We are looking for passionate individuals who believe in their abilities and the impact they can make on the products they work on. As a Senior Power Electronics Hardware Engineer, you will join the Power Electronics (PWX) Hardware development group, where you will be responsible for the design and development of power converters from inception to production. This role involves validating designs, creating engineering specifications, and producing engineering documents. You will be engaged in topology selection, conducting design reviews, designing schematics, selecting components, creating layouts in Altium, and preparing release documentation for production. Additionally, you will conduct reliability studies and assessments while supporting product manufacturing and testing. This position is based in-person at the Innovation Hub located in Stone Mountain, Georgia. The ideal candidate will be agile, professional, and comfortable in a rapidly changing environment. Trustworthiness and a strong work ethic are essential, as you will be expected to work diligently even when not under direct supervision. In this role, you will design single-phase and three-phase bidirectional inverters with a focus on achieving maximum efficiency and cost-competitive designs. You will need to understand marketing specifications to select appropriate topologies that meet cost, efficiency, and performance targets. Your responsibilities will also include high voltage power semiconductor selection, understanding switching behavior, calculating losses in converter/inverter systems, and performing reliability and cost analyses with various semiconductor technologies. You will need to have a good understanding of relevant standards such as UL1741, IEC62019, and IEC 60730, and apply this knowledge to ensure compliance during the design process. You will also be responsible for designing with both isolated and non-isolated topologies, with a major focus on non-isolated designs, and implementing active and passive cooling systems. Ownership of power layout techniques to reduce noise, EMI, and EMC will be crucial, as will your ability to conduct pre-compliance testing in-house and at EMI EMC laboratories. A deep understanding of magnetics and the ability to design and build magnetics for prototype evaluation will also be required. Testing and troubleshooting complex problems under pressure while providing feasible short- and long-term solutions will be part of your daily tasks. Good communication and documentation skills are essential, as is the ability to work both independently and as part of a small interdisciplinary team.
