Mechanical Engineer – CFD (Data Center HVAC Design)

SSOE Group is seeking a Mechanical Engineer with a strong focus on Computational Fluid Dynamics (CFD) to support the design and optimization of HVAC systems for mission-critical data centers. The role involves developing engineering designs, performing CFD simulations, and collaborating with multidisciplinary teams to ensure high-performance and energy-efficient environments.

Responsibilities:

• Develop detailed engineering designs, technical project plans, specifications, drawings, and 3D models aligned with client requirements and industry standards
• Perform CFD simulations using tools such as Cadence (e.g., Fidelity/Pointwise or similar) to analyze airflow, temperature distribution, pressure gradients, and cooling effectiveness within data center environments
• Design and optimize HVAC systems including CRAH/CRAC units, chillers, cooling towers, containment systems (hot/cold aisle), ductwork, and ventilation strategies
• Conduct mechanical calculations including cooling load analysis, airflow distribution, pressure drop, pump head, and energy efficiency to support design decisions
• Interpret CFD results to recommend design improvements for thermal management, redundancy, and energy optimization (PUE reduction)
• Apply standard engineering practices while adapting designs to meet complex data center performance requirements
• Collaborate with multidisciplinary teams (Electrical, Structural, Architectural, and Controls) to integrate mechanical systems into coordinated design packages
• Participate in and facilitate internal/external design reviews, ensuring deliverables meet QA/QC standards and project milestones
• Perform site visits and field verifications to validate design assumptions, troubleshoot issues, and support construction activities
• Manage RFIs, submittals, and technical inquiries from contractors and vendors, ensuring accurate documentation and version control
• Support commissioning efforts by validating system performance against CFD predictions and design intent

Requirements:

• Bachelor's degree in Mechanical Engineering (ABET-accredited) or related discipline
• 8+ years of experience in mechanical/HVAC design, preferably in data centers or mission-critical facilities
• Hands-on experience with CFD modeling tools, including Cadence software
• Proficiency in AutoCAD and Revit
• Strong understanding of HVAC systems including chillers, air distribution, cooling strategies, and controls
• Knowledge of ASHRAE guidelines (especially TC 9.9 for data centers) and applicable building codes
• Ability to translate complex simulation data into actionable engineering decisions
• Strong communication skills to convey technical concepts to diverse stakeholders
• Professional Engineer (PE) license preferred or PE tracked
• Experience with Navisworks, PIPE-FLO, or similar hydraulic modeling tools
• Familiarity with data center standards (Uptime Institute, TIA-942)
• Experience with energy modeling and sustainability strategies for high-density environments
• Exposure to liquid cooling technologies (direct-to-chip, immersion cooling) is a plus
