Note: The job is a remote job and is open to candidates in USA. Ursus, Inc. is seeking a Lead Mechanical Engineer for their Design and Engineering team. The role involves defining the mechanical cooling strategy and overseeing the design for data centers, focusing on efficiency and innovative cooling solutions.

Responsibilities

• Lead design and strategy for data center mechanical systems, including air, liquid, and hybrid cooling
• Define and maintain mechanical design standards for high-density air, rear-door heat exchangers, cold-plate, and immersion cooling
• Drive innovation to improve PUE, WUE, and overall energy efficiency
• Own and update basis-of-design, master specifications, drawings, and sequence-of-operations
• Oversee project-specific adaptations with external consultants and ensure quality through design reviews, inspections, and commissioning
• Perform CFD modeling, airflow/capacity planning, and specify critical equipment (chillers, pumps, CRAH/CRAC, dry coolers)
• Advance sustainability initiatives: free cooling, water-side economizers, and waste-heat reuse
• Collaborate with Electrical, Controls, and Construction teams at all design stages

Skills

• B.S. in Mechanical Engineering or equivalent technical discipline
• 7+ years of experience designing mechanical/cooling systems for data centers, with significant exposure to hyperscale or high-performance computing facilities
• Deep technical knowledge of chilled water systems, air-cooled and water-cooled chillers, direct liquid cooling, and heat rejection plant design
• Experience leading or managing a mechanical engineering team and directing external MEP consultants through a full design lifecycle
• Working command of ASHRAE TC 9.9 thermal guidelines, liquid cooling best practices, and relevant mechanical codes (IMC, ASME, NFPA)
• Demonstrated ability to develop and enforce design standards, basis of design documents, and master specifications across a multi-site portfolio
• Willingness to travel to project sites across the US (estimated 20-30%)
• Professional Engineer (PE) license or Chartered Engineer credential
• Direct experience with modular or prefabricated mechanical system design and off-site manufacturing coordination
• Hands-on CFD experience (6SigmaET, Ansys Icepak, Flotherm) and proficiency with Revit/BIM workflows
• Experience with medium-voltage (4.16 kV+) chiller applications and 800VDC power distribution architectures in data centers
• Background in owner/developer-side roles with direct accountability for system performance and reliability
• Familiarity with FM Global requirements for mechanical systems in mission-critical facilities

Benefits

• Medical, Dental, Vision, Commuter and 401K benefits with company matching
