About Catalyx Space:

Catalyx Space is building the world's best reentry systems. Our reusable ReX vehicles return payloads from orbit at unprecedented scale, up to 12 tons and 60m³ of cargo, while operating the full mission lifecycle from launch to recovery. Our core innovation is a Origami-inspired deployable heat shield that combines the scalability of an inflatable system with the robustness of a rigid structure. Built from commercial off-the-shelf components, it enables the world's widest heat shields, the largest payload return volumes, and a scalable pathway for returning everything from commercial cargo to future space nuclear assets.

Role:

As a Propulsion Engineer at Catalyx Space, you will be responsible for engine development and propulsion plumbing for our entry-system propulsion module. You will design, build, and test thrusters and fluid systems, working hands-on from concept to test bench.

You will collaborate closely with the senior propulsion engineer to help deliver a flight-ready propulsion system.

Key responsibilities:

• Own propulsion hardware development, including design, prototyping, and hot-fire testing
• Develop and implement plumbing layouts for feed systems and system integration
• Design and develop DAQ and safety systems for propulsion testing
• Support valve, tank, and line integration
• Troubleshoot, iterate, and deliver tested propulsion hardware ready for system integration
• Design and develop static-fire stands and related test infrastructure for propulsion validation

Qualifications:

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or a related field
• Around 3 years of experience in propulsion, fluid systems, or thermal systems
• Hands-on experience with thruster or engine testing and plumbing layouts
• Strong expertise in SolidWorks for CAD modelling and assemblies
• Working knowledge of GD&T, DFM, and design for additive manufacturing
• Ability to perform material selection and support hardware trade-offs
• Familiarity with NASA CEA or equivalent propulsion analysis tools
• Strong problem-solving ability in lab and test environments

Nice to have:

• Direct experience contributing to flight-ready or flight-qualified propulsion hardware
• Exposure to earth-storable, non-toxic bipropellant engines
• Familiarity with propulsion instrumentation and DAQ systems
• Experience with engine testing workflows and plumbing optimization
• Exposure to algorithmic engineering design
• Strong written and verbal communication skills
• Flexibility to support extended hours or weekend work during critical build or test phases

Compensation & benefits:

• Competitive salary (details will be shared with shortlisted candidates),
• health insurance
• Provident fund.
