Senior Electrical Firmware Engineer

HCLTech is looking for a highly talented and self- motivated Senior Electrical Firmware Engineer to join it in advancing the technological world through innovation and creativity.

Job Title: Senior Electrical Firmware Engineer

Job ID: 126781

Position Type: Full-time

Location: Sunnyvale, CA / Onsite

Role/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)..

Minimum Requirements

• 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
• 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))
