<p>About the Team:</p> <p>The Materials & NDE Engineering team is responsible for the development, characterization, and inspection of materials across the Terran R launch vehicle. We specialize in rapid implementation of material systems through robust internal testing capabilities and first principles driven qualification approaches. We have recently made our first primary structure barrel, supported introduction of next generation powder additive alloys in the Aeon-R engine, and developed 100% in-cell NDE inspection capabilities for WAAM manufactured hardware.</p> <p>The additive technology team leads research and development of Relativity's Stargate 3D-printing platform and factory operating system to produce large-scale metal structures for the industrial base. The team works with robotics engineers, data scientists, systems engineers, and welders to advance Relativity's innovative tech stack, which leverages autonomy, advanced simulation, machine learning, and robotics. Working at the intersection of hardware and software, the team is creating a unified platform that can perform additive manufacturing, in-situ monitoring, NDE, and subtraction capabilities in a single print cell. Progressing in parallel to Terran R development, Relativity's breakthroughs in large-scale additive manufacturing have the potential to revolutionize the defense industrial base.</p> <p>About the Role:</p> <ul> <li>Responsible for advancing the characterization of our additively manufactured (AM) directed energy deposition (DED) materials, specifically quantifying and improving our internal understanding of material micro/ macrostructure </li><li>While this role will supplement Relativity Space's vehicle development goals through the Materials & Processes team's shared vision, this role will cover a breath of alloys across the aerospace, marine, and defense industries.
