About Canada Rocket Company

Canada Rocket Company is developing Canada's first medium-lift launch vehicle.

We are a team of veterans from SpaceX, Blue Origin, Rocket Lab, ArianeGroup, Pangea Propulsion, Tesla, MDA, and more, bringing over a century of combined launch and space systems experience back to Canada.

Our mission is to provide reliable, independent access to space for Canada and its allies in a rapidly expanding global market.

Our approach is defined by pragmatic engineering:

• We utilize a single 725 kN engine that scales from light- to medium-lift via engine clustering
• We lean on simple, proven technologies to reach orbit faster, avoiding the pitfalls of complex or novel designs
• We test early and often, catching problems on the bench instead of at the pad

Backed by over $20M in funding secured within our first four months, including the largest all-Canadian seed round in the sector and an $8.3M Department of National Defence grant, we are moving with the speed and institutional backing required to meet Canada’s orbital launch needs.

About the Role

We are looking for a Propulsion Engineer to own the design, development, and qualification of the hardware that makes up our combustion system — injectors, thrust chambers, nozzles. This role is focused on deep, hands-on component ownership: taking a component from requirements and first-principles design through detailed engineering, analysis, test, and flight qualification.

You will work primarily within the propulsion team, partnering with fluid systems, structures, manufacturing, and test to develop hardware that performs reliably under extreme pressure, temperature, and vibration environments. This is a highly technical role for an engineer who wants to deep dive into component-level design, analysis, manufacturing and testing. This is a role for someone who wants to solve hard, physics-driven design problems and own components end to end.

What You Will Do

• Own the design and development of combustion system components – injectors, thrust chambers, nozzles
• Be accountable for component-level design from concept through detailed design, manufacturing, component test, and flight qualification
• Translate propulsion system requirements into component-level design concepts, detailed designs, and released hardware that meets functional, structural, thermal, and reliability targets
• Develop CAD models, detailed drawings, and release packages for components spanning prototype, development, qualification, and flight configurations
• Drive design-for-manufacture and design-for-assembly decisions specific to propulsion components, working closely with the manufacturing team on machining, brazing, welding, and additive processes
• Support component-level test planning, instrumentation, and post-test analysis to validate design assumptions and drive design iteration

Qualifications

Required

• 5+ years of experience in mechanical design and development of propulsion or other aerospace hardware that are used in high-temperature environments
• Ownership of combustion system components from concept through detailed design, manufacturing, test, and qualification
• Proficiency in CAD, GD&T, and mechanical drawing creation, with the ability to generate clear, manufacturable, and well-controlled hardware definitions for precision components
• Experience designing hardware for high-pressure, high-temperature, or cryogenic service
• Strong understanding of manufacturing processes relevant to propulsion hardware (machining, brazing, welding, additive manufacturing) and how design decisions affect producibility, cost, and quality
• Experience working with suppliers to source COTS components and manufacture in-house designed parts
• Ability to operate with ownership in a fast-paced, cross-functional hardware development environment
• Excellent communication and collaboration skills
• Bachelor's degree in mechanical engineering, aerospace engineering, or a related field

Preferred

• Direct experience designing liquid or hybrid rocket propulsion components
• Ability to perform and interpret engineering analyses using a combination of first-principles calculations and FEA/CFD tools, with sound judgment on the level of analysis appropriate to the component
• Hands-on experience with hot-fire or component-level propulsion testing, including instrumentation and post-test data analysis
• Understanding of combustion dynamics and how it influences hardware design
• Familiarity with rapid design-build-test hardware development environments
• Advanced degree in mechanical engineering, aerospace engineering, or a related field
