About The Position

As the Thermofluids Engineer II, you will be responsible for driving fluid system design for thermal management on the spacecraft through analysis, test, and validation. This role supports development and characterization of thermomechanical and fluid systems for payload, vehicle, and propulsion applications. You will be responsible for defining performance metrics, operational requirements, and hardware requirements for ground testing and flight. Day-to-day responsibilities include sizing thermofluid and system and component performance via hand calculations, simulation, and testing. Familiarity with typical thermomechanical hardware (valves, pumps, accumulators, heat exchangers, etc.), 0D and 1D fluid networks, and fluid system modeling is essential. Successful candidates thrive on solving hard problems, adapting to dynamic requirements, and collaborating across multiple domains. You will gain significant ownership, see your contributions rapidly come to life.

Requirements

B.S. in Mechanical Engineering, or a related discipline, with consideration given to equivalent professional experience (typically 1–3+ years)
1+ years experience in thermofluids and/or propulsion systems in a manufacturing environment
Strong heat transfer and incompressible fluid mechanics first principles
Background in 0D and 1D thermal and/or fluid networks
Expertise in one or more fluid or thermal modeling tools (SINDA/FLUINT, ANSYS, GFSSP, etc.)
Knowledge with thermomechanical systems: heat exchangers, cold plates, vacuum chambers, pumps, valves, RTDs, transducers, etc.
Hands-on experience in thermal and TVAC testing
Experience in MATLAB (or equivalent) for data processing and task automation
Excellent written and verbal communication skills with an aptitude for interdisciplinary technical communication
