Mechanical Engineer - CFD; Data Center HVAC Design

Overview

SSOE 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. This role combines traditional mechanical system design with advanced airflow and thermal modeling to ensure high‑performance, energy‑efficient, and resilient environments.

In this role the candidate works closely with an integrated staff of in‑house engineering and architecture teams to ensure that these critical projects meet and exceed industry standards from scope development to commissioning and start‑up. SSOE brings decades of experience in power‑intensive, high‑tech, and mission‑critical environments across North America, making it an excellent choice for a career move.

• 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.

• 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.
