Launch Mechanical Engineer II - Launch Structures

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. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

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. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

About the Team:

The Launch team operates at the intersection of every major aspect of Terran R, from stages and payloads to ground systems, launch, landing, and refurbishment. The Cape is the only place where you see it all come together, offering a level of exposure and responsibility unmatched elsewhere in the program. This is where first flights happen, where history is built on top of history, and where the scale of what's underway is unlike anything in modern aerospace. The mission stays the same, but the work evolves with every milestone: from first launch to reuse, high-cadence operations, and beyond. If you're looking to define what's next in space launch and write a new playbook, not just repeat what’s already been done, this is where it happens.

About the role:

As a Launch Mechanical Engineer, you will be at the forefront of creating a world class orbital launch site. In order to be successful in this role, you should be someone who thrives in ambiguity and is able to lead projects into completion. Ideally, you are someone who has come from a fast paced, aerospace or mechanical engineering environment, having completed difficult projects while collaborating effectively with other key groups. Pressure around timelines, cost, and quality unleash the best in you, while finding creative ways to optimize across trade-offs. This role requires the highest attention to detail, while being able to abstract from day-to-day challenges while ensuring alignment on high-level objectives. Excellent judgement and analytical skills are a must, as well as a high degree of professional ethics and integrity. You bring curiosity for our unique technology and our production processes and are eager to develop a next generation launch site.

In this role, you will be responsible for end-to-end hardware design, with a strong emphasis on ownership and accountability. Your day-to-day tasks will include working within our CAD environment (NX), conducting FEA analyses using Nastran and/or ANSYS, and performing supporting hand calculations. You will collaborate closely with the launch site civil and fluids engineering teams, various vehicle engineering groups, and the test team. Additionally, you may contribute to the development and review of procedures for testing or operating the equipment you design and analyze. This position also involves coordination with both in-house and external fabrication partners to ensure successful hardware delivery.

About you:

Bachelor’s degree in mechanical, aerospace, or a related engineering field

Minimum 2 years of experience in full-cycle mechanical design

Proficient in 3D CAD software (e.g., NX, Creo, SolidWorks, CATIA)

Strong foundation in structural mechanics and engineering analysis

Ability to manage multiple projects and meet evolving requirements

Strong communication and teamwork skills

Nice to haves but not required:

4+ years of full-cycle mechanical design experience

Familiarity with aerospace standards (NASA, DoD, USAF, AFSPCMAN 91-710)

Experience with large structures, mechanisms, or launch ground systems

Proficient with ANSYS, FEMAP, and advanced NX usage

Understanding of industry codes (e.g., AISC, ACI, AWS, ASTM, ASME, NFPA)

Experience checking drawings and applying GD&T standards

Successful candidates must clear a background check administered by the US government to obtain clearance for on-site work at our government partner location in Cape Canaveral, Florida.
