Electrical Engineer

About The Position

We're looking for an exceptional Senior Electrical Engineer to design and own the embedded devices and internal tools that power the next generation of Noble Machines' general-purpose robots. This is a high-impact, high-ownership role: you'll be the person other engineers rely on for reliable hardware and the tooling that makes their own work faster and safer. You'll work across the full stack — from schematic design and layout to bring-up to field validation — building electronics that have to work the first time, every time, in environments where failure isn't an option.

Requirements

6+ years of professional experience in electrical engineering, ideally in robotics, embedded systems, automotive, or consumer/industrial electronics.
Strong hands-on PCB design experience (multi-layer, mixed-signal), using tools such as Altium or equivalent.
Deep familiarity with embedded systems: microcontroller-based design, firmware/hardware interfaces, and common communication protocols (I2C, SPI, CAN, UART, Ethernet, USB).
Track record of taking hardware from concept through prototyping, validation, and production.
Proven experience building test fixtures, debug tools, or developer-facing hardware/tooling.
Comfortable with root-cause debugging of hardware and firmware issues using lab equipment.
Strong communication skills — you'll be documenting designs and mentoring others, not just building in isolation.
Bachelor's, Master's, or PhD in Electrical Engineering or a related field.

Nice To Haves

Experience with power electronics: DC/DC converters, motor drives, battery management systems.
Background in legged or humanoid robotics, or other complex electromechanical systems.
Familiarity with ROS 2 or embedded Linux/RTOS environments.
Experience designing for ruggedized or explosion-proof/hazardous-area electronics.
Sensor integration experience (IMUs, encoders, force/torque sensors, LIDAR).

Responsibilities

Own electrical design end-to-end for embedded devices and internal developer tools — schematics, PCB layout, bring-up, and validation — supporting the robot's compute, sensing, and communication subsystems.
Design and build test fixtures, debug tooling, and diagnostic hardware that accelerate development and validation across the broader engineering team.
Architect embedded electronics for reliability in harsh field conditions (dust, vibration, temperature extremes, power transients common to construction, mining, and energy sites).
Select and integrate microcontrollers, sensors, and communication interfaces (I2C, SPI, CAN, Ethernet, USB) to support real-time control and data acquisition.
Collaborate closely with mechanical, firmware, and software teams to ensure electrical designs integrate cleanly with the full robot system.
Own component lifecycle management and vendor relationships, including PCBA fabrication and assembly partners.
Develop and execute validation and test plans (DVT/PVT), using lab equipment (oscilloscopes, logic analyzers, power supplies) to verify performance, safety, and reliability.
Mentor other engineers on hardware design, documentation, and debugging best practices as the team grows.
