Note: The job is a remote job and is open to candidates in USA. 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)
