Senior 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.

AI and Innovation

At SSOE, we don’t just talk about the future, we build it. As a leader in industry AI adoption, we empower our team to work smarter by providing responsible access to the industry leading AI Large Language Models, vibe-coding platforms, and securely integrating advanced tools into every role. From day one, you’ll receive the training and support needed to leverage AI as a core tool for enhancing productivity, sparking creativity, and streamlining complex workflows.

Responsibilities

The following duties are typical of the position but are not all encompassing. Responsibilities include those required to deliver quality service on schedule and within budget in a team environment.

• 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.

Qualifications

Required Qualifications:

 

• 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.

Preferred Qualifications:

 

• Professional Engineer (PE) license or tracked 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.
• Excellent verbal and written communication skills.
• Ability to work US hours of operation.

Additional Perks 

• Flexible and hybrid work options (role-dependent).     
• Learning and development support, including certification reimbursement (based on project requirements).   
• Employee engagement initiatives, clubs, and collaborative culture.
