Catalyx Space is developing next-generation entry systems for space. As a Space Mechanisms Engineer - Deployable Structures at Catalyx, you will focus on the design, development, and testing of deployable structures for spacecraft and entry system applications. You will also be responsible for developing Hold-Down and Release Mechanisms to ensure reliable deployment in space.

Responsibilities:

• Design and develop deployable structures and associated mechanisms.
• Develop and qualify HDRMs for spacecraft subsystems.
• Support mechanism testing campaigns including vibration, TVAC, and deployment tests.
• Collaborate with avionics and systems teams for actuator and sensor integration.
• Deliver tested, flight-ready deployable hardware.

Qualifications:

• Bachelor’s in Aerospace/Mechanical Engineering or related field.
• 2–5 years of experience in spacecraft deployable structures and mechanisms.
• Hands-on experience with mechanism design, hinges, latches, and HDRMs.
• Strong expertise in GD&T (ASME Y14.5 standards), DFM, and design for additive manufacturing (DfAM).
• Experience with SolidWorks layout design, linkage, or equivalent mechanism design software.
• Strong understanding of tolerance stack-up analysis.
• Experience in modeling complex joints in deployable or flexible structures.
• Proven experience with vibration testing and analysis of mechanisms.
• Expertise in creating CMM probing area descriptions of parts for inspection and validation.
• Deep experience with coatings, plating, and other surface treatment processes.
• Strong experience with ANSYS or similar CAE packages for structural, modal, and thermal analysis.
• Exposure to testing and validation of deployable structures.

Preferred Skills:

• Familiarity with complex spacecraft deployable structures.
• Proven ability to deliver flight heritage hardware.
• Background in algorithmic or generative design for mechanisms.
• Demonstrated ability to work in a fast-paced, test-driven environment.
• Excellent communication skills, both written and verbal.
• Willingness to work extended hours and/or weekends as needed.

About Us:

We're building AWS for space, providing space experiments and technology demonstrations across LEO, deep space, and lunar orbit.

Our offerings include unmanned labs, testbeds for both dedicated and rideshare missions, and re-entry capsules for payload retrieval.

We simplify access to space with affordable pricing, end-to-end solutions, no minimum mass limits, zero integration fees, and quick deployment (6 months or less).

We serve biopharma, semiconductors, materials science, defense, and more.
