Fluid Design Engineer

The role is a specialist position responsible for evaluating rocket designs from a fluid-dynamics perspective and accelerating feedback to the design process. Day-to-day work includes conducting and assessing CFD analyses for rocket development.

The analyses cover external flows in supersonic and transonic regimes, as well as internal flows in the vehicle. Internal-flow work includes air conditioning, pressurization supply systems, cryogenic fluids, and rotating machinery.

The position evaluates the validity of CFD results and incorporates the findings into design decisions. This includes checking consistency with engineering theory, analytical solutions, and approximate formulas, and examining numerical errors, convergence, and non-physical phenomena.

The role also advances the CFD analysis platform by establishing policies for selecting solvers, turbulence models, and boundary conditions, and by developing mesh designs and quality standards. Collaboration with design departments and business partners is part of the work.

The Fundamental Technology Group establishes company-wide analysis technology foundations. Its stated mission includes ensuring the reliability of numerical analysis based on Verification & Validation, establishing evaluation metrics that support design decisions, and using CFD to understand phenomena and inform design judgments.

The work location is the Tokyo Second Branch in Koto-ku, Tokyo.
