Senior Power Electronics Engineer

Role Overview & Context
Sharkey Motion LLC is engineering proprietary motion control hardware. We require a senior EE to design the power stage, logic board, and encoder interface for a direct-drive servo. You will work closely with the mechanical engineer to ensure your PCB layout aligns with the physical thermal dissipation paths of the sealed housing.
Key Technical Requirements
Power Density: Must design ultra-compact motor drive circuitry capable of handling high continuous phase currents within a severely restricted physical footprint.
Component Expertise: Deep knowledge of wide-bandgap semiconductors (SiC/GaN), gate drive isolation, and high-temperature component selection.
Thermal-Electrical Co-Design: Ability to map critical heat-generating components to specific physical locations on the PCB to align with the mechanical engineer's thermal dissipation paths.
Signal Interfaces: Experience implementing industrial communication protocols (e.g., EtherCAT, CANopen) and standard encoder interfaces (e.g., BiSS-C, SSI).
Regulatory Compliance: Deep, practical understanding of UL 61800-5-1 insulation coordination, including exact creepage and clearance math.
Signal Integrity: Layout strategy heavily optimized for parasitic inductance minimization, gate driver loop optimization, and EMI reduction to pass FCC Part 15 Subpart B.
Tooling & BOM: Mastery of Altium Designer or KiCad. Ability to construct a highly resilient Bill of Materials prioritizing high-availability components from US distributors (e.g., DigiKey, Mouser).
Operational Expectations
This is a discrete, milestone-driven 1099 NRE contract. Prior to project kick-off and technical brief delivery, the selected candidate must execute a strict Confidential Information and Inventions Assignment Agreement (CIIAA) ensuring all generated schematic and layout IP is fully assigned to Sharkey Motion LLC.
