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.
