Position Overview:
As a Level 3 Senior Hybrid Powertrain Integration Engineer, you are a core member of the execution tier, responsible for leading the electrical and functional integration of the parallel-source hybrid architecture. In this role, you will own the configuration and localized validation of the high-voltage bus bridging the dual battery packs and the internal combustion engine generator unit. You will collaborate closely with multi-disciplinary flight control, power electronics, and systems safety teams to ensure stable power distribution, manage high-voltage boundaries, and advance compliance documentation updates to secure platform maturity.
Key Responsibilities:
• Integrate, analyze, and optimize the high-voltage (400V) DC power distribution network connecting the dual battery strings and generator source.
• Configure and validate multi-source bus isolation strategies, including ideal-diode OR-ing layouts and solid-state non-backfeeding configurations.
• Implement high-speed contactor management paths and tailored pre-charge circuits to safely manage switching transient loads and eliminate damaging inrush currents.
• Evaluate, test, and integrate high-precision ground-fault detection arrays to actively monitor isolation metrics between the high-voltage bus and chassis ground.
• Conduct specialized troubleshooting to diagnose and resolve complex high-power electromagnetic interference (EMI) and cross-talk abnormalities affecting signal line routing.
• Document subsystem verification results, structural integration risks, and component margin reports to keep the master technical baseline current.
Qualifications:
• Deep knowledge of multi-source high-voltage DC power distribution architecture, including isolation barriers, cross-conduction mitigations, and ideal-diode OR-ing frameworks.
• Practical familiarity designing contactor management logic, custom pre-charge circuits, and multi-stage converter interfaces.
• Hands-on exposure utilizing specialized laboratory instrumentation, such as high-voltage differential probes, power analyzers, and vector network analyzers (VNAs).
• Competency in isolating, identifying, and addressing high-power electromagnetic interference (EMI), ground loops, and signal-integrity cross-talk over complex wiring routing structures.
• Demonstrated history working with multi-channel battery management networks, active or passive balancing loops, and automatic isolation tracking units.
• Strong team collaboration habits and cross-functional technical communication skills required to coordinate design boundaries across flight controls, safety, and mechanical groups.
Education:
• Bachelor's or Master's degree in Electrical Engineering, Aerospace Engineering, Mechatronics, or a related technical discipline.
Physical and Mental Requirements:
• Standing and sitting for extended periods of time,
• Lifting up to 25 pounds in a safe and prudent manner,
• Ability to work and communicate well with other employees and management, customers, visitors, vendors.
• Ability to perform work utilizing manual dexterity of the hands,
• Ability to push, pull, bend, stoop, reach above and below shoulders, and full use of upper extremities,
• Ability to easily move through an approximately 25,000 square foot warehouse building,
• Ability to read, write, and understand French,
• Correctable vision and hearing.
This job description is not intended to be all-inclusive, and the employee may also be asked to perform other reasonably related job duties as assigned by their immediate supervisor as required.
The pay range for this role is:
95,000 - 120,000 CAD per year (Jaunt Air Mobility Canada)
