It’s the kind of mission diversity that demands a fresh way of thinking. We began with an early bet on hybrid, when the mobility industry was focused on batteries. We designed, tested, and validated our first 1 MW high-speed generator in 12 months. And then we pushed further, developing systems with greater power density in less time. Today, our Hybrid Power Systems offer outputs ranging from **20 kW** to **4 MW**, with applications in the air or on the ground. One of those applications is **Laila**, an unmanned drone designed for critical logistics and defense missions. With its 100 kW-class onboard Hybrid Power System, Laila can support medical cold-chain transport or serve as an aerial platform for counter-UAS measures. The market interest has been overwhelming: **Over 30** inbound requests from leading US and global manufacturers, and **14+ DoDcontracts**. Our team comes from deep tech and aerospace, with backgrounds spanning drone and aircraft development, high-volume production, and electrified mobility. We operate with urgency and ownership at every level. We validated high-speed generator technology faster than our peers, not because we skipped steps, but because we've been doing this long enough to know which ones matter most. **Creating the future** of power, in the air and on the ground, is a challenge we’ve been training our entire lives for. If that sounds like you, this is the opportunity you’ve been waiting for.  Odys Aviation is at the forefront of developing hybrid-electric aircraft to enable sustainable regional air travel. As the Sr. Power Electronics Hardware Engineer, you will be responsible for the design and development of our SiC-based propulsion power electronics - motor drives, active rectifiers, and DC/DC converters - supporting both the Laila (UAV) and Alta (Hybrid-electric VTOL) programs. This role focuses on hardware design and physical realization. You will be tasked with architecting and delivering high-power-density SiC converter stages from concept through flight hardware, including schematic capture, PCB layout, magnetics, gate-drive and protection circuitry, thermal management, and EMI mitigation. Control algorithms, embedded firmware, and HIL infrastructure will remain with peer engineers; your responsibility is to deliver hardware that meets electrical, thermal, mechanical, and certification targets, and that enables the control system to extract full performance. The primary deliverable is a propulsion power electronics stack that achieves aerospace-grade reliability, hits aggressive power-density and efficiency targets, and is manufacturable, testable, and robust under the full envelope of flight conditions. **Responsibilities** - 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. **Requirements** - BS, MS, or PhD in Electrical Engineering, Power Electronics, or related discipline. - A minimum of 5 years of experience designing high-power motor drives or power converters from concept through hardware bring-up. - Demonstrated expertise in SiC MOSFET-based converter design, including switching behavior, gate-driver design, dead-time effects, parasitic management, and high-voltage protection. - Strong proficiency in schematic capture and PCB layout for high-power, high-voltage systems, with hands-on ownership of multilayer power boards through fabrication and assembly. - Solid magnetics design experience - inductors, transformers, common-mode chokes - including core/winding selection and loss analysis at high switching frequencies. - Working knowledge of thermal management for power electronics, including conduction, convection, and liquid-cooled architectures, and use of thermal simulation tools. - Experience with EMI/EMC design and mitigation, including filter design, layout best practices, and pre-compliance testing. - Hands-on lab proficiency with high-voltage bench work, including double-pulse testing, network analyzers, high-bandwidth oscilloscopes, current probes, and electronic loads, with disciplined high-voltage safety practices. - Working familiarity with PMSM drive topologies and the control-system requirements they impose on hardware (sensor bandwidth, isolation, latency), sufficient to design hardware that supports FOC, sensorless operation, and flux-weakening. - Familiarity with SPICE and converter-level simulation tools (PLECS, LTspice, or equivalent) for device-level and circuit-level analysis. **Preferred Qualifications** - Aerospace or eVTOL powertrain experience, with familiarity in FAA/EASA certification processes. - Experience with DO-254 compliance in a regulated hardware development environment, plus working familiarity with DO-160, ARP4754B, FMEA/FTA, and requirements traceability. - Experience designing converters for high-speed PMSMs, including multi-three-phase architectures, generator-mode operation, and active-rectifier topologies. - Hands-on experience with high-power-density liquid-cooled converter assemblies and integration with airframe cooling systems. - Familiarity with battery-pack interfaces, pre-charge architectures, and contactor/HVIL design for high-voltage DC distribution. - Experience taking power electronics hardware from prototype through DVT, qualification testing (DO-160 environmental, vibration, thermal), and into low-rate production. - Working knowledge of CAN, CAN-FD, and Ethernet hardware interfaces, including isolation and signal integrity for noisy power-electronics environments.
