About this position
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 straightforward, 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 Fluids Analyst who is equally proficient in performing first order calculations as they are in running CFD or developing their own analysis code. You will work across design, analysis, development, operation, and reuse scenarios in a fast-moving development environment. This is a highly technical role for someone who wants to be close to details, make consequential design decisions, and help establish the propulsion and stage fluids systems of an orbital launch vehicle program from the ground up.

What You Will Do

Aerothermal design of propulsion components including Injectors, Thrust Chambers, Nozzles, Valves, and other fluid system parts

Analyze fluid transients, water hammer, priming, two-phase flow, cavitation, flow-induced loads,



and feed system coupling across engine and stage fluid systems

Perform thermal-fluid analysis of cryogenic propellants including chill-down, boil-off, and thermal conditioning

Run trade studies on system architecture and operating points to inform design decisions

Develop and validate pressurization system models (autogenous, helium, or self-pressurizing) to size pressurant requirements and predict ullage behavior

Build, run, and maintain system-level models in tools such as EcosimPro, ESPSS, Flownex, Fluent, CFX, or in-house Python/MATLAB codes

Support cold flow, hot fire, stage test, and flight campaigns with pre-test predictions and post-test data reconciliation

Support anomaly investigations and root-cause analysis for fluid-related issues

Qualifications

Required

7+ years of experience with one or more of the following:

Creating and running 1-D flow networks for component sizing

Performing 3-D fluid analysis on propulsion components

Analysis of cryogenic fluids

Combustion analysis including liquid injection modelling

Inclination toward a fast-paced, resource-constrained environment with rapid hardware development using iterative design-build-test cycles that are central to the engineering culture

Bachelor’s degree in mechanical engineering, aerospace engineering, or a related field

Preferred

Sub/trans/super/hypersonic aerodynamics of vehicle during ascent and re-entry

Thermal analysis proficiency

Structural analysis proficiency

Turbomachinery fluid analysis proficiency

Functional proficiency in CAD (NX) and Python

Experience with the following:

Performing Conjugate Heat Transfer analysis using Fluent or similar CFD tools on rocket engine components

Aerothermal design of bipropellant rocket engines

Exposure to complex fluid systems as well as understanding the behaviour of the mechanisms in those systems

Advanced degree in mechanical engineering, aerospace engineering, or a related field
