At Orbital Paradigm, we design, develop, manufacture, and operate reusable orbital logistics systems. Our spacecraft perform multiple orbital mission profiles and return safely to Earth through hypersonic atmospheric reentry and landing with pinpoint accuracy for rapid refurbishment and reuse.

Role Description
We are looking for a Mechanical Design Engineer to join our mechanical engineering team. The role covers the full hardware development lifecycle, from concept and detailed design through manufacturing, assembly, integration, and testing.

The position requires strong practical engineering capability in mechanical design, CAD modelling, manufacturing processes, tolerancing, technical drawings, fabrication methods, and mechanical interfaces. The engineer will work closely with suppliers, manufacturing partners, and multidisciplinary teams to deliver flight-ready hardware.

This is a hands-on role involving direct participation in fabrication, assembly, integration, troubleshooting, and test activities.

Key Responsibilities
Develop 3D CAD models, assemblies,



and manufacturing drawings
Design mechanical systems, structures, mechanisms, and interfaces
Perform tolerance analysis and apply GD&T; principles
Select materials, fastening methods, and manufacturing approaches
Ensure designs meet functional, manufacturability, and integration requirements
Prepare and maintain engineering documentation, BOMs, and CAD models
Interface with suppliers, machine shops, and manufacturing partners
Participate directly in hardware fabrication, machining, assembly, and integration activities
Support spacecraft and subsystem integration campaigns, including hands-on assembly and fit-check activities
Support functional, environmental, and qualification testing campaigns
Troubleshoot and resolve manufacturing, integration, and test-related hardware issues and non-conformances
Contribute to iterative design improvements based on manufacturing and test results
