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.

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 preferred or PE tracked.
• Experience with Navisworks, PIPE-FLO, or similar hydraulic modeling tools.
• Familiarity with data center standards (Uptime Institute, TIA-942).
