Sr. Mechatronics Designer/specialist

Sr. Mechatronics Designer

Xona is the navigational intelligence company bringing real-time, centimeter-level certainty to any device, anywhere on Earth.

With Pulsar – the world's most advanced PNT satellite infrastructure in Low Earth Orbit – Xona will offer a future-proof, backwards-compatible global positioning system optimized for absolute precision, superior power, and robust protection.

We are seeking a Sr. Mechatronics Designer to join Xona's spacecraft hardware development team in Montréal, at the historic RCA Victor Building in St. Henri. In this role, you will support the design, development, and testing of electro-mechanical systems such as those that enable spacecraft attitude determination and control and improve power performance.

You will work closely with mechanical, electrical, systems, avionics, and software engineers to help develop high-reliability electromechanical hardware for satellite flight systems. This is a hands-on role involving both electrical design and laboratory testing, with opportunities to contribute throughout the development lifecycle from early prototyping, through spacecraft integration and test and into full scale manufacturing.

What You'll Do

• Own subsystem design authority for assigned hardware, including requirements decomposition from spacecraft-level specs.
• Support the design and development of electro-mechanical subsystems for spacecraft system hardware, with a focus on dynamic mechanical systems and electrodynamic systems (i.e. stator design and modelling).
• Collaborate with mechanical engineers on integrated rotor/bearing/housing designs, ensuring electrical and mechanical interfaces are co-optimized.
• Assist with electrical design, sensor interface circuits, and power conditioning.
• Assist with development and execution of test plans for breadboard, engineering model, and flight hardware.
• Troubleshoot and debug electro-mechanical assemblies in the lab and develop a detailed test plan for execution.
• Support integration of hardware with spacecraft avionics and power systems.
• Support Design for Manufacturability (DFM) efforts as subsystems transition from prototype to sustained production, including fixture development.
• Assist with hardware bring-up, verification testing, and environmental test campaigns.
• Support supplier component evaluation and selection for electrical and electromechanical components.

Required Qualifications

• Bachelor's Degree in Mechatronics, Mechanical, Electrical Engineering or a related field.
• Experience in leading electrical hardware design and development from concept to MVP and beyond.
• Familiarity with schematic capture and PCB design tools such as Altium, and mechanical CAD (such as solidworks) for electromechanical integration.
• Demonstrated experience designing motor drives, sensor electronics, or systems for precision mechanisms and robotics.
• Strong understanding of kinematics and dynamics, including the ability to specify, model, design, and test to those bound.
• Solid fundamentals power systems, and motor control principles.
• Hands-on experience with electrical testing and debugging using laboratory equipment.
• Strong problem-solving ability and attention to detail.
• Ability to work collaboratively within multidisciplinary engineering teams.

Desired Qualifications

• Experience with precision robotics.
• Experience with electric motors and high-speed rotary assemblies.
• Experience in electromagnetic compatibility and susceptibility testing and mitigation through design.
• Exposure to spacecraft systems, ADCS hardware, or electromechanical control systems.
• Experience with control or power electronics.
• Experience supporting hardware integration, assembly, or environmental testing.
• Understanding of control systems and application of control theory.
