Mechatronics Engineer

About Noble Machines

Noble Machines (formerly Under Control Robotics) builds multipurpose robots to support human workers in the world's toughest jobs—turning dangerous work from a necessity into a choice. Our work demands reliability, robustness, and readiness for the unexpected—on time, every time. We're assembling a mission-driven team focused on delivering real impact in heavy industry, from construction and mining to energy. If you're driven to build rugged, reliable products that solve real-world problems, we'd love to talk.

Position Overview

At Noble Machines, building is a team sport. As a Mechatronics Engineer, you’ll take ownership of the low-level control stack that powers our multipurpose humanoid robots. You’ll design, implement, and optimize real-time motor control and fieldbus communication systems—with a strong focus on EtherCAT driver development and deterministic distributed control.

This role sits at the intersection of hardware and software. You’ll work closely with controls, embedded, and mechanical teams to ensure robust, high-performance actuation and sensing across complex multi-joint robotic systems operating in demanding industrial environments.

Responsibilities

Design, implement, and maintain EtherCAT master and slave drivers for distributed robotic systems

Develop real-time motor control software for multi-axis actuation systems

Integrate servo drives, motor controllers, encoders, IMUs, force/torque sensors, and other field devices

Implement deterministic communication pipelines with strict timing constraints

Optimize control loop performance (current, torque, velocity, and position loops)

Develop and debug CAN, SPI, UART, and other industrial communication protocols as needed

Collaborate with controls engineers to implement advanced control strategies

Build tooling for diagnostics, logging, and fault detection across the actuator network

Support hardware bring-up, system integration, and field debugging

Develop safety mechanisms and fault recovery systems for high-power robotic platforms

Contribute to PCB bring-up and embedded firmware validation when required

Document system architecture, timing constraints, and integration processes

Requirements

Bachelor’s or Master’s degree in Mechatronics, Electrical Engineering, Robotics, or related field

3+ years of experience in embedded systems or mechatronics engineering

Strong experience with EtherCAT (CiA 402, distributed clocks, PDO/SDO configuration)

Experience developing real-time systems (RT Linux, PREEMPT_RT, Xenomai, or similar)

Strong C/C++ programming skills for low-level system development

Experience with servo drives and motor control (FOC, BLDC, PMSM, etc.)

Understanding of control theory (PID, cascaded control loops, system identification)

Experience working with oscilloscopes, logic analyzers, and hardware debugging tools

Familiarity with industrial communication protocols (CAN, SPI, I2C, UART)

Understanding of power electronics fundamentals and actuator systems

Experience integrating multi-axis robotic systems

Nice to Have

Experience developing or modifying EtherCAT master stacks

Familiarity with SOEM, IgH EtherCAT Master, or commercial EtherCAT stacks

Experience with safety-rated motion systems

Background in humanoid robots or high-DOF robotic systems

Experience with FPGA-based motor control or real-time acceleration

Familiarity with ROS / ROS2 integration with real-time control layers

Experience designing custom motor controllers or embedded boards

Knowledge of EMI/EMC considerations in high-power robotic systems

Experience working in industrial environments (construction, mining, energy, manufacturing)

Understanding of functional safety standards

The base salary range for this full-time position is $120,000 - $250,000, in addition to bonus, equity and benefits.
