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 MCUSoC selection, interface topology, power architecture, and sensor integration across multiple concurrent projects, working with minimal supervision alongside a small, fast-moving hardware team., 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 MCUSoC architecture trade studies and component selection analysis (e.g., evaluating ARM Cortex-RM 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, solderingrework 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)
