Sr. Power Electronics Hardware Engineer at odys aviation | LAYIQ

Architect and design SiC-MOSFET-based motor drives, active rectifiers, and DC/DC converters operating at switching frequencies greater than 20–40 kHz, with focus on power density, efficiency, and reliability for airborne applications.
Lead schematic capture and PCB layout (Altium, Cadence, or equivalent) for high-voltage, high-current power stages, including controlled-impedance routing, creepage and clearance per aerospace standards, and partitioning of power, signal, and gate-drive domains.
Design gate-drive circuits tailored to SiC device physics, including isolated drivers, dv/dt and di/dt management, desat and short-circuit protection, miller-clamp strategies, and dead-time selection in coordination with the controls engineer.
Design magnetic components - DC-link inductors, common-mode and differential-mode chokes, current sensors, and isolation transformers - including core selection, winding strategy, loss budgeting, and saturation analysis for high-frequency operation.
Develop DC-link architecture and capacitor banks, including ripple-current budgeting, ESR/ESL management, lifetime analysis, and pre-charge/discharge circuitry.
Lead thermal design of converter assemblies, including heatsink and cold-plate selection, junction-to-coolant thermal stack-up, transient thermal analysis, and coordination with mechanical engineering on cooling integration.
Design EMI/EMC mitigation at the hardware level - input/output filters, shielding strategy, grounding architecture, and layout-level techniques - to meet DO-160 conducted and radiated emissions requirements.
Define protection architecture including overvoltage, overcurrent, overtemperature, ground-fault, and arc-fault detection circuitry, and partition responsibilities between hardware interlocks and firmware-level FDIR with the controls team.
Specify and qualify power semiconductors, magnetics, capacitors, sensors, and connectors; drive component derating analyses, supplier evaluations, and second-source strategies appropriate for aerospace volumes.
Lead board bring-up, double-pulse testing, and converter characterization on bench and dyno; correlate measured switching behavior, losses, and thermal performance with simulation and iterate the design to close gaps.
Collaborate with the controls/software engineer to define sensor placement, current/voltage feedback signal conditioning, and ICD-level interfaces; ensure hardware exposes the observability needed for FOC, sensorless operation, and diagnostics.
Produce deliverables aligned with DO-254, DO-160, and ARP4754B standards, including hardware design specifications, schematic and layout review packages, derating and stress analyses, FMEA/FMECA, and verification evidence.
