[Nyx Earth] Propulsion CFD Engineer

Here at The Exploration Company, we are building spacecrafts for humanity.

As a talented Propulsion CFD Engineer, you will be responsible for the computational fluid dynamics analysis of propulsion system components and thruster plumes, providing the flow physics insight that underpins component design, thruster performance, and vehicle-level integration decisions.

Role Overview

CFD Analysis & Component Simulation

• Perform CFD simulations of propulsion components — valves, regulators, orifices, injectors, feed lines — to characterize internal flow, pressure drop, and flow-induced loads.

• Support design trade studies by predicting component-level performance across the operating envelope, in both steady-state and transient conditions.

• Identify and help resolve flow anomalies such as cavitation, choking, or flow separation that affect component performance.
  

Plume Characterization & Thruster Performance

• Model thruster plume characterization, from near-field continuum expansion through far-field rarefied flow, including relevant gas dynamics effects.

• Assess plume-induce
