Catalyx Space is building next-generation entry systems and spacecraft platforms. As a Senior Space Mechanisms Level -III, you will lead the design, development, and qualification of spacecraft separation devices. This role is suited for an engineer who has hands-on experience with flight-proven separation systems and is ready to own the full lifecycle of these critical mechanisms. Responsibilities: • Own the design, architecture, and qualification of spacecraft separation systems. • Lead development of separation mechanisms for spacecraft. • Support dynamic modelling and modal response simulations. • Conduct qualification testing: vibration, shock, and thermal vacuum. • Collaborate with systems and structures teams to ensure seamless integration. • Deliver flight-qualified separation hardware and supporting documentation. Qualifications: • Bachelor’s/Master’s in Aerospace/Mechanical Engineering or related field. • 5–10 years of experience in spacecraft mechanisms, with a minimum of 3 years dedicated to separation systems. • Direct hands-on experience with flight-proven spacecraft separation hardware. • Strong expertise in GD&T (ASME Y14.5 standards), DFM, and design for additive manufacturing (DfAM). • Strong understanding of tolerance stack-up analysis. • Experience with SolidWorks layout design, linkage, or equivalent mechanism design software. • Experience in modelling complex joints. • Proven experience with vibration analysis and testing of spacecraft mechanisms. • Expertise in creating CMM probing area descriptions of parts for inspection and validation. • Deep experience with coatings, plating, and other surface treatment processes for mechanism hardware. • Strong experience with ANSYS or similar CAE packages for structural, modal, and thermal analysis of mechanisms. • Experience with qualification test campaigns (shock, vibration, TVAC). • Responsible for procurement activities and coordinating with vendors to ensure timely delivery of parts and services Preferred Skills: • Familiarity with spacecraft separation systems. • Proven ability to deliver flight heritage hardware. • Excellent communication skills, both written and verbal. • Willingness to work extended hours and/or weekends as needed.
