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. BMS Engineer (HiL) is responsible for HW and SW/FW test strategy, verification, and validation of full BMS to be used in the Energy Storage System (ESS) by HiL and custom test methods. The role will collect requirements, develope test architecture and infrastructure for HiL and other test systems. The position works closely with other HW / SW / Cell Engineers within the Battery team, as well as other multi-functional team members to develop test requirements, share findings, and successfully release designs.

What you can do:

  • Develop high-level and detailed BMS HW/ SW integrated test environment & architecture
  • Develop System level test strategy, test cases, and test plan for functional and certification requirements per standards
  • Provide guidance to battery system architects & designers from DFT and test coverage perspective
  • Develop HIL test system and integration with Simulink environment, along with developing test cases
  • Communicate and provide solutions for challenges within the system
  • Select test equipment and implement verification and validation test processes
  • Use HIL system to verify BMS HW, SW and Algorithms at system level
  • Develop Test scripts for BMS HW testers and Regression tests of ESS or Modules for BMS validation
  • Working with HW and manufacturing teams on testing, validation, and factory build support
  • Test BMS HW for sophisticated HW/FW interlaced tests to support BMS EE design Engineers
  • May require up to 10% of domestic and international travels
  • Other duties as assigned

What you can contribute:

  • Bachelor’s degree in Electronics or Electrical Engineering with software engineering focus
  • A minimum of 3-5 years’ experience in HV battery testing and validation using HIL systems in automotive, consumer, or aerospace industry (an equivalent combination of education and experience may be considered)
  • Excellent understanding of functional safety critical testing
  • Expert level experience in specifying, installing, and efficiently using test infrastructure and HIL system for functional verification of HW/FW/SW/Algorithms
  • Excellent programming skills in C, C++, MATLAB, Simulink, and scripting tools like Python
  • Good understanding of SPI, Ethernet, and CAN
  • Knowledge of interfacing HIL system with Simulink based battery models and Realtime RT or NI Test stand-based environments.
  • Familiarity with safety critical component testing requirements
  • Ability to develop collaborative networks
  • Understanding of DO-178C / DO254A/ DO 160G compliance for HW/ SW development and testing is a plus
  • Excellent technical communication and ability to interpret data for resolution and decision-making
  • Proactive delivery of communication and follow-up
  • Excellent organizational skills and attention to detail
  • Successful ability to work both independently and within a team
  • Self-motivated and forward-thinking personality
  • Proficiency with MS Office Suite specifically for data analysis, document creation and reporting

You may also be able to contribute:

  • M.S./PhD in related engineering field preferred
