• Provide technical oversight of vendor equipment, including chillers, cooling towers, CRAHs, AHUs, fan walls, CDU systems, pumps, and BAS controls.
• Support utility-capacity assessments and campus master-planning efforts.
• Lead technical reviews and QA/QC processes and support commissioning activities.
• Mentor junior mechanical engineers and support technical staff development.
