BMS Electrical Engineer - HW Design

Fremont, CA


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:

BMS Electrical Engineer, HW Design, focuses on design & development of HV distribution HW and electrical systems at Module level and Pack level from concept to completion for our Energy Storage Systems (ESS). The role is responsible for detailed EE HW design, design analysis, prototype verification and production support for testers and product manufacturability. The engineer collaborates with other BMS HW / 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:

  • Develop and release requirement specification for HV Electrical systems and electronic PCBAs
  • Design & release of analog and mixed circuit-based schematics, HV Electrical systems & PCBAs using Altium or equivalent tool set
  • Simulate battery electrical / electronic circuit simulation for design compliance using pSpice / MATLAB / Simulink or other tools
  • Select Electronic, electrical and IC parts to meet performance goals, specifying and working with suppliers to develop custom parts
  • Develop and Release requirements for OTS components to be used in HV electrical systems and PCBAs
  • Analyze the schematic and layout designs with simulation tools and calculations to verify its conformance to the design requirements
