Internship Duration: May 2026 - August 2026
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.
Responsibilities:
- UtilizeCAD software to create detailed mechanical designs. 3DX/Catia experience preferred but not required.
- 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.
- Solve packaging challenges involving electrical isolation, sealing, thermal dissipation, EMI/EMC shielding, and mechanical shock/vibration.
- Perform prototype development, fabrication, assembly, and mechanical testing of new designs.
- Support root-cause analysis of design issues in pilot or production builds and lead iterative improvements.
- Define and execute validation test plans including structural, thermal, and environmental testing.
- 2D drawings with GD&T for production and inspection.
- Create engineering documentation, tolerance stacks, BOMs, and release packages through PLM systems.
- Collaborate cross-functionally with electrical, thermal, firmware and controls, manufacturing, test, and industrial design teams.
- Work closely with suppliers to optimize DFM, DFA, and tooling strategies for high-volume production.
Qualifications:
- Final year undergraduate standing or graduate study inMechanical Engineering or a closely-related field.
- Expertise in CAD modeling using 3D EXPERIENCE (CATIA V6/V5), SolidWorks, NX, or Creo.
- 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:
- Strong background in structural, thermal, and vibration analysis using commercial software,e.g.Ansys
- Proficiency in GD&T, tolerance analysis, and DFM/DFA principles.
- 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.
Compensation: $30 - $45/hour depending on location and level of experience
