Internship Duration: May 2026 - August 2026Â
Role Summary
Amperesand is working to develop, build, test, and validate a ground-up redesigned next-generation solid state transformer (SST) and the power stage modules (PSMs) that convert power from medium-voltage AC to customer-facing DC output.  This internship will include building and testing of prototype units, root cause analysis of issues found, and design and changes of parts to fix or improve.  Â
Responsibilities:Â
- UtilizeCAD software to create detailed mechanical designs.  3DX/Catia experience preferred but not required.Â
- Model and design complex electro-mechanical parts, including plastics, sheet metal, insulators, magnetic components, and high-voltage connectors.
- Perform mechanical design analysisby means offirst principal calculation or simulation with commercial software, including structural FEA, thermal CFD, vibration, and fatigue assessments.Â
- Solve packaging challenges involving electrical isolation, sealing, thermal dissipation, EMI/EMC shielding, and mechanical shock/vibration.
- Â Perform prototype development, fabrication, assembly, and mechanical testing of new designs.
- Â Support root-cause analysis of design issues in pilot or production builds and lead iterative improvements.Â
- Â Define and execute validation test plans including structural, thermal, and environmental testing.Â
- 2D drawings with GD&T for production and inspection.
- Create engineering documentation, tolerance stacks, BOMs, and release packages through PLM systems.
- Â Collaborate cross-functionally with electrical, thermal, firmware and controls, manufacturing, test, and industrial design teams.
- Â Work closely with suppliers to optimize DFM, DFA, and tooling strategies for high-volume production.Â
Qualifications:Â
- Final year undergraduate standing or graduate study inMechanical Engineering or a closely-related field.Â
- Expertise in CAD modeling using 3D EXPERIENCE (CATIA V6/V5), SolidWorks, NX, or Creo.Â
- Â Deep understanding of mechanical fundamentals-statics, dynamics, heat transfer, and materials.
- Working knowledge of materials: metals (aluminum, steel), plastics, ceramics, gaskets, potting compounds.
- Comfortable with root-cause analysis, failure mode resolution, and mechanical reliability testing.
- Passion for product innovation, sustainability, and enabling electrification through engineering excellence.
Bonus Qualifications:Â
- Strong background in structural, thermal, and vibration analysis using commercial software,e.g.AnsysÂ
- Proficiency in GD&T, tolerance analysis, and DFM/DFA principles.Â
- Familiarity with PCBAs, connectors, and mechanical integration of high-density electronic assemblies.
- Experience with high-volume manufacturing processes such as injection molding, die casting, extrusion, and sheet metal forming.
- Experience with medium- to high-voltage systems and insulation coordination (creepage, clearance, potting, sealing).
- Experience working in Agile development environments, including task management and sprint planning using Scrum methodologies and tools like Jira.
Please note: This role requires working on-site 5 days a week. We do not offer hybrid or remote options.Â
Compensation: $30 - $45/hour depending on location and level of experienceÂ
