Ehvert Mission Critical, a business unit within Salas O’Brien has an immediate opening for a Senior Mechanical Engineer to join our team.
We are seeking an accomplished Senior Mechanical Engineer to join our mission-critical data center engineering team. In this role, you will provide technical and client leadership on the design, modeling, and coordination of complex mechanical systems for hyperscale and AI-driven data centers across the United States. Your expertise will span HVAC, piping, plumbing, cooling towers, chilled water systems, boilers, and other high-performance infrastructure supporting the world’s leading technology clients.
As a senior leader on our team, you will oversee all phases of mechanical engineering design and execution—from advanced calculations and technical documentation, to BIM coordination, project delivery, and direct client engagement. You will guide and mentor junior engineers, represent the firm in client meetings, and drive collaboration with architects, consultants, and contractors to ensure exceptional project outcomes.
This role requires multiple active Professional Engineer (PE) licenses across U.S. states, strong client-facing skills, and the flexibility to travel frequently to project sites nationwide. Candidates with proven leadership experience in mission-critical or large-scale industrial projects will excel in this role.
If you are a seasoned engineer who thrives in high-profile, fast-paced environments and enjoys leading teams to deliver world-class, energy-efficient facilities, this is a unique opportunity to shape the future of hyperscale and AI data center design.

• Lead mechanical engineering design activities and serve as the primary point of contact for major U.S. data center projects.
• Direct and oversee the design, modeling, and simulation of mechanical systems for hyperscale and AI-driven facilities, including HVAC, piping, plumbing, cooling towers, chilled water systems, and boilers.
• Supervise and mentor project engineers, providing technical guidance and ensuring quality across all project deliverables.
• Engage directly with clients, presenting design solutions, addressing technical challenges, and maintaining strong relationships.
• Prepare and review advanced engineering calculations, specifications, and detailed mechanical drawings.
• Champion the design of highly energy-efficient and sustainable systems aligned with client and industry standards.
• Lead BIM coordination with architects and engineers, resolving complex technical conflicts.
• Oversee construction administration, including the review of shop drawings, site visits, and compliance with safety standards and engineering codes.
• Ensure project requirements are consistently met in terms of scope, cost, and schedule.
• Utilize BIM and VDC tools for virtual construction and interdisciplinary coordination.
• Conduct site visits to monitor construction progress, ensuring quality and adherence to design intent.
• Promote the adoption of innovative technologies such as laser scanning for documentation and digital twins for facility operations.
