Job summary

Ensurge Micropower in California seeks a Principal Engineer - Cell Design & Mechanical Architecture to lead mechanical design of solid-state microbattery cells. You will translate requirements into architecture, CAD models, mask layouts, and stacking concepts for manufacturability.

This hands-on leadership role requires strong design-for-manufacturing skills and collaboration with materials, process engineering, and packaging teams to optimize yield, performance, and reliability across cell

Qualifications

• Bachelor's or Master's degree in Mechanical Engineering, Materials Science, Manufacturing Engineering, Electrical Engineering, or related field.
• 8+ years of engineering experience with strong mechanical design background.
• Experience with 3D CAD and GD&T.
• Experience with mask-set design, photolithography layouts, microfabrication, MEMS, semiconductor devices, or similar technologies.
• Experience designing multilayer structures, precision assemblies, or stacked devices.

Responsibilities

• Lead the mechanical and structural design of solid-state microbattery cells and multilayer cell architectures.
• Develop multiple cell design concepts and evaluate trade-offs between energy density, performance, manufacturability, reliability, yield, and cost.
• Define cell dimensions, layer structures, interfaces, tolerances, alignment requirements, and mechanical constraints.
• Develop detailed 3D CAD models, drawings, assemblies, and engineering specifications.
• Apply GD&T and DFM principles to precision microbattery components and assemblies.
• Analyze mechanical stresses, dimensional variation, thermal expansion, layer interfaces, and other factors affecting cell reliability.
• Establish design rules and standards for future cell generations.
• Own mask-set design and layout development for microbattery fabrication.
• Translate cell architecture into mask layouts and manufacturing patterns.
• Collaborate with mask/fabrication partners and review mask designs for manufacturability.
• Drive design iterations based on process capability and yield.
