Embedded Software Engineer for Battery and On-board Charge Software

The Embedded Software Engineer for Battery and On-board Charge Software will apply their knowledge of RTCA DO-178C, best practices for real-time safety-critical embedded software development, and embedded C skill set to specify, architect, design, implement and integrate the embedded software for BETA's airborne systems. The ideal candidate will have a broad knowledge of embedded software development, from bare-metal board bring-up and understanding of microcontroller timing and execution characteristics to high-level software specification and design methods and techniques.

How you will contribute to revolutionizing electric aviation:

• This position is primarily a software role with required ability to understand and troubleshoot hardware.

• Become familiar with existing software and hardware for the on-aircraft charging system and battery management 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.)

Above and Beyond Qualifications that will distinguish you: (preferred qualifications):

• Master's degree or equivalent experience

• Experience with EV charging standards:

• Experience with powerline communications using HomePlug GreenPhy 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

Physical Demands and Work Environment:

• This position will be based on-site at Beta's facilities in South Burlington, Vermont.

• Ability to transport yourself to various BETA locations around Burlington as needed.

• Able to work in a dog-friendly and open-office environment
