Electrical Design Engineer (Li-ion Battery Management Systems)

The Position

As an Electrical Design Engineer, you will design battery management systems (BMS) for lithium-ion aviation batteries, with an emphasis on digital control, and analog and mixed-signal hardware. Experience the entire product lifecycle, from concept and requirements, through design, implementation, testing and certification, and field application. You can expect a variety of opportunities ranging from precision cell voltage, current, and temperature sensing, protection and isolation circuits, cell balancing, lithium battery management, and integration with aircraft power systems.

THIS POSITION MAY BE FOR YOU IF

• 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.
• (but it's not a deal breaker) You have experience with LiFePO4 (lithium iron phosphate) chemistry and/or Design for Manufacture and Design for Test (DFM & DFT).

WHAT YOU CAN EXPECT FROM ONE DAY TO THE NEXT

• 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.
• Cookordination 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.
• Create and document designs in required formats, including BOMs, ECOs, and work instructions.
• Prototype and execute test programs to verify compliance with applicable performance, regulatory, and quality requirements.
