Mechanical Engineer

Location: Seattle, WA or San Francisco Bay Area, CA

Our client, an organization developing advanced computing infrastructure, is seeking an experienced Mechanical Engineer to support the design and delivery of sophisticated data center environments. This position offers the opportunity to guide mechanical systems that support demanding technology applications, with a particular emphasis on cooling performance, reliability, and long-term scalability.

The ideal candidate brings extensive experience in mission-critical facilities, sound engineering judgment, and the ability to independently manage complex technical initiatives. This individual will work closely with multidisciplinary teams and external partners to develop practical solutions throughout the engineering and construction lifecycle.

This Role Offers

• Opportunity to contribute to sophisticated infrastructure projects supporting emerging computing technologies.
• Significant responsibility for technical decisions, system design, and project execution.
• Collaborative environment with direct involvement in engineering and operational planning.
• Exposure to advanced thermal management technologies and evolving facility requirements.
• Opportunity to help establish engineering practices and technical standards for future development.
• Equity participation as part of the organization's compensation philosophy.

Responsibilities

• Evaluate potential facility locations to determine mechanical infrastructure capabilities, cooling requirements, utility availability, and opportunities for future expansion.
• Develop engineering design criteria, technical specifications, and mechanical system standards to support reliable facility performance.
• Lead the planning and evaluation of thermal management solutions, including conventional cooling equipment and liquid-based technologies for high-density computing applications.
• Assess mechanical system capacity against operational demands, identifying performance limitations, technical risks, and opportunities for improvement.
• Coordinate with outside engineering firms, equipment providers, and construction partners to review technical documentation, engineering calculations, and project deliverables.
• Partner with electrical and infrastructure engineering teams to align mechanical system designs with overall facility performance and efficiency objectives.
• Provide technical oversight during construction, equipment installation, system testing, commissioning, and operational transition.
• Support equipment selection, supplier coordination, and project scheduling to address technical requirements and procurement considerations.
• Contribute to the development of repeatable engineering approaches that improve consistency, scalability, and execution across future projects.

Qualifications

• Bachelor's degree in Mechanical Engineering or a closely related technical discipline.
• At least seven years of professional mechanical engineering experience, including four or more years supporting data centers or comparable mission-critical environments.
• Demonstrated ability to independently evaluate facility infrastructure and establish engineering design requirements, specifications, and technical standards.
• Strong understanding of mechanical cooling systems, thermal management principles, and air-based, liquid-based, and hybrid cooling approaches.
• Practical experience with high-density cooling technologies, including liquid distribution equipment, direct-to-chip applications, and associated facility systems.
• Proven ability to coordinate external engineering consultants, contractors, and technical stakeholders throughout design and construction activities.
• Familiarity with applicable mechanical codes, ASHRAE thermal guidelines, and recognized data center reliability standards.
• Professional Engineer (PE) licensure and experience supporting high-performance computing environments are advantageous.
• Exposure to computational fluid dynamics, advanced cooling configurations, or alternative heat management approaches is beneficial.
