Mechanical Engineer - Thermal Design
Dominion Dynamics, Ottawa HQ
The role
Reports to: Head of Hardware
Type: Full-Time
Our systems are built for continuous operation in harsh, remote, and mission-critical environments where reliability is non-negotiable. The difference between a lab prototype and a fielded capability is often heat. Sealed, rugged electronics must reject the power they dissipate across extreme temperature swings, often with limited or no forced airflow, for the life of the mission.
This role converts system requirements into thermal architectures and hardware that keep sensitive electronics within their limits and can be produced at scale and serviced in the field. You'll drive the thermal design, analysis, and validation of mission-critical electronics, from early concept and simulation through prototyping, test, and ramp to production with suppliers.
