About Catalyx Space

We’re building AWS for space—providing in-space experiments and tech demos across LEO, deep space, and lunar orbit. Our offerings include unmanned labs, testbeds for rideshare and dedicated missions, and re-entry capsules for payload return. We simplify access with end-to-end solutions, no minimum mass limits, zero integration fees, and fast deployment (≤6 months), serving biopharma, semiconductors, materials science, defense, and more.

Role

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 across composites, pressure vessels, pyrotechnic interfaces, and full qualification campaigns.

You will help ensure Catalyx hardware is reliable, manufacturable, and flight‑ready.

Key responsibilities

• Define the product from concept through flight readiness
• Own overall BOM, vehicle configuration, hardware release process, and PLM coordination
• Take ownership of spacecraft qualification campaigns and flight acceptance testing at the system level
• Define test campaigns for spacecraft and reentry systems
• Define volume, mass, CG, and stiffness boundaries for cross‑functional teams
• Own 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 support efficient integration and test flow
• Oversee spacecraft integration from structural build‑up through final closeout
• Collaborate with engineering teams to provide DFM feedback and practical design solutions for complex geometries
• Apply additive‑manufacturing design principles where appropriate
• Define and derive torque requirements for fasteners and joints
• Oversee MGSE hardware design supporting integration and test operations

Qualifications

• Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, or a related field
• 5+ years of experience in spacecraft or reentry structural design
• Direct experience delivering space hardware through qualification and flight readiness
• Expert proficiency in SolidWorks CAD
• Strong expertise in tolerance stack‑up analysis
• Deep knowledge of FEA modelling for structural and vibration analysis
• Proven experience with vibration testing
• Extensive experience with composites, sandwich panels, and high‑temperature materials
• Experience designing and validating pressure vessels for space applications
• Experience integrating pyrotechnic devices into structural systems
• Experience with high‑temperature fabrics, woven composites, or textile‑based structures
• Familiarity with textile engineering concepts such as weaves, stitching, and layups

Nice to have

• Proven ability to deliver flight‑ready structural hardware
• Background in algorithmic or generative design methods for lightweight structures
• Strong written and verbal communication skills
• Flexibility to support extended hours or weekend work during critical integration or test phases
• Competitive salary (details will be shared with shortlisted candidates)
• Health insurance
• Provident fund.
