Job Family: Mechanical Design Engineering
Job Profile Title: Principal Mechanical Design Engineer
Location/ Division Specific Information: Austin, TX; this position is remote eligible
How will you make an impact?
We are seeking a highly skilled, technically proficient and detail-oriented Principal Mechanical Engineer with expertise in metal structures, frame design, pipes and fabrication to support the development of power and cooling infrastructure for data centers. This role is critical in designing robust mechanical systems that house and support electrical and thermal management equipment, ensuring structural integrity, manufacturability, and compliance with industry standards.
What will you do?
Experience designing and integrating hydronic systems including pumps, piping networks, valves, and heat exchangers for data center cooling applications.
Knowledge of fluid dynamics, pressure drop calculations, and pipe sizing for chilled water and glycol-based systems.
Understanding of installation constraints, maintenance access, and serviceability in large-scale mechanical infrastructure.
Design and develop mechanical frames, enclosures, and support structures for data center power and cooling products (e.g., UPS systems, battery racks, CRAC units, containment systems, LVS, MVS).
Perform advanced structural analysis using FEA tools to validate mechanical integrity under static, dynamic, seismic, and thermal loads.
Analyze load paths, stress concentrations, and fatigue life of structural components to ensure long-term reliability.
Design metal enclosures with considerations for airflow, thermal containment, EMI shielding, and environmental protection.
Evaluate and implement new materials, coatings, and fabrication technologies to enhance product performance and reliability.
Participate in customer engagements and site visits to understand deployment constraints and gather feedback for design improvements.
Create detailed CAD models and fabrication drawings, including weldments, sheet metal, and machined parts
Select appropriate materials and fabrication methods to optimize cost, performance, and reliability
Collaborate with electrical, thermal, and systems engineering teams to integrate mechanical designs with functional components.
Lead mechanical design reviews and contribute to cross-functional design validation efforts.
Develop and maintain design documentation including BOMs, specifications, test plans, and engineering change orders (ECOs).
Drive continuous improvement in mechanical design for manufacturability (DFM), cost reduction, and performance optimization.
Interface with suppliers and customers to resolve fabrication issues and ensure quality standards are met.
Support lifecycle management of mechanical components, including obsolescence planning and alternate sourcing.
Conduct root cause analysis and corrective actions for mechanical failures or field issues.
Ensure mechanical designs support airflow management, thermal containment, and integration with cooling systems (e.g., in-row cooling, rear door heat exchangers).
Collaborate with compliance and certification teams to ensure mechanical designs meet global regulatory requirements (e.g., UL, CE, RoHS, REACH)
May perform other duties and responsibilities as assigned
