At BETA Technologies, we apply our intellectual curiosity, passion for aviation, and commitment to sustainability toward a shared mission of revolutionizing electric aviation. Regardless of the position one holds, each team member brings their talent and desire to positively impact the environment and lives of others in a refreshing, vibrant, and inclusive culture.

We are seeking an embedded systems engineer to own the software development and verification for our on-aircraft charge management system. This person will be the technical owner for the embedded aspects of BETA’s Electric Vehicle Charge Controller (EVCC) for CCS charging. The position requires a blend of software, electrical, and battery knowledge and a willingness to explore new ideas and technologies to bring increased performance, reliability and ensure safety standards are met or exceeded.

This person will work closely with our electrical hardware engineers and ground support equipment engineering team to create and integrate a complete charging system for our aircraft.

• This position is primarily a software role with required ability to understand and troubleshoot hardware. Hardware design skills (from scratch) are a plus, but not required.
• Become familiar with existing software and hardware for the on-aircraft charging system. Provide support and improvements for existing hardware and software on aircraft.
• Write system level, software, and hardware requirements for certification-intent aircraft charge controller
• Lead development of new and improved software and implementation/testing on the hardware and in the aircraft.
• Support debugging and testing of hardware and software in a certification environment
• Work with the Ground Support Equipment (GSE) team to provide a seamless charging experience across BETA’s platforms and with 3rd party EVSEs
• Interface with BETA’s supplier partners in charging

• Bachelor’s degree or equivalent experience in electrical engineering, computer science, embedded systems, or related fields.
• Experience and understanding of electrical fundamentals, switching power supplies, electrical isolation/insulation strategies.
• Ability to operate lab equipment including low and high-voltage power supplies, function generators, oscilloscopes, multimeters, soldering irons, etc
• Programming skills in C, C++, and Python
• Experience with software development and debugging for embedded systems
• Experience with version control systems (git, SVN, etc.)

• Master’s degree or equivalent experience
• Experience with EV charging standards:
• Experience with powerline communications using Home Plug Green Phy or similar signal-over-power methods like Power over Ethernet
• Experience with bare-metal embedded systems
• Experience with software development for Linux-based embedded systems
• Experience with CMake-based build environments
• Experience with schematic capture and printed circuit board layout. (KiCAD or Altium preferred)
• Understanding of electrical overcurrent protection coordination and high-voltage insulation
• Experience with circuit simulation software, especially related to power electronics stability, line/load regulation, control system responses, etc. LTSPICE, PSPICE, Matlab/Simulink are a plus
• In-depth knowledge of high-voltage (>800V) designs and isolation boundaries/techniques for power and signal transmission
• Experience with power distribution, high-voltage batteries, motor control, avionics, or cabin conditioning (heating, cooling, defog, de-ice) in aerospace, automotive, or similar setting
• Experience designing and testing for EMI mitigation and EMC
• Experience with common communication protocols including CAN, ARINC-429, RS485, SPI, I2C, UART
• Experience in a production environment in aerospace or similar industry, especially related to electronic assemblies and printed circuit boards in in Part 23 or Part 25 aircraft
• Pilot’s license or an interest in flying

• This position will be based on-site at Beta’s facilities in South Burlington, Vermont.
• Ability to transport yourself to various BETA locations…
