Catalyx Space is developing next-generation entry systems for space. As a Senior Design Engineer (Structures), you will lead the design, development, integration, and qualification of the primary structure for spacecraft and reentry vehicles. This role combines hands-on CAD/FEA expertise with system-level ownership, requiring experience across composites, pressure vessels, pyrotechnic devices, and full spacecraft qualification.

You will bring flight heritage experience to ensure Catalyx hardware is reliable and flight-ready.

Responsibilities:

- Be responsible for defining the product from scratch — from concept through flight readiness.

- Own the overall BOM, vehicle configuration, hardware release process, and PLM.

- Take ownership of the entire spacecraft qualification campaign and flight acceptance testing, ensuring hardware is validated at the system level, not just subsystems.

- Define the test campaign for spacecraft and reentry systems.

- Define volume, mass, CG, and stiffness boundaries for other departments.

- Own the SolidWorks CAD design of primary structures and assemblies.

- Perform FEA modelling and analysis using ANSYS, Abaqus, or equivalent tools.

- Define assembly sequences for spacecraft structures and subsystems to ensure productive integration and test flow.

- Oversee the full spacecraft integration process, from structural build-up through final system closeout.

- Collaborate with engineering teams to provide Design for Manufacturability (DFM)



feedback and propose creative solutions for complex part geometries.

- Apply design for additive manufacturing principles in complex designs.

- Define and derive torque requirements for fasteners and joints.

- Oversee MGSE hardware design for integration and test operations.

Qualifications

- Bachelor’s/Master’s in Mechanical or Aerospace Engineering, or related field.

- 5+ years of experience in spacecraft or reentry structural design.

- Flight heritage required direct experience delivering hardware that has flown.

- Expert proficiency in SolidWorks CAD.

- Strong expertise in tolerance stack-up analysis.

- Deep knowledge of FEA modelling (vibration).

- Proven experience with vibration testing.

- Extensive experience with composites, including sandwich panels and high-temperature materials.

- Experience designing and validating pressure vessels for space applications.

- Experience working with pyrotechnic devices and integrating them into structural systems.

- Expertise in 3D printing and additive manufacturing design.

- Experience with high-temperature fabrics, woven composites, or textile-based structures.

- Familiarity with textile engineering concepts (weaves, stitching, layups).

Preferred Skills

- Proven ability to deliver flight-ready structural hardware.

- Background in algorithmic or generative design methods for lightweight structures.

- Excellent communication skills, both written and verbal.

- Willingness to work extended hours and/or weekends as needed.
