You will build high-fidelity models of thruster systems — from propellant feed lines through combustion and nozzle expansion — and work hand-in-hand with thruster designers to optimize hardware before it's ever built. Your expertise in engine balance modeling, injector design and sizing, and combustion stability will directly determine the performance and reliability of the next generation of in-space propulsion systems. This is a rare opportunity to do foundational analytical work on hardware that will operate in the most unforgiving environment imaginable.  RESPONSIBILITIES <ul> <li>Own engine balance and cycle modeling: Develop and maintain integrated 1D engine/thruster cycle models in ROCETS, Sinda/Fluint, or equivalent tools to predict system-level performance, identify design sensitivities, and support architecture trade studies from concept through flight. </li> <li>Lead injector analysis and sizing: Apply first-principles and empirical methods to size injector elements, predict atomization and mixing efficiency, and validate designs against performance targets. Translate model outputs into actionable design guidance for hardware engineers. </li> <li>Assess and mitigate combustion instability: Perform stability assessments using analytical and numerical methods — including acoustic mode analysis, Rayleigh criterion evaluation, and sensitivity studies — and recommend design mitigations such as acoustic cavities, baffle configurations,
