Position Introduction/Key Duties

Cimarron is seeking an experienced Propulsion Staff Engineer – Thruster Systems to own the end-to-end technical execution of a bipropellant thruster from requirements definition through design, build, integration, test, and flight readiness. You will lead cross-functional teams and suppliers to deliver to aggressive cost and schedule targets while maintaining safety and configuration discipline. The ideal candidate combines deep hands‑on propulsion hardware experience with strong technical leadership, clear communication, and a bias for execution.

This is an onsite position located in Houston, TX.

Key Duties:

Ownthe end-to-end technical execution of bipropellant thruster assemblies including combustion chambers, injectors, nozzles, igniters, and associated valves/instrumentation – from requirements through, design, build, integration, test and flight readiness.
Serve as a subject matter expert in thruster design, providing technical authority on system architecture, sizing, fluid/thermal/structural analyses, materials/manufacturability, and performance optimization across the full development lifecycle.
Perform detailed modeling, analysis and simulation of thruster assemblies using tools such as ANSYS, Fluent, TDK, CEA, etc to evaluate combustion performance, thermal effects, structural margins and transient behaviors.
Perform component sizing and selection for thruster assemblies, ensuring compatibility with performance, thermal, structural, safety and compatibility requirements.
Design, plan and execute thruster development, qualification, and acceptance test campaigns define instrumentation requirements, execute test planning and perform data correlation to anchor and validate analytical models.
Lead and participate in internal and external design and gate reviews, trade studies, and subassembly integration activities; ensure compliance with system requirements and program milestones.
Coordinate and manage technical requirements and design verification activities with external vendors and suppliers, interface on cost, schedule, design, manufacturing, and acceptance.
