Power Electronic Engineer
Joplin, MissouriAre you a seasoned Power Electronics Engineer looking to lead cutting-edge innovations in high-power DC-DC conversion and high-current relay design? Join our dynamic team, where your expertise will drive the future of advanced battery electronics systems for mission-critical applications. If you're passionate about solving complex challenges in harsh environments and mentoring the next generation of engineers, this role offers the perfect opportunity to make a significant impact!
Power Electronics Engineer - Manufacturing
Senior Power Electronics Engineer leads the design and maintenance of electronic systems across various products, with a focus on power conversion and solid-state relays. This role is primarily responsible for designing DC power electronics, with occasional work on AC systems, to manage battery charging, regulate voltage during battery discharge, and implement safety disconnects to prevent charging or discharging under load. Additional responsibilities may include contributing to the design of other battery-related systems, such as telemetry, cell balancing, and safety disconnects.
The position also plays a key role in supporting the Engineering Manager by training, mentoring, and guiding junior engineers, as well as providing technical leadership on projects. Our products encompass a wide range of custom battery assemblies, which include Battery Management Systems (BMS), battery cells, electronic circuits, electrical connections, and mechanical/thermal structures.
