Sr. Electrical Engineer

Job Title

Pay Range: $55hr - $60hr

• 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.
• Hands-on board bring-up and debug experience with standard EE test equipment.
• Strong experience with communication interfaces:
  Ethernet (100
  
  Base-T1, 1000
  
  BASE-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.

• 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.
• Execute electrical design for PCBAs supporting robotic actuator and manipulation systems — including schematic capture, layout, component selection, subsystem architecture, and design for signal integrity, manufacturability, and testability. Design in Altium.
• 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.
• Collaborate with PCB fabrication vendors — stackup selection, DFM review, material trade-offs, Gerber release coordination, and alternate vendor sourcing across multiple concurrent builds.
• Perform board bring-up, functional verification, root cause analysis, and debug using standard lab equipment (oscilloscope, logic analyzer, multimeter, soldering/rework tools).
• Partner with firmware engineers on hardware-software co-development, peripheral interface definition, and BSP bring-up.
• 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).

• Experience with signal integrity and power integrity analysis tools (HSpice, ADS, SIwave) and package-level delay analysis using IBIS/S-parameter models.
• Experience with IMU/inertial sensor integration and low-noise analog front-end design.
• Experience with tactile sensor interfaces.
• Experience with semiconductor vendor technical engagement for component evaluation and design support.
• Experience working with contract manufacturers on DFM review and production test development.
• Familiarity with functional safety hardware mechanisms (watchdogs, voltage monitors, safe-state circuits, redundancy).
