About the Role
Canada Rocket Company is seeking a Turbomachinery Engineer - Fluidic Design to lead the analysis, design, and optimization of rotating machinery for their 700 kN engine. This role involves owning the hydrodynamic and aerodynamic design, off-design behavior, and secondary flow systems using reduced-order modeling and 3D CFD.
Responsibilities
- Lead the fluidic design of cryogenic pumps and hot-side turbines, including inducers, impellers, diffusers, volutes, turbine manifolds, nozzles, rotors, and 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, including steady and transient, single- and multiphase, cavitating inducer flow, supersonic blade rows, and rotor-stator interaction using ANSYS Workbench/Fluent/CFX on Linux/HPC.
- Own performance prediction across the operating map, including NPSH margins, head-flow and efficiency curves, blockage and stall limits, tip leakage, secondary flow losses, and supersonic nozzle, while considering mechanical limitations.
- Investigate off-design and transient behavior, start and shutdown transients, throttling, and cycle coupling, feeding results back into the design and engine cycle model.
- Develop and maintain in-house preliminary design codes, reduced-order models, and post-processing tooling in Python, MATLAB, or FORTRAN.
- Drive pre-test predictions, instrumentation strategy, and post-test correlation for component and full turbopump campaigns, reconciling CFD with measured data to improve predictive capability.
- Collaborate with mechanical design, manufacturing, and test teams to ensure analytical designs are buildable and inspectable.
- Produce analysis reports, test reports, and design review packages to anchor configuration decisions.
Requirements
- Bachelor's degree in mechanical engineering, Aerospace Engineering, or a closely related field, with a minimum of 5 years of relevant experience, or a graduate degree with 3 years of experience.
- Strong foundation in aerodynamics, thermodynamics, hydrodynamics, and the principles of high-speed turbomachinery.
- Ability to lead the analysis, design, and optimization of inducers, impellers, diffusers, volutes, turbine nozzles, and rotors in cryogenic and high-temperature environments.
- Deep working knowledge of cavitation and NPSH analysis, rotor-stator interaction, secondary flow losses, and high-temperature supersonic turbines.
- 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, 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 geometry from concept through CFD without dropping fidelity at handoff.
- Solid programming and scripting ability in Python, MATLAB, or FORTRAN for preliminary design tools, reduced-order modeling, 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 correlation to drive design iterations.
- Familiarity with engine cycles (gas generator, staged combustion, expander, etc.), cryogenic propellants, and reliability constraints of high-speed rotating equipment.
- Ability to produce clear analysis and test reports and present results to internal teams and external customers.
- Fluent English and strong communication skills.
- Effectiveness in multidisciplinary engineering environments.
