Building the space between proven and possible, MDA Space is a trusted mission partner to the global space industry. A robotics, satellite systems and geointelligence pioneer with a 55-year+ story of world firsts and more than 450 missions, MDA Space is a global leader in communications satellites, Earth and space observation, and space exploration and infrastructure. The global MDA Space team of more than 3,800 space experts has the knowledge and know-how to turn an audacious customer vision into an achievable mission – bringing to bear a one-of-a-kind mix of experience, engineering excellence and wide-eyed wonder that’s been in our DNA since day one.MDA is looking for a Satellite Bus System Engineer (Grade32) to support the definition, design, integration, verification and on‑orbit activities of the platform subsystems (structure, thermal, power‑distribution, attitude‑control, propulsion, C&DH;, TT&C;/PDT, flight‑software and payload interfaces) for current and next‑generation remote‑sensing and communications satellites.

The engineer works under the direction of senior system engineers and contributes technical expertise while gaining exposure to the full spacecraft‑bus life‑cycle. Contribute to the Platform Architecture Description Document, Interface Control Documents (ICDs) and Design Description drafts.Perform requirement entry and help maintain bidirectional traceability throughout the program life‑cycle using MDA’s requirement‑management tools.
