Sr. Power Management Engineer

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. Power Management Engineer is responsible for building our power management capabilities from the ground up and assisting in developing and tracking power properties to aid with electrical loads/voltage drop development, electrical wiring interconnect system (EWIS) development, aircraft performance trade studies, cost, and more. This position requires an experienced professional with expertise in power analysis/budgeting and control during various phases of aircraft design/development to certification. This position reports to the Head of Systems Engineering and provides technical solutions/guidance for the entire engineering team.

This position will be required to work on-site 5 days a week.

What you can do:

• Leads and participates in system-level trades to ensure the vehicle design meets all physical, electrical, mechanical, and environmental requirements while accommodating the required payload, power, propulsion, thermal, communications, and attitude control system requirements
• Perform electrical system architecture, design and analysis
• Conduct advanced design power estimation to develop preliminary power estimates to support advanced design proposals, prototyping efforts, trade studies, etc.
• Perform estimation, calculation, and develop methods of measurement for verification of power requirements for LRUs, components, assemblies, and complete systems.
• Develop the analysis methods and tools for power management
• Estimate, calculate, and verify mass properties of LRUs, components, assemblies, and complete systems in support of trade studies and drawing/component release
• Manage/perform testing of aircraft wiring harness including bonding and grounding
• Work with the broader engineering team to conduct multi-disciplinary trade studies to guide through design decisions
• Generate and maintain power reports to key stakeholders of various cross-functional teams
• Develop, support, and execute test plans to verify power properties (voltage drops, current distribution, on/off power timing, power quality, etc.)
• Track, maintain, and own power distribution inside a database
• Partner with PMO organization to execute build plan
• Requires up to 10% of domestic and international travel
• Other duties as assigned
