Senior Power Electronics Engineer

Sharkey Motion LLC is engineering proprietary motion control hardware. They require a senior electrical engineer to design the power stage, logic board, and encoder interface for a direct-drive servo while collaborating closely with mechanical engineers.

Responsibilities:

• Design the power stage, logic board, and encoder interface for a direct-drive servo
• Work closely with the mechanical engineer to ensure your PCB layout aligns with the physical thermal dissipation paths of the sealed housing
• Design ultra-compact motor drive circuitry capable of handling high continuous phase currents within a severely restricted physical footprint
• Deep knowledge of wide-bandgap semiconductors (SiC/GaN), gate drive isolation, and high-temperature component selection
• Ability to map critical heat-generating components to specific physical locations on the PCB to align with the mechanical engineer's thermal dissipation paths
• Experience implementing industrial communication protocols (e.g., EtherCAT, CANopen) and standard encoder interfaces (e.g., BiSS-C, SSI)
• Deep, practical understanding of UL 61800-5-1 insulation coordination, including exact creepage and clearance math
• Layout strategy heavily optimized for parasitic inductance minimization, gate driver loop optimization, and EMI reduction to pass FCC Part 15 Subpart B
• 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)
