Senior Mechanical Engineer

About the role

The New York–based team at Arup is seeking a Senior Mechanical Engineer to support mission-critical data center projects across the New York metro area and the broader Northeast region.

Responsibilities

• Lead mechanical engineering design for mission-critical data center projects, including chilled-water and DX cooling systems, airside distribution, CRAH/CRAC configurations, thermal management strategies, and high-efficiency hydronic plant systems.
• Deliver resilient designs tailored to dense urban environments, addressing space constraints, noise and vibration, redundancy requirements, constructability, and phased build-outs.
• Collaborate with electrical, ICT, structural, fire/life safety, and commissioning teams—as well as project managers—to deliver fully integrated, scalable, and highly available data center solutions.
• Absorb, supervise, and mentor junior engineers; provide timely feedback, recognition, and technical guidance to support a high-performance engineering culture.
• Support successful delivery, repeat work, and long-term partnerships with hyperscale, colocation, and enterprise data center clients.
• Prepare drawings, specifications, technical reports, basis-of-design documents, and presentation materials that align with NYC and Northeast codes, utility requirements, and industry standards (ASHRAE TC 9.9, Uptime Institute, etc.).
• Present technical material to both technical and non-technical audiences through design workshops, client reviews, regulatory discussions, and internal knowledge-sharing forums.
• Participate in local and national mission-critical and data center organizations to stay current with evolving technologies, codes, and market trends.
• Owning quality standards, risk identification, commercial performance, and client engagement for assigned projects.

Requirements

• Bachelor’s degree in Mechanical or Architectural Engineering required.
• Minimum 6 years of professional experience designing HVAC systems, with 2–3+ years focused on data center or mission-critical facilities, including cooling plant design, redundancy planning, thermal modeling, and airside/hydronic systems.
• Experience working within New York City and Northeast regulatory environments strongly preferred.
• Proficiency in Revit MEP; experience with CFD modeling, load calculations, and mechanical system analysis is a plus.
• Strong interpersonal and communication skills, with the ability to collaborate effectively across disciplines in fast-paced project environments.
• Credentialed Professional Engineer (PE) license preferred; data-center-specific certifications or coursework (Uptime, ASHRAE, DCEP, etc.) are a plus.
