MDA Space (TSX: MDA) is a trusted mission partner for the global space industry that creates the space between what is proven and what is possible. 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. For those who dream big and push the limits on Earth and among the stars to make the world a better place, we’ll take you there.

We are looking for a Principal Thermal Architect 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.

We are a dream team of passionate, collaborative, and determined people, and we are constantly looking for more individuals to join the #MDATeam to spark fresh, innovative problem-solving approaches that help us improve life on and above Earth. If you’re excited about expanding our footprint in space and want to inspire the next generation, we’ll lead you there.





We have entered a current era of exploration and development, and MDA invites anyone who wants to get involved and be part of it. 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.

Role

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.

The candidate must have deep knowledge of heat-transfer principles, extensive experience in satellite thermal management, strong analytical skills, an in-depth understanding of multidisciplinary interactions among subsystems, and a proven ability to innovate by introducing new technologies to solve complex challenges. Strong leadership and communication abilities are also required.

Responsibilities

- Lead thermal design at the satellite- and subsystem-level.
- 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.
- Document thermal concepts and present them during formal reviews.
- 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.
- Stay current on industry advances and leverage them to design and deliver innovative, cost-effective solutions.

Minimum Qualifications

- 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 environment.
- Knowledge of thermal design standards (ECSS, NASA, MIL-STD).
- Experience with thermal modeling, preferably using Siemens NX Space Systems Thermal.
- Experience in thermal testing, including TVAC operations, thermal-cycle chambers
