We are seeking a highly skilled Electrical Design Engineer to join our team, specializing in the design and development of circuit boards for battery packs and power solutions. The ideal candidate will be responsible for designing schematics, creating PCB layouts, and writing microcontroller firmware. This role is critical to developing innovative battery management solutions that meet performance, reliability, and safety requirements.

Job Duties :

Design schematics and PCBs for battery packs and battery management systems (BMS).

Select and integrate power management ICs, MOSFETs, microcontrollers (Microchip PIC, ARM, etc.), and communication interfaces (I2C, SPI, CAN, UART).

Design analog and digital circuits, including current sensing, voltage regulation, and protection circuits.

Develop high-density, multi-layer PCB layouts.

Collaborate with fabrication and assembly vendors to ensure DFM (Design for Manufacturability) and DFA (Design for Assembly) best practices.

Develop and debug firmware for Microchip PIC microcontrollers (or similar MCUs).

Implement battery charging algorithms, fault detection, and communication protocols.

Work with low-power embedded systems to ensure efficient power consumption.

Develop and execute test plans to validate circuit board designs.

Debug hardware and firmware issues using oscilloscopes, logic analyzers, and other lab tools.

Ensure compliance with safety and regulatory standards (UL, IEC, ISO).

Collaborate with mechanical engineers to integrate electronics into battery enclosures.

Work with manufacturing teams to improve assembly processes and yield.

Support failure analysis and troubleshooting of field issues.

Qualifications :

Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field (or equivalent work experience).

5+ years of experience designing printed circuit board assemblies (PCBA).

Strong experience with schematic capture and PCB layout tools.

Proficiency in microcontrollers and embedded C programming.

Experience with battery management systems (BMS), power electronics, and safety circuits.

Knowledge of electronics testing, debugging tools, and regulatory compliance.

Experience with high-power battery packs (e.g., lithium-ion, NMC, LFP).

Knowledge of communication protocols (I2C, SPI, CAN, RS-485).

Familiarity with wireless charging and energy storage systems.

Qualified applicants will receive consideration for employment without regard to race, color, age, religion, sex, sexual orientation, gender identity, national origin, disability, protected veteran status, or genetic information.
