Senior Mechanical Engineer, Factory Automation

About the Company

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time.

About the Team

The Tooling and Factory Automation team sits at the intersection of design, manufacturing, and automation, making everything from large-scale structural fixtures to small tools that directly enable Terran R’s production. As a design group embedded within the manufacturing organization, we dig deep into the needs of our internal partners to understand root problems, propose solutions, and deliver hardware to help build faster, scale smarter, and work better. The team is also at the forefront of Relativity’s growing factory automation efforts, an increasingly critical part of scaling production of Terran R at existing and future facilities.

About the Role

The Mechanical Design Engineers are responsible for the design and development of tools and factory automation equipment that support manufacturing. The Mechanical Engineering team works closely with Design and Manufacturing, turning top-level requirements and concepts into functional delivered equipment.

• Develop high quality development and production tooling and automation solutions for the Terran vehicle and Aeon engine programs
• Capable of integrating concepts and principles of mechanical design and analysis of several different projects in a fast-paced environment—projects will vary in size and scale
• Ability to interpret and apply sound design and drafting standards (ASME Y14.5) in creating tooling drawing definitions
• Handle a wide range of technical problems and familiar with all types of material handling, assembly fixtures, off-loaders, rotisseries, test fixtures, structural weldments, environmental chambers, and custom machines
• Close collaboration with component designers, manufacturing engineers, and integration engineering to achieve the best possible cradle-to-grave metrics (safety, cost, quality, cycle time, delivery, reliability, life, and maintenance/refurbishment)
• Manage projects including vendor selection, fabrication, inspection, equipment installation, and commissioning of tooling

Requirements

• Bachelor of Science degree in manufacturing engineering, mechanical engineering or equivalent
• 6+ years of work or project experience with design, build, and commissioning of tooling and fixtures for manufacturing, assembly and test
• Experience using CAD and FEA-based analysis software (NX and ANSYS Workbench preferred) for structural applications
• Experience in full-cycle project completion
• Experience in strategic buildout and project management of tooling supporting production

Nice to Haves

• Strong expertise in design for manufacturability and design for assembly including experience taking products from prototype design to production
• Solid understanding of common manufacturing materials, GD&T, and tolerance/stack-up analysis
• Solid understanding of common manufacturing processes and machines including mills, lathes, welding, sheet-metal bending, lifting/rigging, assembly, inspection, etc.
• Experience with custom machine design: motors, actuators, linear rails/actuators, pneumatics, bearings, etc.
