Electrical Engineer (Battery Specialist)

Electrical Engineer (Battery Specialist)

We are a fast-growing company with a single lofty goal: to bring personal aviation to the general public. Innovating at the leading edge of electric aviation technology, we have developed BlackFly, the world’s first ultralight all-electric fixed-wing VTOL personal aircraft. Join us in ushering in a new age of aviation.

We are seeking a motivated individual to take on the role of battery specialist within our Electrical Engineering group.

Role Responsibilities

  • Develop an offline state-space lithium-based battery estimation model such as in Matlab/Simulink.
  • Devise and carry out lab experiments to test, tune and refine the model under the full range of operating temperatures, currents, depth of discharge, and cycle count.
  • Implement the model on an embedded MCU which accurately estimates SOC, SOE, and SOP in real-time over the full range of operating conditions for the service life of the battery.
  • Develop a battery characterization test to QC incoming batteries and test new samples.
  • Develop methods to perform a rapid pre-flight check of battery metrics.
  • Define safe operational minimums and maximums for the battery based on experimental results.
  • Depending on experience, assist with charger development and take ownership of BMS.

Minimum Qualifications

  • Undergraduate or graduate degree in Electrical Engineering.
  • Proficient at writing firmware (C/C++) for MCUs in embedded systems.
  • Experience with extended Kalman filter algorithms.
  • Familiarity with battery rapid-test methods such as dynamic response, impedance spectroscopy.
  • Hands-on electronics experience through student teams, co-op, and/or personal projects

Optional Qualifications

  • Circuit design, PCB layout, power electronics, SPI, UART, CAN.
  • Matlab/Simulink and Python experience.
  • Interest in RC planes, quadcopters, or aviation.

Personal Attributes

  • Hard-working, detail-oriented, resourceful, curious and enjoys being challenged
  • Always thinking about how to make things more efficient
  • Thrive in a fast-moving, stimulating, and supportive team environment
