Sr. Power Electronics Engineer

Supernal is at the forefront of creating emerging mobility solutions that will foster the development of human-centered cities. We are designing a completely new electric vertical take-off and landing (eVTOL) aircraft tailored to the mobility needs of future cities. This allows passengers a seamless intermodal journey that safely transports them to their final destination. We fuse research in autonomy, robotics, aviation and services to define a new category of mobility for the world’s communities. We believe in creative thinking and collaboration to help build a better mobility experience for everyone, improving people’s ability to move – whether for work or play.

What we do:

The Sr. Power Electronics Engineer is responsible for hardware development of the electric motor controller power electronics and will be involved closely with control algorithm and software development. This position will work closely with Battery Technology, Flight Controls, Test & Evaluation, and Airframe teams.

This position will be required to work on-site 5 days a week.

What you can do:

• Lead design and development of motor inverter power electronics. This includes, but is not limited to, defining power conversion topology, control interfaces and circuitry, and developing control algorithms.
• Collaborate closely with suppliers on design evaluation and validation of inverter hardware in order to meet technical specifications and program timelines
• Assess development risks and coordinate mitigation strategies
• Lead simulation and analysis efforts of electric drives and high voltage power electronics
• Work with system architecture and safety teams to develop requirements and specifications for motor control system and cascade down to components of the embedded systems
• Define and mature mechanical, electrical, and communication interfaces with aircraft systems to include airframe, wiring, electric motors, and vehicle management systems
• Work closely with the motor control team to outline controller requirements, develop and implement control strategies, and tune controller algorithms to optimize performance
• Assist in developing the safety of flight artifacts, including system safety assessments, fault trees, and FMEAs
• Provide hands-on support to model-in-the-loop (MIL), Hardware-in-the-Loop (HIL), and Software-in-the-Loop (SIL) test execution and troubleshooting
• Other duties as assigned

What you can contribute:

• Bachelor’s degree in Electrical Engineering or other related field required; Master’s degree preferred
• Minimum five (5) years of relevant experience (an equivalent combination of education experience may be considered)
• Advanced knowledge of power electronics products for EV powertrain: AC/DC converters, battery chargers, inverters, EMI filters, high voltage power distribution and others
• Advanced understanding of EMC (electromagnetic compatibility) standards
• Advanced understanding of electrical engineering protocols and standards
• Advanced knowledge of DVP&R and DFMEA
• Knowledgeable in WBG, IGBT, and MOSFET technologies
• Knowledgeable in power converter topologies
• Strong skills in the ability to solve difficult problems related to power electronics components/devices
• Strong ability to identify and communicate risks, and drive issues to closure
• Eagerness to expand skills and knowledge into electric aviation propulsion systems
• Excellent verbal and written communication skills
• Excellent organizational skills and attention to detail
• Must have the ability to independently prioritize and accomplish work within time constraints

You may also be able to contribute:

• Experience with qualification of safety-critical software to DO-178B preferred, but hands-on experience with qualification to ISO26262 ASIL D is acceptable
• Experience with full life-cycle of electric motor control development, qualification, production and product support preferred
• Industrial experience in automobile, aviation, aerospace industry preferred
• Experience with permanent magnet synchronous electric motor design and development preferred
• Experience with 500-1200 VDC systems is preferred
• Experience working in aviation industry is preferred
• Experience working with regulatory agencies is preferred
