Senior Mechanical Engineer

Raleigh–Durham, hybrid · Full-time, permanent · Market-leading compensation

Our client is a growing MEP engineering firm that designs hyperscale and colocation data centers across the East Coast. Their pipeline is booked well into 2028, and they're adding a senior mechanical engineer to lead cooling design from concept through commissioning.

What you'll do

• Lead mechanical design for data-center campuses: chilled-water plants, CRAH/fan-wall systems, and liquid cooling (direct-to-chip and rear-door) for high-density AI halls.
• Run load calculations, equipment selection and energy modeling to hit PUE and redundancy targets (N+1, 2N).
• Produce and check drawings and specs in Revit, and coordinate with electrical, structural and the owner's team.
• Support construction administration: submittals, RFIs, site visits and commissioning (L1–L5).
• Mentor junior engineers and act as a day-to-day contact for the client's design managers.

What you'll bring

• 6+ years of HVAC or mechanical design, ideally in data centers, healthcare, labs or other mission-critical buildings.
• A BS in Mechanical Engineering. A PE license, or progress toward one, is strongly preferred.
• A working knowledge of ASHRAE standards (including TC 9.9 thermal guidelines) and the IMC.
• Experience with liquid cooling or high-density design is a big plus.

Why this role

• Work on some of the largest AI infrastructure builds in the country.
• A clear path to Associate or Project Lead, and PE exam support.
• Health, dental and vision cover, a 401(k) match, PTO, and paid professional development.
