Senior Electrical Engineer (Canada)

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 Senior Electrical Engineer to join Xona’s spacecraft hardware development team in Montréal. In this role, you will support the design, development, and testing of electrical systems that enable spacecraft subsystems, such as reaction wheels, SADAs, and torque rods. You will work closely with mechanical, systems, and other avionics 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 - Support the design and development of electrical subsystems for spacecraft system hardware (e.g., motor control electronics and sensor interfaces). - Contribute to schematic capture and PCB layout for control electronics and support circuits. - Assist with selection, architecture, and development of firmware and software for both flight and ground systems. - Assist with development and execution of electrical test plans for breadboard, engineering model, and flight hardware. - Troubleshoot and debug electronics in the lab using standard test equipment (oscilloscopes, logic analyzers, power supplies, etc.). - Support integration of hardware with spacecraft avionics and power systems. - Contribute to electrical interface control documentation (ICDs) and subsystem documentation. - Assist with hardware bring-up, verification testing, and environmental test campaigns. - Support supplier component evaluation and selection for electrical and electromechanical components. Required Qualifications - B.S. in Electrical Engineering or a related field. - 3-5+ years 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, KiCad, or similar. - Solid fundamentals in electronics, 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 in firmware and software development and debugging. - Exposure to spacecraft systems, ADCS hardware, or electromechanical control systems. - Experience with control or power electronics. - Familiarity with embedded systems and communication interfaces (SPI, I2C, CAN, etc.). - Experience supporting hardware integration, assembly, or environmental testing. - Interest in spacecraft hardware development and space systems engineering. Xona est une entreprise spécialisée en intelligence de navigation, offrant une précision en temps réel au centimètre près à tout appareil, partout sur Terre.
