Mechanical Design Engineer

The role

As a Mechanical Design Engineer, you'll provide technical expertise for data center mechanical infrastructure, including cooling systems, HVAC, and critical equipment. You'll assess designs, capacity, reliability, and operational readiness to ensure data centers meet performance and scalability requirements. This is a build-phase role for someone who can independently evaluate complex systems while helping establish engineering standards and best practices for future deployments.

Travel: This position will require on-site presence at data centers.

Your responsibilities will include:

• Lead mechanical engineering evaluations for data center opportunities.
• Assess cooling infrastructure, HVAC systems, and critical mechanical equipment.
• Evaluate air-cooled, liquid-cooled, and hybrid cooling solutions for AI and hyperscale environments.
• Provide mechanical feasibility recommendations and Go/No-Go project input.
• Conduct technical due diligence on existing and new data center facilities.
• Review cooling capacity, chiller plants, CRAH/CRAC systems, and liquid cooling readiness.
• Evaluate equipment availability, vendor capabilities, lead times, and deployment risks.
• Support cooling topology, mechanical design strategy, and equipment selection decisions.
• Validate mechanical design assumptions, capacity requirements, and construction readiness
• Partner with engineering teams, vendors, and consultants to ensure scalable, reliable data center solutions.

We expect you to have:

• Experience supporting hyperscale data center or AI infrastructure development.
• Experience with BMS controls integration and mechanical systems commissioning.
• Professional Engineer (PE) license or similar professional certification.
• Experience evaluating colocation or build-to-suit mechanical infrastructure in a due diligence capacity.
• You're comfortable operating in ambiguity and building technical evaluation processes where none exist. You know how to independently assess complex mechanical infrastructure while helping define how future projects should be evaluated.
• 8+ years of experience in data center mechanical engineering, MEP design, or mission-critical mechanical systems.
• Experience with cooling topology design, liquid cooling systems, chiller plants, and CRAH/CRAC systems for high-density AI/hyperscale environments.
• Strong understanding of mechanical capacity planning, equipment selection, and capex trade-offs in data center design.
• Experience evaluating mechanical feasibility of sites or facilities prior to commercial commitment.
• Excellent communication and executive presentation skills.
• Bachelor's degree in Mechanical Engineering or a related discipline, or equivalent experience.

It will be an added bonus if you have:

• Experience supporting hyperscale data center or AI infrastructure development.
• Experience with BMS controls integration and mechanical systems commissioning.
• Professional Engineer (PE) license or similar professional certification.
• Experience evaluating colocation or build-to-suit mechanical infrastructure in a due diligence capacity.

Key employee benefits:

• Health insurance: 100% company-paid medical, dental, and vision coverage for employees and families.
• 401(k) plan: up to 4% company match with immediate vesting.
• Parental leave: 20 weeks paid for primary caregivers, 12 weeks for secondary caregivers.
• Remote work reimbursement: up to $85/month for mobile and internet.
• Disability & life insurance: company-paid short-term, long-term and life insurance coverage.
