• You have a bachelor’s degree in electrical engineering.
• You have a minimum of 5 years of experience designing lithium battery management systems (BMS).
• You have general analog design experience and have created schematics and PCBs containing analog and mixed-signal circuits.
• You have experience designing cell sensing, protection, balancing, and isolation circuits for lithium battery packs.
• You are proficient with Microsoft Office.
• You have strong attention to detail.
• You are organized, focused and results oriented.
• You are a problem-solver with critical thinking and prioritizing skills.
• You have excellent verbal, written and interpersonal communication skills.

WE WOULD REALLY LIKE IT IF… (but it’s not a deal breaker)

• You have experience designing to environmental and EMI requirements such as RTCA DO-160 or MIL-STD-810/461, or with rechargeable lithium battery standards such as RTCA DO-311.
• You have experience with LiFePO4 (lithium iron phosphate) chemistry and/or Design for Manufacture and Design for Test (DFM & DFT).
• Design analog and mixed-signal schematics for BMS hardware, including cell voltage/current/temperature sensing, balancing, protection, and isolation, while coordinating with dedicated resources for PCB layout
• Support embedded software for BMS microcontrollers, including protection logic and monitoring functions
• Prototype, bring up, and validate BMS hardware at cell, module, and pack level
• Coordinate with other functional teams, including layout, mechanical, software, and certification engineers
• Build and troubleshoot hardware, including soldering, operation of test equipment, and daily work in both office and test lab environments
• Design hardware, embedded or PC-software tools to support product verification and manufacturing
• Prototype and execute test programs to verify compliance with applicable performance, regulatory, and quality requirements
• Create and document designs in required formats, including BOMs, ECOs, and work instructions
• We provide above-market pay and a comprehensive benefits package.
• We promote an environment where you can excel in your career while still maintaining a healthy work-life balance.
• Our facility is climate controlled, clean, organized, and safe. We operate in a professional, light manufacturing environment.
• We believe anything worth doing is worth doing right – every time.
• We have frequent events to keep work interesting. Our food drive is super impressive, we enjoy an annual food truck fest appreciation day, monthly fruit/donut day, employee luncheons throughout the year, wellness challenges with incentives, and frequent ticket raffles for local sporting and cultural events.
• We have a small company feel – even though we’re doing big things!
