Senior Electrical Engineer

Role Name: Sr. Electrical EngineerLocation: Sunnyvale, CA (Onsite)Duration: ContractJob Description:8+ years of experience in PCBA-level circuit design for robotics, industrial, automotive, or consumer electronicsExperience reviewing designs produced by external engineering teams or ODMs and providing technical feedback on component selection and design trade-offsProficiency with Altium Designer — schematic capture and PCB layoutExperience with subsystem architecture and high-level electrical design for multi-board embedded systemsStrong experience with communication interfaces: Ethernet (100Base-T1, 1000BASE-T), USB, MIPI CSI, SPI, I2C, CAN-FDExperience with EtherCAT hardware architecture — daisy-chain topology, PHY selectionExperience with power architecture design — switching regulators, LDOs, power sequencing, high-current distribution, PMIC integrationExperience with motor driver circuits, gate drivers, or power stage design for BLDC actuatorsExperience managing PCB fabrication vendors — stackup review, DFM, material availability, and multi-vendor coordinationExperience with signal integrity fundamentals — constraint development, impedance control, timing budget analysisAbility to work independently on multiple concurrent board designs at different stages with minimal supervisionContribute to system-level electrical architecture (block diagrams, interface definitions, voltage domains) for multi-board robotic platforms spanning compute, motor control, sensing, and communication subsystemsReview schematics produced by external design partners (ODMs, contract engineering firms), validating component selection and design trade-offs, and flagging misalignment with the system architecturePerform 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 boardsDesign 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 issuesPerform 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 reportsSupport multiple boards simultaneously at different NPI stages (schematic, layout, fab, bring-up)Thanks & RegardsBhavesh Sharmabhavesh@applabsystems.com
