• Proficient in Altium Designer
• Experience with designing for testing and manufacturability
• Experience operating lab bench equipment (soldering, oscilloscopes, power supplies, electronic loads, measurement techniques…etc.)
• Experience in high-current and high-voltage design and layout practice: FET drive, thermal design, copper sizing, creepage and clearance
• Experience with lithium-ion battery systems: pack behavior, cell monitoring and balancing, and current, voltage, and temperature measurement chains
• Experience with ARM Cortex MCUs and FPGAs
• Experience designing power electronics
• Experience designing both digital and analog circuits
• Experience designing products through high volume production
• Experience designing electronics for harsh environments
• A systematic approach to debugging, isolating faults to root cause and documenting what you found
