Job Description

Sr. Battery Module/Pack Engineer

Fremont, California


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:

Battery Module/Pack Engineer is responsible for designing and prototyping high voltage and high-power battery systems in electrified aircrafts. The role is actively involved in the ESS development process to include conceptual designs, selection of components, prototype builds, and releasing designs for manufacturing. This role works closely with battery system technologists to integrate and advance key technologies of the design, and DAEs, test engineers and product integration engineers to ensure a robust ESS is designed, built, and incorporated in the eVTOL aircraft.

What you can do:

  • Design modules and packs for HV battery system from concept to production
  • Perform analytical and physical assessments of battery system to ensure the design’s robustness, reliability, and requirements
  • Support the engineering tools development to provide trade-off studies between packaging efficiency, thermal, NVH prior to and/or during design phases
  • Responsible for battery systems FMEAs, including safety features
  • Build and contribute to component specifications, verification plans, and other technical documents
  • Document and release designs in the PLM system
  • Conduct prototype builds
  • Collaborate with battery system technologists to develop and to introduce new technologies into current battery modules/packs design
  • Collaborate with battery component suppliers to support new technology development
  • Collaborate with the battery integration team to optimize and improve the battery system design including the thermal control system
  • Collaborate with battery test and validation team on DVP&R activities
  • May require up to 10% of domestic and international travels
  • Other duties as assigned

What you can contribute:

  • Bachelor’s degree in mechanical engineering, electrical engineering or relevant engineering field
  • A minimum of 5-8 years of proven experience in HV battery system design (an equivalent combination of education and experience may be considered)
  • A strong understanding of structural composites, thermal interface materials, thermal barriers, high voltage/high power safety and design for safety
  • Proficiency in CATIA and at least one battery system modeling/simulation suite
  • Excellent understanding of mechanical structures, electrical and thermal analysis of a battery system, especially for high voltage and high-power applications
  • Must have hands-on experience in prototype build high voltage battery packs
  • Proven experience developing engineering tools/processes to support analysis and design
  • Professional knowledge of Lithium-based batteries
  • Experience with DOEs for performance evaluation and hardware test & validation for HV battery pack
  • Proven experience developing engineering tools/processes to support analysis and design
  • Excellent verbal and written communication skills
  • Proactive delivery of communication and follow up
  • Excellent organizational skills and attention to detail
  • Must have the ability to independently prioritize and accomplish work within time constraints
  • Self-motivated and forward-thinking personality

You may also be able to contribute:

  • M.S/PhD in a related engineering field
  • Experience in designing and testing battery systems against DO-160 and DO-311
  • Experience with design for mass production
