Embedded Software Engineer – Canada at Spaceium Inc

At Spaceium, we are building spacecraft systems designed to push the boundaries of what’s possible in orbit. As an Embedded Software Engineer, you will develop the core software that directly interfaces with spacecraft hardware. You will work on mission-critical embedded systems responsible for controlling hardware, managing data flows, and ensuring reliable operation in the harsh environment of space. This role involves designing, implementing, testing, and deploying highly reliable software on embedded platforms. This is an opportunity to be one of the first software engineers at the company, working directly with the CTO to shape the architecture and development practices for our spacecraft software stack. Responsibilities Design and develop embedded software for spacecraft avionics and control systems Write efficient and reliable firmware using C, C++, and Python Develop software for microcontrollers and embedded processors Interface software with sensors, actuators, and spacecraft subsystems Implement communication protocols such as RS422, I2C, SPI, CAN, and Ethernet Develop real-time systems for spacecraft control and operations Build tools for data acquisition, diagnostics,
