Job summary

Dominion Dynamics in Ottawa (with consideration for Montreal and Toronto) seeks a propulsion systems engineer to own engine selection, model performance across the flight envelope, and integrate the powerplant into the airframe from design through production, flight test, and field support.

The role requires hands-on airframe integration, interface documentation, and collaboration across structures, aero, and production teams to resolve real hardware issues in a fast-paced environment.

Qualifications

• Propulsion engineering experience across full lifecycle (engine selection through integration, test, and in-service support).
• Strong engine cycle analysis and performance modeling, including installation effects across the flight envelope.
• Hands-on airframe integration experience: nacelle, mounts, inlet/exhaust, and interfaces.

Responsibilities

• Run engine selection and trade studies evaluating platforms against mission profiles, thrust, SFC, emissions, acoustics, and lifecycle cost.
• Model engine performance across takeoff, climb, cruise, descent, and transient conditions including installation losses.
• Lead airframe integration of powerplant assembly and manage interfaces with structures and aero teams.
• Author and maintain ICDs for engine-airframe interfaces and optimize subsystem interfaces (fuel, thermal, electrical, avionics).
• Support production and flight test through installation, NCR/ECR disposition, and flight test planning.
