Job Description We are seeking a Senior Electrical Engineer contractor to support robotics hardware development within Amazon's Industrial Robotics Group. You will contribute to system-level electrical architecture across multi-board robotic platforms, execute board designs from schematic through bring-up, and provide technical review of external design partners' schematic and layout work as directed by FTE engineers. You will perform design trade-off analysis MCU/SoC selection, interface topology, power architecture, and sensor integration across multiple concurrent projects, working with minimal supervision alongside a small, fast-moving hardware team led by full-time Amazon engineers.

Key Responsibilities-

• Contribute to system-level electrical architecture (block diagrams, interface definitions, voltage domains) for multi-board robotic platforms spanning compute, motor control, sensing, and communication subsystems
• Review schematics produced by external design partners (ODMs, contract engineering firms), validating component selection and design trade-offs, and flagging misalignment with the system architecture
• Perform MCU/SoC architecture trade studies and component selection analysis (e.g., evaluating ARM Cortex-R/M MCUs, EtherCAT port constraints, package options, peripheral availability) across motor control and sensor interface boards
• Design and review PCB layouts for multi-layer boards with high-speed digital interfaces (Ethernet, GMSL, USB, MIPI CSI-2, CAN-FD), ensuring impedance control, power integrity, and EMC compliance. Perform layout for simple-to-medium boards or simple-to-medium changes on complex boards (in Altium), and coordinate with external layout houses on PCB layout execution for complex PCBs.
• Design power distribution systems including DC-DC converters, LDOs, power sequencing, load switches, and protection circuits for multi-voltage robotic subsystems; debug PMIC behavior and perform root-cause analysis on power delivery issues
• Perform board bring-up, functional verification, root cause analysis, and debug using standard lab equipment (oscilloscope, logic analyzer, multimeter, soldering/rework tools)
• Manage design documentation including block diagrams, schematics, BOMs, design rationale, constraint files, and test reports
• Support multiple boards simultaneously at different NPI stages (schematic, layout, fab, bring-up)

Required Qualifications-

• 8+ years of experience in PCBA-level circuit design for robotics, industrial, automotive, or consumer electronics
• Experience reviewing designs produced by external engineering teams or ODMs and providing technical feedback on component selection and design trade-offs
• Proficiency with Altium Designer schematic capture and PCB layout
• Experience with subsystem architecture and high-level electrical design for multi-board embedded systems
• Strong experience with communication interfaces: Ethernet (100Base-T1, 1000BASE-T), USB, MIPI CSI, SPI, I2C, CAN-FD
• Experience with EtherCAT hardware architecture daisy-chain topology, PHY selection
• Experience with power architecture design switching regulators, LDOs, power sequencing, high-current distribution, PMIC integration
• Experience with motor driver circuits, gate drivers, or power stage design for BLDC actuators
• Experience managing PCB fabrication vendors stackup review, DFM, material availability, and multi-vendor coordination
• Experience with signal integrity fundamentals constraint development, impedance control, timing budget analysis
• Ability to work independently on multiple concurrent board designs at different stages with minimal supervision Buy Rate Vendor " Bill rate should be aligned with current market standards.
