Fluids Engineer We are looking for a Fluids Engineer to join our Structures team and help design, analyze, and test the fluid systems that manage our propellant feed systems.

You''ll work across the full lifecycle of propellant tanks and feed-system development from trade studies and first-principles modeling through hardware testing and flight qualification.

This is both an analytical and hands-on role for someone who wants to see their analysis translate directly into hardware on the test stand and, ultimately, on the launch pad.

At Nord

Space, you''ll play a meaningful role in developing technologies that make a difference in the rocket industry.

We believe in investing in early-career talent and providing opportunities to learn, innovate, and grow alongside industry experts.

If you''re excited about solving complex challenges, we''d love to hear from you Core responsibilities Design and analyze propellant feed systems, including propellant tanks, pressurization systems, valves, regulators, ducting, and manifolds for liquid rocket engines and vehicle-level fluid systems Perform fluid dynamics analysis (incompressible and compressible flow, single- and two-phase flow, cavitation, water hammer, and transient flow phenomena) using both analytical methods and CFD tools Size and select components such as valves, orifices, filters, regulators, and relief devices; generate flow schematics (P&IDs;) for engine and ground support systems Develop and maintain fluid system models (e.g., in Ecosim

Pro/ESPSS, Simulink, Flownex, or custom Python/MATLAB tools) to predict steady-state and transient system behavior Support propellant and pressurant selection trades,



tank pressurization schemes (autogenous, cold gas, etc.), and system-level mass/performance trades Work closely with Structures, Propulsion and Avionics engineers to ensure fluid systems integrate cleanly with propellant tanks, pressurization systems, and propellant manifolds Define instrumentation and test requirements for component- and system-level hot-fire and cold-flow testing; support test planning, execution, and post-test data analysis Root-cause anomalies observed in testing (e.g., cavitation, pogo, water hammer, chugging, flow instabilities) and propose design or operational fixes Generate and maintain technical documentation: analysis reports, design review packages, requirements, and verification/qualification plans Support hardware fabrication, assembly, and proof/leak/flow testing of fluid components Qualifications Bachelor''s degree in Mechanical, Aerospace, Chemical Engineering, or a related field (or equivalent practical experience) Solid grounding in fluid mechanics and thermodynamics, including compressible flow, two-phase flow, and transient (unsteady) flow analysis Experience with fluid system modeling or simulation tools Working knowledge of CFD (e.g., ANSYS Fluent, STAR-CCM+, OpenFOAM) for component-level flow analysis Familiarity with propellant and pressurant properties relevant to liquid rocket propulsion (e.g., LOX, RP-1, nitrogen) Comfortable working with cryogenic fluid systems and associated safety practices Solid analytical and problem-solving skills with the ability to work from first principles when tools or data are limited Experience reading and generating P&IDs;, schematics, and engineering drawings
