Mechanical Engineer – CFD (Data Center HVAC Design)

SSOE, Inc. • Nashville, TN

2d • Hybrid

About The Position

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, you will work closely with an exceptional and fully 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 throughout North America, making us an excellent choice for your next career move.

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.

Nice To Haves

• 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.

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, submittts, 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.

Benefits

• Competitive Salary: $110k - $135k / year depending on location, education, experience, and certifications.
• Bonus and Incentives: Eligibility for our annual target bonus/incentive program based on company and individual performance and goals.
• Ownership Opportunities: As an employee-owned firm, we offer ownership opportunities to all employees at the associate level and above. This senior associate-level role will allow you to become a shareholder of SSOE.
• Comprehensive Benefits: Health, dental, and vision insurance, life insurance, 401K retirement savings plan (with company matching), professional development and training, generous PTO, and paid holidays.
• Continuous Learning: Embrace a culture of perpetual learning where curiosity is celebrated, innovative ideas are welcomed, and your career growth aspirations are fully supported.
• Career Stability: A diversity of market sectors, project types, and geographic locations that help insulate your career from economic ups and downs.
• Career Advancement: Embark on a structured career journey with abundant opportunities for growth and advancement.
• Holistic Compensation: A holistic approach to compensation and benefits that supports your physical and mental health, encourages work-life balance, and empowers your career advancement and financial success.
