About The Position

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

This is a remote position with anticipated travel of 10%–25% for project site visits during construction administration and site surveys at existing facilities. Approved business travel expenses are reimbursed under company travel policies. Candidates interested in an office-based or hybrid arrangement may discuss available options. The stated annual salary range is $120,000–$170,000.

The engineer leads mechanical design from feasibility through construction administration, oversees cooling analyses and equipment selection, coordinates with other engineering and design disciplines, and provides technical leadership, quality reviews, commissioning support, and mentorship. Projects may include hyperscale, colocation, enterprise, healthcare, and other high-availability facilities.

Requirements

• 5–10 years of mechanical design experience in mission-critical environments.
• Bachelor’s degree in Mechanical Engineering.

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.
• 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.
• Support commissioning, integrated systems testing, and operational readiness reviews.
