Job Summary

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 Materials and NDE (Non-Destructive Evaluation) team plays a central role in enabling Terran R to fly re-fly and scale: developing characterizing and inspecting materials and processes across all parts of the vehicle. From welding and additive manufacturing to advanced composites the team works at the intersection of innovation and execution balancing performance and reliability with cost quality and schedule. As we move toward first flight and beyond the challenges become more exciting offering opportunities to shape how we design and develop for re-use. With ownership across products systems and disciplines engineers gain broad exposure and drive key decisions across design manufacturing and operations.

About the Role:

  • Be the M&P discipline expert for all weld materials & processes at Relativity Space
  • Qualify weld materials and products for flight reuse
  • Drive system level requirements and workflows to qualify welded products for damage tolerant design inspection flight and reuse
  • Develop implement and maintain technical specifications and engineering standards for weld materials & processes
  • Drive weld development optimization in partnership with weld engineering
  • Interface with:
    • Weld Engineering to qualify and iterate weld processes
    • Materials engineering product owners to qualify weld process usage through full product lifecycle including failure analysis (part concept to retirement)
    • Laboratory staff to characterize weld materials and processes
    • Design Engineers for weld properties allowables integration in product analysis and design
    • Manufacturing Engineers to reduce cost rate while maintaining needed performance from our weld materials
    • Quality assurance to facilitate specification compliance validation across all weld processes
    • Relativity Customer Fracture Control Boards to achieve vehicle reuse with welded products
    • Company Leadership to elevate risks and power through roadblocks

About You:

  • Bachelors degree in materials science or engineering or related field
  • 5 years of relevant materials engineering experience
    • Leveling is flexible and will be adjusted for candidates with more experience
  • Experience in process-structure-property-performance problem solving to weld materials
  • Experience with general aerospace hardware M&P activities such as material selection weld process development and qualification damage tolerance inspections risk assessments and failure analysis
  • A core commitment to accountability collaboration and execution
  • A desire to establish and foster strong interdisciplinary relationships across the company
  • An authentic introspective and inclusive mindset towards technical interpersonal team growth and development
  • Passion to work in a fast-paced and challenging environment on constantly iterating launch vehicle products driving big impact on critical program needs as we ramp manufacturing rate achieve reuse

Nice to haves but not required:

  • Industry-leading experience in weld materials & processes for production of reusable aerospace parts
  • Expertise in aerospace friction stir fusion welding (Laser Welding Orbital Tube Welding EBW GTAW GMAW etc.) and downstream effected processes (heat treat coatings passivation precision cleaning etc.)
  • Expertise in applying AWS D17.1 D17.2 or internally developed requirements for weld process qualification of nickel ferrous aluminum or titanium metal alloy systems
  • Expertise in welded aerospace products (tubes bellows additively manufactured parts plate/sheet/bar forgings castings)
  • Knowledge of relevant materials engineering disciplines (media compatibility non-destructive evaluation corrosion fatigue and damage tolerance)
  • Expertise in statistical experimental design and design allowable calculation methodology
