Senior Mechanical Engineer

Are you looking for a new career opportunity with an exciting company?! Then we've got the right team for you! In this role, you're responsible for the duties listed below.

Immediate opening for a Senior Mechanical Engineer - Design and Thermal in the Burnsville / Faribault, MN area who possesses:

• Bachelor's degree in Mechanical Engineering or an accepted equivalent
• 7+ years of relevant mechanical engineering experience
• Strong hands-on mechanical design experience including layouts, 3D models, production drawings, and equipment packaging
• Independent thermal and fluid modeling experience, including CFD
• Experience validating simulation results against physical prototype and test data
• Solid Works or comparable professional CAD experience
• Experience with power equipment, power electronics, automotive, aerospace, HVAC, or another related high-power product environment

We are seeking a Senior Mechanical Engineer to lead mechanical design and thermal analysis activities for complex power equipment and high-power-density products. This senior individual-contributor role will combine hands‑on mechanical design, equipment packaging, CAD, controlled engineering documentation, CFD and thermal/fluid modeling, prototype validation, and manufacturing handoff. The ideal candidate will be equally comfortable designing physical hardware and independently developing thermal models, then validating those models against real-world test data and translating the results into practical design decisions.

• Owning mechanical design of assigned products from initial requirements through completed release packages
• Translating product requirements into mechanical layouts, assemblies, 3D models, production drawings, and controlled engineering documentation
• 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
• Comparing measured temperatures, flow characteristics, and mechanical responses against…
