About the role

Serve as technical owner for complex PBF hardware families, process-control systems, qualification changes, or high-risk manufacturing issues
Make clear technical recommendations under uncertainty, including risk acceptance, containment, retest strategy, production recovery, and long-term corrective action
Represent PBF in program-level reviews, quality escalations, audit discussions, supplier/vendor technical conversations, and strategic planning

Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity.
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.
Own build preparation, print programming strategy, manufacturing planning, and technical execution for assigned PBF hardware or product groups
Provide feedback to design team on printability, DfAM improvements, part consolidation opportunities, and manufacturability trade-offs
Develop and maintain controlled PBF process documentation, build standards, work instructions, verification plans, and engineering decision records
Translate design, materials, quality, and production requirements into robust build strategies, verification plans, and manufacturing execution paths

Experience with EOS production platforms (M400-4, M450-4, M4K), aerospace flight hardware, AS9100 environments, qualification campaigns, M&P release processes, or high-rate manufacturing ramp-ups
Knowledge of non-destructive inspection/evaluation (NDI/NDE) methods (CT, X-ray, UT, dye penetrant)
Experience using Jira, MES/ERP systems, Power BI, Tableau, Python, Minitab, or other tools for workflow management and technical data analysis
Strong technical communication skills including specifications, decision records, corrective action summaries, executive-ready risk narratives, and the ability to present to technical and non-technical audiences
Nice to haves but not required:

Bachelor's degree in Mechanical Engineering, Materials Science, Manufacturing Engineering, Aerospace Engineering, or related field
4+ years industry experience in metal additive manufacturing
aerospace manufacturing environment
Deep understanding of laser powder bed fusion process controls, qualification logic, manufacturing risk, inspection feedback loops, and documentation requirements
Experience owning additive manufacturing products through the AM lifecycle (work orders, non conformances, etc.)
through machining and further post processing
certifying for aerospace applications
Expertise in post-processing techniques for improved part quality (heat treatment, HIP, machining, surface finishing)

At Relativity Space, we are committed to transparency and fairness in our compensation practices.

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.
is only one part of our total rewards package.

The Powder Bed Fusion Additive Manufacturing team is pushing the boundaries of what's possible in rocket propulsion hardware.
Responsible for development, process, and production, the team oversees initial concept to final hardware with rigorous quality and precision.
From developing print parameters on state-of-the-art 3D printers to enabling fast iteration for partner departments, the team plays a critical role in taking engine designs from concept to hot fire.
The team was instrumental in producing Aeon 1 engines for Terran 1 launch and is now pioneering next-generation processes and designs for our Aeon R engines that will power Terran R.
With flight hardware production scaling up rapidly, now is the time to join and make a direct impact!
At Relativity Space, we are committed to transparency and fairness in our compensation practices.
At Relativity Space, we're building rockets to serve today's needs and tomorrow's breakthroughs.
Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level.
