• Undertake analysis of three-phase inverters, including dynamic switching characteristics, efficiency, and thermal performance.
• Design differential 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, PCB layout, component selection, and design verification.
• Conduct formal design reviews, FMEA, and laboratory validation of power electronic systems.
• Lead root-cause investigations of failures and define corrective actions, coordinating cross-functional teams with structured problem-solving methodologies.
• Deliver technical reports and design documentation to support certification activities and regulatory approvals.
• Ensure adherence to Evolito 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 within the team.
