Design differential-mode and common-mode filters for high-voltage applications.
Design failure detection and protection systems for high-voltage wide bandgap devices.
Manage the complete lifecycle of electronics design, including analysis, schematic capture, printed circuit board layout, component selection, and design verification.
Conduct formal design reviews, Failure Modes and Effects Analysis, and laboratory validation of power electronic systems.
Lead root-cause investigations of failures and define corrective actions, coordinating cross-functional teams and applying structured problem-solving methodologies.
Deliver technical reports and design documentation to support certification activities and regulatory approvals.
Ensure adherence to internal standards and applicable aviation industry regulations.
Contribute to the advancement of departmental technologies, capabilities, facilities, and processes.
Provide technical leadership, guidance, and mentorship to junior engineers.

Desired Qualifications

Experience applying silicon carbide metal-oxide-semiconductor field-effect transistors in high-voltage, high-altitude environments.
Knowledge of finite-element method simulation tools such as Ansys Maxwell.
Experience with double-pulse tests, metal-oxide-semiconductor field-effect transistor thermal-path characterisation, and motor integration tests.
