Electrical Engineer - Li-Ion Batteries

Experienced Electrical Engineer specializing in Li-Ion battery powered systems, PCB/PCBA design, and power electronics, guiding development from concept to production for battery management, charging, and embedded hardware interfaces.

Responsibilities

• Design and develop PCBAs, schematics, and electrical circuits for new electronic products and battery-powered platforms.
• Create and maintain detailed schematics, BOMs, stack-ups, and supporting design documentation.
• Lead or participate in PCB layout reviews with a focus on signal integrity, manufacturability, thermal performance, and EMI/EMC best practices.
• Design and debug low-voltage DC circuits, power distribution networks, analog/digital interfaces, and embedded support circuitry.
• Develop circuitry supporting battery management systems (BMS) and TI fuel gauge ICs, as well as cell monitoring and balancing.
• Implement protection and safety circuitry for reliable operation and safety compliance.
• Develop circuitry for charging and power conversion systems.
• Support prototype assembly, SMT builds, bring-up, validation, and troubleshooting activities.
• Conduct bench-level debugging using oscilloscopes, logic analyzers, DMMs, and other lab instrumentation.
• Collaborate with manufacturing and suppliers to resolve design, assembly, and production issues.
• Define and support production test requirements and design-for-manufacturing (DFM) improvements.
• Assist with root cause investigations and corrective actions for field or production failures.
• Participate in all phases of product development from concept through production release.
• Work with mechanical, manufacturing, test, quality, and regulatory teams to ensure successful product execution.
• Lead or participate in design reviews, technical reviews, and risk assessments.
• Support sustaining engineering for products currently in production.
• Contribute to design control and quality system documentation, including V&V, traceability, risk analysis, change control, and regulatory submissions and compliance.
• Assist in ensuring compliance with standards such as ISO 13485, UL/IEC electrical safety, and UN transportation requirements where applicable.
• Participate in engineering change processes and documentation reviews to support controlled product development practices.

Requirements
