Turbomachinery Engineer - Fluidic Design

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 700 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

Canada Rocket Company is building the turbomachinery that drives our700kNengine. We’re looking for a Turbomachinery Engineer-Fluidic Design to lead the analysis, design, and optimization of the rotating machinery at the heart of the engine;pumps:inducers, impellers, diffusers, volutes;turbines:manifolds,nozzles and rotor blades;and the secondary flow systems/axial thrustbalancing.You’llown the hydrodynamic and aerodynamic design point, the off-designbehaviour,and the secondary circuitusing both reduced order modeling and 3DCFD.

What you’ll do

• Lead the fluidic design of cryogenic pumps and hot-side turbines end-to-end, inducers, impellers, diffusers, volutes, turbine manifolds, nozzles and rotors; the secondary flow circuits/axial balancing systems from preliminary sizing through detailed design and validation.
• Define and refine flow path geometry in Siemens NX and develop blade definitions in ANSYS BladeModeler.
• Run CFD analyses across the full envelope: steady and transient, single- and multiphase, cavitating inducer flow, supersonic blade rows, and rotor-stator interaction. Use ANSYS Workbench / Fluent / CFX on Linux/HPC.
• Own performance prediction across the operating map: NPSH margins, head-flow and efficiency curves, blockage and stall limits, tip leakage, secondary flow losses, supersonic nozzle while considering mechanical limitations.
• Investigate off-design and transient behaviour, start and shutdown transients, throttling, and cycle coupling, and feed the results back into the design and the engine cycle model.
• Develop and maintain in-house preliminary design codes, reduced-order models, and post‑processing tooling in Python, MATLAB, or FORTRAN. Build the workflow, not just the report.
• Drive pre-test predictions, instrumentation strategy, and post-test correlation for component and full turbopump campaigns. Reconcile CFD with measured data, close the loop, and improve predictive capability for the next build.
• Work directly with mechanical design, manufacturing, and test to make sure what’s analytically optimal is also buildable and inspectable. Push back on geometry that’s expensive or risky to produce.
• Produce the analysis reports, test reports, and design review packages that anchor configuration decisions across the program.

Qualifications

• Bachelor’s degree in mechanical engineering, Aerospace Engineering, or a closely related field, with a minimum of 5 years of relevant experience. A graduate degree with 3 years of experience is equivalent. PhD candidates are also welcome to apply.
• Strong foundation in aerodynamics, thermodynamics, hydrodynamics, and the principles of high‑speed turbomachinery, with the ability to lead the analysis, design, and optimization of inducers, impellers, diffusers and volutes as well as turbines nozzles and rotor blades in cryogenic and high-temperature environments.
• Deep working knowledge of cavitation and NPSH analysis, rotor‑stator interaction, secondary flow losses, and high‑temperature supersonic turbine.
• High proficiency with commercial CFD codes (ANSYS Workbench / Fluent / CFX), including steady, transient, cavitation, and multiphase modeling. Strong meshing discipline - structured/unstructured, boundary-layer resolution, y⁺ control, and grid convergence using TurboGrid, ICEM‑CFD and other Ansys meshing tools.
• Fluency with Siemens NX for flow path and assembly geometry, and with ANSYS BladeModeler (or equivalent) for blade definition. Comfortable owning the geometry from concept through CFD without dropping fidelity at the handoff.
• Solid programming and scripting ability in Python, MATLAB, or FORTRAN for preliminary design tools, reduced-order modelling, post-processing, and automation.
• Prior exposure to aerospace configuration control and traceability for flight or test hardware.
• Hands‑on experience correlating CFD and analytical predictions with test data - cold-flow, spin, or hot-fire - and using the correlation to drive design iterations.
• Familiarity with engine cycles (gas generator, staged combustion, expander, etc.), cryogenic propellants, and the reliability constraints of high-speed rotating equipment.
• Ability to produce clear analysis and test reports and to present results to internal teams and external customers.
• Fluent English, strong communication skills, and effectiveness in multidisciplinary engineering environments.
