About the role

  • Design and build high voltage, high power density power electronics converter products for eVTOL applications
  • Develop and analyze electrical architectures and power converter (DC-DC) topologies, and ensure system functions, performance, safety and reliability requirements are achieved
  • Responsible for all aspects of power electronics designs required in an all-electric aircraft, from components to circuits, modules and system integration
  • Leads new designs from conception into production while working with a multidisciplinary team
  • Start to finish ownership of hardware – from specification to design, component selection, modeling, prototype, product build, verification testing, safety and reliability validation and manufacturing
  • Design electronic power supply and sensing circuits
  • Schematic, layout and PCB assembly design and review
  • Design and carry out prototype verification tests for proof of concept
  • Analyze test data and reports to determine if the design meets functional and performance specifications
  • Troubleshoot and help root cause any issues that occur in the prototype line
  • Continuous improvement of converter product performance (weight, size, functions and features, reliability, DFM, DFT)
  • Work with manufacturing, supply chain, quality teams to ensure efficient and high yield production of converter products
  • Collaborate with cross-functional teams to meet product safety and reliability requirements
  • Design, optimize, build and test custom magnetics (high-frequency transformers, inductors) for aerospace power electronics systems
  • Support EMC and environmental stress testing and failure / fault analysis for various power electronics modules and systems

Requirements

  • BS Degree in Electrical Engineering with 10+ years or MS with 8+ years of experience in related fields
  • Sound knowledge and hands-on experience in traditional and modern power electronic technologies
  • Low power and high power DC-DC topologies, gate driver, modulation techniques and control theories
  • Inverter technology for variable speed motor drive, including topologies and PWM techniques
  • Familiarity with both wide-band-gap and silicon power semiconductor devices
  • Passive power devices, e.g. inductors, capacitors, resistors and transformers
  • Experience in design, build, manufacturing and testing of custom magnetics (high -frequency transformers, inductors)
  • Power electronics system architecture design and hardware integration
  • Power converters and motor drive (AC-DC, DC-DC, DC-AC) control technologies
  • Microcontrollers and multiple serial protocols (UART, CAN, SPI, I2C, etc.)
  • Sensor technology and implementation
  • Gate drive design
  • Experience with high voltage (400V-1000V) DC-DC converter products, familiar with high-frequency and soft-switching technologies
  • Experience in using schematic capture tools (e.g. Altium Designer or Allegro)
  • PCB layout experience is strongly preferred
  • Experience in using electrical circuit simulation software (e.g. Matlab/Simulink, PLECS, LTspice)
  • Experience performing circuit design analyses such as worst-case circuit analysis, fault analysis, and lifetime estimation
  • Master of all types of lab instruments: oscilloscope, power supplies, electronics loads, function generators, network analyzer, EMC analyzers etc.
  • Excellent organizational and communication skills
  • Archer is unable to provide work visa sponsorship for this position at the present time
  • Bonus: Hands on experience with DO-160G testing and DO-254 development
  • Bonus: Ph. D. in power electronics
  • Bonus: Embedded firmware development experience
  • Bonus: Experience with 50kW-200kW inverters at 400V-1000V
  • Bonus: Passion for aviation and eVTOLs
