Role: Systems Engineer Location: Full-time
Space Technology

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.

As a Systems Engineer , you will own the definition, integration, and validation of spacecraft and reentry systems across engineering domains. You will contribute to system-level analyses, integration trade-offs, requirements management, CONOPS development, and operational readiness from design through flight.

Define system-level mechanical, thermal, electrical, and fluid interfaces
Perform system-level analyses to validate architecture choices against mission requirements
Define and maintain CONOPS (Concept of Operations) aligned with mission objectives and operational constraints
Establish and maintain system-level timelines with visibility into technical risks and bottlenecks
Drive configuration management and PLM discipline across teams




Interface with regulatory partners such as DGCA, FAA, or equivalent bodies for system compliance
Collaborate with operations and GNC/Flight Dynamics teams to ensure vehicle performance meets mission design
Bachelor's or Master's degree in Aerospace, Mechanical, Systems Engineering, or a related field

- 5+ years of experience in spacecraft systems engineering or multidisciplinary aerospace programs
- Experience supporting space missions across concept design, integration, testing, and/or operations
- Hands-on experience in requirements flow-down, interface control, trade studies, and system-level analysis
- Familiarity with system integration testing including vibration, TVAC, propulsion, and aero/thermal testing
- Proficiency with tools such as STK, MATLAB, Python, or system modelling frameworks
- Experience conducting or contributing to FMECA analyses

Prior experience on spacecraft or reentry systems that have flown
Solid technical problem-solving ability across multiple engineering domains
Experience with configuration management tools and PLM systems
Familiarity with safety and regulatory compliance in aerospace programs
Flexibility to support extended hours or weekend work during critical integration or test phases
