Posting Details As a pioneer in robotics, satellite systems, and geospatial intelligence, with a 55-year history of world-firsts and more than 450 missions, MDA Space is a worldwide leader in communications satellites, Earth and space observation, as well as space infrastructure and exploration. The MDA Space team—more than 5,500 space experts in Canada, the United States, and the United Kingdom—has the knowledge and know-how to turn a client’s bold vision into an achievable mission, thanks to a unique blend of experience, technical excellence, and wonder that has been part of our DNA from day one. to join our satellite systems team at our Montreal office. As the world’s leading independent commercial supplier of antennas, payloads, and electronics for communications satellites and radars, our team has successfully contributed to hundreds of missions over the past 60 years. With deep experience delivering a wide range of solutions to customers worldwide, our satellite-systems group continues to grow and evolve both on the ground and in the stars. to spark fresh, innovative problem-solving approaches that help us improve life on and above Earth. As an equal-opportunity employer that values diversity, integrity, and collaboration, we are committed to strengthening MDA’s and Canada’s leadership status in this new chapter. In a multidisciplinary engineering team, the senior thermal architect plays a key role in the design, analysis, and validation of thermal control for satellites and satellite subsystems. The position involves leading thermal-optimization studies, overseeing the creation of thermal mathematical models (TMM), and supervising thermal testing to ensure reliable performance of space systems in the extreme thermal environments of space. Solve thermal challenges specific to electronic subsystems such as high-power processors and RF systems, and ensure effective integration of thermal solutions with mechanical and electrical designs.



Perform thermal-optimization analyses to maximize system performance, mass, and power consumption while meeting mission requirements. Evaluate thermal-control strategies, including active and passive systems (MLI surface finishes, thermal straps, radiators, heat pipes, etc.). Oversee the creation of high-fidelity thermal models to predict behavior in various operating scenarios, including test, launch, and on-orbit phases. Develop test plans and procedures to demonstrate the validity of thermal concepts and analyze test reports. Supervise thermal testing, including thermal-vacuum (TVAC) tests and ambient-pressure thermal-cycle tests. Act as the thermal authority within cross-functional teams, working closely with systems specialists and mechanical designers. Support the integration of thermal components with satellite assemblies. Propose and implement innovative solutions to thermal challenges to improve performance and reduce cost. Bachelor’s degree (minimum) in mechanical or aerospace engineering, or equivalent. At least 15 years of experience in space thermal engineering at the satellite and subsystem level, preferably in a commercial setting. Experience in thermal testing, including TVAC operations, thermal-cycle chambers, instrumentation, and data processing. Ability to communicate verbally and in writing in both French and English (customer contact outside Québec). Knowledge of electronic packaging. Experience in thermal testing. Experience in the space industry and understanding of electrical requirements are assets. Selected candidates must obtain and hold a security clearance at the reliability level and pass the security assessment for the Controlled Goods Program (CGP) and ITAR. As a member of the MDA team, you and your eligible dependents can enroll in a benefits program that provides comprehensive protection through competitive health care, including supplemental health plans and flexible drug-insurance plans, dental and vision coverage, disability income protection, life insurance, group retirement savings plans, and an employee-and-family assistance program.
