Sr. Electrical Engineer

$55 - $60 per hour

Cynet Systems

Job Overview:


Pay Range: $55hr - $60hr


Requirement/Must Have:

  • 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 (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.
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.
  • 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).
Nice to Have:
  • 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).
