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:

Sr. BMS Engineers – HW Design focus on architecting, design & development of BMS HW and electrical systems at Module level and Pack level from concept to completion for our Energy Storage Systems (ESS). They will be responsible for detailed HW design, design analysis, prototype verification and production support for testers and product manufacturability. They will work with other SW / Algo / Cell Engineers in Battery team and other multi-functional team members to develop SW requirements and to support integration testing at Powertrain, ESS system, or Cell module level.

What you can do:

  • Responsible for the overall architecture and validation of high voltage BMS at module and system level
  • Responsible for functional safety and redundancy architecture of HV BMS
  • Responsible for interface definition development between peer sub-systems
  • Develop architectures for HV BMS for new and innovative ESS solutions
  • Ensure requirement traceability between BMS and higher and lower-level systems
  • Develop and release board level and system level requirement specifications
  • Simulate ESS and BMS using Matlab/Simulink and linking with aircraft level models and HIL systems for parallel validation of BMS functionality
  • Analyze the schematic and layout designs to verify its conformance to the design requirements.
  • Conducting and participating in design reviews, incorporating team feedbacks, and releasing design documents.
  • Develop validation requirements for HV BMS and approving validation results confirming agreed upon performance
  • May require up to 15% of domestic and international travels
  • Other duties as assigned

What you can contribute:

  • B.S. in a relevant engineering field
  • 5-8 years of demonstrated experience in BMS hardware or mixed signal & power electronics hardware development for Industrial, automotive, large consumer products or aerospace applications (An equivalent combination of education and experience may be considered)
  • Experience in ECAD tools like Altium for Schematics and layout
  • Ability to design HW to meet Environmental, EMI/EMC, thermal, shock & vibration
  • Experience in conducting and documenting Tolerance analysis, Part stress analysis, Safety Hazard Analysis, FMEA, and FTA
  • Excellent skills required in technical communication, and reliance on data for issue resolution and decision making
  • Excellent organizational skills, team-oriented thinking, and attention to detail
  • Self-motivated and forward-thinking personality
  • Proactive delivery of communication and follow up
  • Must have the ability to independently prioritize and accomplish work within time constraints

You may also be able to contribute:

  • Master’s degree or PhD in chemical engineering, material science/engineering, physics, chemistry, or related engineering fields
  • Demonstrated experience in HW development for HV BMS
