About The Position

Seeking an experienced Mechanical Engineer to serve as a subject matter expert and technical authority for mechanical systems in mission-critical projects, including data centers and other high-availability facilities. The role focuses on 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. This is a remote position with anticipated travel of 10%–25% for project-site visits during construction administration and surveys of existing facilities. Approved business travel expenses are reimbursed under company policy. Candidates interested in office-based or hybrid work arrangements may discuss available options. The engineer leads mechanical design from feasibility through construction administration; develops cooling-system concepts; performs or oversees load analyses, equipment selection, and redundancy evaluations; and coordinates across project disciplines. The role also provides technical oversight of vendor equipment, supports utility capacity assessments and campus master planning, leads technical reviews and QA/QC, supports commissioning, and mentors junior engineers.

Requirements

  • 5–10 years of mechanical design experience in mission-critical environments.
  • Experience with hyperscale, colocation, enterprise, and edge data center environments.
  • Bachelor's degree in Mechanical Engineering.
  • Strong understanding of ASHRAE, NFPA, IMC, and local building-code requirements.
  • Excellent communication, technical leadership, and client-facing skills.

Nice To Haves

  • Professional Engineer (PE) license, or actively pursuing licensure.
  • LEED Accredited Professional and/or Certified Energy Manager (CEM) credential.
  • Experience with hyperscale, colocation, enterprise, healthcare, or other high-availability facilities.
  • Familiarity with direct-to-chip and immersion liquid-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.

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.
  • Travel for project-site visits during construction administration and site surveys for existing facilities.
