• Designing enclosures and mechanical assemblies for complex power equipment
• Developing designs using sheet metal, plastics, extrusions, and other appropriate materials and manufacturing processes
• Designing for safety, reliability, manufacturability, serviceability, and reuse across product platforms
• Coordinating PCB mounting and structural interfaces with Electrical and Power Conversion Engineering teams
• Developing equipment packaging that considers access, serviceability, structural requirements, and electrical integration
• Independently developing thermal and fluid models
• Using computational fluid dynamics where appropriate
• Defining model assumptions, boundary conditions, operating cases, acceptance limits, and uncertainty
• Evaluating airflow and liquid‑cooling performance
• Evaluating immersive and thermosiphon cooling concepts where applicable
• Analyzing component temperatures, heat dissipation, flow characteristics, and power density
• Translating thermal‑analysis results into practical mechanical design changes
• Designing and integrating cold plates
• Designing and integrating heat exchangers
• Supporting integration of pumps, fans, busbars, and thermal‑control loops
• Working with Electrical and Compliance teams to support effective power‑path and thermal‑management design
• Leading cross‑functional mechanical design reviews for assigned projects
• Evaluating Design for Manufacturability and assembly requirements
• Reviewing maintenance access and serviceability
• Supporting FMEA and AFMEA activities
• Evaluating IP‑rating, seismic, harsh‑environment, and other applicable product requirements
• Supporting NRTL construction reviews
• Preparing design packages and objective evidence supporting product and compliance requirements
• Planning and supporting prototype builds
• Designing applicable test fixtures
• Supporting thermal, flow, HALT, vibration, and shock testing

• Documenting causes and resolution of simulation or test discrepancies
• Refining product designs based on test and analysis results
• Preparing complete manufacturing work packages
• Creating and maintaining Bills of Materials
• Preparing drawings, build guidance, and controlled technical documentation
• Maintaining information within applicable product‑data‑management and release systems
• Partnering with Quality, Manufacturing, Sourcing, and suppliers to resolve production and field issues
• Evaluating new materials and manufacturing processes
• Supporting supplier changes, substitutions, and component obsolescence
• Introducing automation and rapid‑prototyping methods when beneficial
• Developing reusable platform designs rather than one‑off product solutions
• Creating repeatable and validated thermal‑analysis methods
