• Address challenges related to electronics packaging, encompassing tasks such as electrical isolation, sealing, thermal regulation, interconnection & shock and vibration mitigation
• Leading RCAs and cross-functional interface design
• Mechanical design analysis including thermal, structural, design for assembly, and design for test
• Own the design from conception through all of its iterations to mass-production
• Create drawing packages and manufacturing instructions for parts and assemblies
• Design and develop electromechanical and electrical systems in support of test stand safety, improvements, and simplification

What You'll Bring

• A degree in Mechanical/Mechatronics Engineering or a related field; bachelor's with 4+ years, or master's with 3+ years of relevant experience developing medium to high volume products
• Proven experience with electrical and mechanical design and proficiency in CAD (SolidWorks, NX, etc.)
• Expertise in cost modeling, multi-physics simulations (e.g., thermal, CFD, structural), and optimizations, with the ability to navigate system-level trade-offs and integrate them into architecture studies
• Strong mechanical and electrical engineering fundamentals, GD&T, and first principles hand calculations.
• Direct experience with high-volume manufacturing, fabrication, and prototyping techniques; experience with tight-tolerance, component design for harsh environments, DFM/DFA.
• Solid understanding of power distribution, electrical circuits, protection devices
• Superb understanding of creepage and clearance analysis and standards (ie IEC, UL etc.)
• Ability to model resistive losses, run current density analysis to optimize busbar geometry and sizing to meet system performance and mass requirements

Preferred Qualifications

• Familiar with electrical standards (NEC); experience with battery and power conversion standards (UL9540, UL1741) a plus
• Leadership, the ability to mentor, and well-developed communication, collaboration, and engagement skills working with a variety of teams and stakeholders
