Careers

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.

Role Overview & Context

Sharkey Motion LLC is developing a highly integrated, next-generation direct-drive servo system. We require a precision mechanical engineer to design a custom 6061 aluminum housing that serves as both the physical envelope and the primary thermal dissipation path for high-wattage internal components.

Key Technical Requirements

• DFM/DFA: Extensive experience designing complex enclosures optimized for external CNC machining. Must understand cutter limitations and cost-effective fixturing.
• Precision Tolerancing: Deep expertise in GD&T, designing for strict press-fit tolerances, and specifying precision bearing seats.
• CAE & Thermal Management: Proven ability to conduct thermal FEA and design effective passive heat sinking for enclosed, high-current switching electronics.
• Environmental Sealing: Must design for strict IP65/IP67 ingress protection, including dynamic shaft sealing and static O-ring grooves.
• Tooling: Expert-level proficiency in SolidWorks. Ability to generate flawless STEP files and complete 2D manufacturing drawings.

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 CAD and mechanical IP is fully assigned to Sharkey Motion LLC.

Role Overview & Context

As Sharkey Motion LLC transitions from CAE simulation to physical validation, we will require a dedicated prototype machinist to cut initial housings and test fixtures. This role will work directly with the mechanical engineer's STEP files to refine toolpaths, validate GD&T press-fit tolerancing, and execute rapid design iterations prior to LRIP scale-up.

Anticipated Requirements

• CAM Programming: Ability to independently generate highly optimized toolpaths from provided STEP files.
• Precision Machining: Deep expertise operating 3-axis and 5-axis CNC mills for complex 6061 aluminum geometries.
• Strict Tolerancing: Proven experience hitting tight GD&T callouts, specifically for bearing seats and motor housing assemblies.
• Physical Demands: Ability to safely and independently lift, manipulate, and fixture metal stock weighing up to 50 lbs; stand for extended periods and safely operate heavy manual and CNC machinery; and sufficient manual dexterity to precisely handle measurement tools (e.g., calipers, micrometers) and delicate cutting tools.
