Mechanical Design Engineer, Battery Pack

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 Mechanical Design Engineer will lead all aspects of designing the mechanical parts of the battery module and pack components for EVTOL battery systems. These battery systems contain high voltage bussing and insulation, an array of cells with structural, thermal, and electrical interfaces, thermal systems, current collection and welded interconnects, printed circuit boards, wiring harnesses, breathers, and vents, and mitigations for abuse scenarios such as thermal runaway, short circuit, and fluid susceptibility. This role will design these components, validate them at the component and subsystem level, and introduce them into volume manufacturing and service for Supernal's Battery Pack designs.
The Battery Pack Team is responsible for designing and prototyping high-voltage and high-power battery systems in electrified aircrafts. The Mechanical Design Engineer for the Battery Pack is critical to the Energy Storage System (ESS) development process, including conceptual designs, selection of components, prototype builds, and launch designs for volume manufacture. This role works closely with battery systems, test, and product integration engineers to ensure a robust ESS is designed, built, and incorporated into the eVTOL aircraft.
This position will be required to work on-site 5 days a week.
What you can do:

• Design drive components and subsystems, starting from conceptualization and requirements development, all the way through to the production phase
• Select, prove, and implement the application of existing technologies to internal product development and develop new technologies to improve product metrics
• 3D design of complex parts and assemblies in different materials using various manufacturing technologies such as injection molding, stamping, casting, and die-cut sealing solutions
• Release drawing packaging and manufacturing instructions for parts and assemblies, employing high-quality technical communication to prevent misinterpretation and manufacturing issues
• Understand and complete designs to specifications pertaining to mechanical components for HV batteries (dimensional, thermal, dielectric, functional, performance, reliability, survivability, component manufacturing, and interface manufacturing)
• Perform preliminary prototyping, testing, and analysis tasks, as well as provide assistance with more complex analysis and validation testing
• Identify the root cause of prototype, validation, and production issues, and assist in finding appropriate solutions
• Communicate own work to department leadership and cross-functional teams through written and oral presentations
• Travel to Supernal sites for collaboration across teams and to suppliers for technology development, process validation, and issue resolution
• Build relationships with critical cross-functional teams in electrical design, testing, safety, abuse, manufacturing, systems, certification, and airframe
• Up to 10% of domestic and international travel
• Other duties as assigned

What you can contribute:

• Bachelor's degree in mechanical engineering or equivalent required
• Minimum three (3) years of experience in engineering (an equivalent combination of education and experience may be considered)
• Proficiency in strong engineering fundamentals, including mechanics, heat transfer, fluids, and basic circuits
• Ability to design parts, create prototypes, and conduct testing during the development phase
• Proficiency in CATIA or similar 3D modeling system
• 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
• Proficiency with Excel VLOOKUP, pivot tables, MS Office Suite
