• Experience in analog and/or power electronics design.
• Experience in electronic circuit design and development involving mixed-signal systems or relevant experience.
• Excellent written and verbal communication skills, including experience presenting data to cross-functional teams and/or management.
• Detail-oriented, with a commitment to product excellence.

Nice To Haves

• Background in one or more of the following: power electronics, battery management (fuel gauge and charger), portable consumer electronics, medical electronics, or automotive electronics.
• Experience with high-volume manufacturing.
• Knowledge of one or more scripting languages or environments, such as Python, Shell, Unix, or MATLAB, for test automation and data analysis.
• Understanding of silicon manufacturing processes and how semiconductor devices and associated parasitic subcircuits are created.

Responsibilities

• Design BMUs from concept through mass production, focusing on detailed board-level design.
• Advance technology to maximize performance while minimizing volume.
• Collaborate with cross-functional partners, including Product Design, System EE, Cell Engineering, Firmware, and Algorithms, to ensure timely and on-budget product development.
• Investigate problems or issues and prepare reports.
• Develop schematics and bills of materials (BOMs) to satisfy design requirements.
• Develop PCB layout guidelines and guide Layout Engineers to meet physical and electrical requirements.
• Specify custom parts and PCBs for BMUs.
• Analyze designs using simulation tools and calculations to verify conformance with requirements.
• Conduct design validation on prototypes and implement the design.
• Conduct design reviews, incorporate team feedback, and release design documents for builds.
• Specify production test plans and limits and work with contract manufacturing partners to implement them.
