Mission

As a Turbomachinery CFD Engineer, you will be responsible for designing and analysing components of the propulsion system related to turbomachinery, including turbine, pumps, bearings and sealing components. Your mission will involve developing and optimize high-performance turbomachinery designs to support our innovative microlauncher space vehicles.

Responsibilities

Design, build, and test turbopump hardware for MIURA 5 and MIURA NEXT first/second stage liquid propellant rocket engines.
Perform the aero/hydro sizing, flow path design, analysis work for the turbopumps using ANSYS CFX.
Generate and optimize geometry tools to iterate against CFD results to find the best pump and turbine engineering solution and blade parameters.
Work closely with the propulsion team to assure functional integration of the turbomachinery components in the engine system.
Provide feedback to identify, improve performance, increase reliability or manufacturability, and assembly at design level and operational level.

Necessary Requirements

Bachelor's or Master's degree in Aerospace, Mechanical Engineering, or related field.
5+ years of experience applying CFD to turbomachinery design and analysis (ANSYS CFX preferred).
At least 2-5 years of hands-on experience in fluid dynamic analysis of liquid rocket engine turbopumps, with focus on centrifugal pumps and associated turbomachinery components.
Strong understanding of fluid dynamics, thermodynamics, turbomachinery aerodynamics, and numerical simulation methods.
Demonstrated experience in one or more of the following areas:
Cavitation analysis and cavitation margin assessment.
Axial thrust prediction and thrust balancing systems.
Hydraulic design and optimization of centrifugal pumps and inducers.
Blade design and optimization for pumps and impulse turbines.
Fluid dynamic analysis of turbomachinery primary and secondary flow paths.
Combustion analysis of fuel-rich or oxygen-rich combustion devices such as gas generators and preburners.
Test data post-processing, model validation, and CFD-to-test correlation.
Rocket engine turbopump performance assessment and troubleshooting.

Desired Requirements

Experience defining, planning, and executing turbopump, gas generator, preburner, and integrated rocket engine development and qualification test campaigns.
Experience with rocket engine test operations, instrumentation selection, data acquisition systems, and test result interpretation.
Expertise in post-processing, reduction, validation, and correlation of turbomachinery and engine test data against analytical and CFD models.
Experience performing CFD analysis of combustion devices, including fuel-rich gas generators, preburners, injectors, manifolds, cooling passages, and combustion chambers.
Experience in injector design and fluid dynamic characterization, including atomization, mixing, pressure drop, and combustion stability considerations.
Knowledge of multiphase flow modeling, cavitation prediction, thermal‑fluid analysis, and cryogenic fluid behavior.
Familiarity with bearing system design, seals, balance pistons, and axial thrust balancing systems for rocket turbopumps.
Experience performing multidisciplinary optimization involving hydraulic, thermal, structural, and rotordynamic constraints.
Experience supporting failure investigations, root‑cause analysis, anomaly resolution, and engine troubleshooting activities.
Familiar with manufacturing capabilities (typical tolerances) and processes: turning, milling, drilling, reaming, EDM, grinding, brazing, welding, 3D printing. Familiar with mechanical seals.
