Sr Additive Manufacturing Engineer, PBF

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll 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 were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

The Powder Bed Fusion Additive Manufacturing team is pushing the boundaries of whats 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!

About the Role:

• Serve as technical owner for complex PBF hardware families process-control systems qualification changes or high-risk manufacturing issues
• 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
• Define and improve PBF process specification architecture change-control logic verification requirements acceptance criteria and release documentation
• Develop and maintain controlled PBF process documentation build standards work instructions verification plans and engineering decision records
• Lead cross-functional technical investigations involving material failures machine errors inspection deviations process escapes hardware risk and recurring nonconformances
• Translate design materials quality and production requirements into robust build strategies verification plans and manufacturing execution paths
• Drive qualification and requalification strategy for changes to parameters machines powder heat treatment post-processing inspection methods or product-specific controls
• Make clear technical recommendations under uncertainty including risk acceptance containment retest strategy production recovery and long-term corrective action
• Build scalable systems such as decision-ticket frameworks dashboards standards readiness reviews lessons-learned libraries and ownership models
• Mentor Level I and Level II engineers review their technical work and raise the teams standard for crisp writing evidence-based decisions and partner-team alignment
• Represent PBF in program-level reviews quality escalations audit discussions supplier/vendor technical conversations and strategic planning
• Identify department-level improvement opportunities that increase throughput reproducibility audit readiness and hardware quality without creating unnecessary bureaucracy

About You:

• Bachelors 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
• Experience in developing analyzing qualifying and certifying AM parts for production; certifying for aerospace applications
• Expertise in post-processing techniques for improved part quality (heat treatment HIP machining surface finishing)
• Experience with Additive Manufacturing tools such as EOSprint Magics 3dxpert Flow and CAD tools such as Siemens NX (preferred) or Solidworks
• Proven track record of leading ambiguous technical investigations and driving cross-functional decisions to closure
• Ability to influence without authority and drive alignment across engineering operations quality and leadership
• 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:

• 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)
• Familiarity with statistical process control (SPC) design of experiments (DOE) machine qualification metallurgical analysis CT/inspection data analysis thermal processing or supplier technical management
• Experience using Jira MES/ERP systems Power BI Tableau Python Minitab or other tools for workflow management and technical data analysis
