Position: Additive Manufacturing Engineer I
About the Team:

The Additive Development team at Relativity Space will develop, create, and operate the most advanced additive manufacturing technologies in the world. This best-in-class team makes sure that the infrastructure, materials, tools, and equipment are in place for us to rapidly iterate and print. The powder-based manufacturing team is crucial to manufacturing Aeon-1 for first launch and to developing and demonstrating groundbreaking technologies, design, and approaches for Aeon-R.

About the Role:

* Develop additive manufacturing processes to continuously improve manufacturing cost, quality, and lead time

* Produce additively manufactured components that rapidly enable high performance liquid propulsion hardware

* Holistically own and optimize the total manufacturing process including, design for additive, build file programing, manufacturing work instructions, and quality verification

* Develop, optimize, and product ionize process parameters for various alloys and machine systems and develop tools and techniques to accelerate and automate that process

* Execute material failure investigations, conduct root cause analyses, and implement corrective actions

* Develop new tools, techniques, and applications that automate existing processes and standardize on performance-based benchmarks

* Support material and process team with characterization and qualification of various alloys

About You:

* Experience implementing new engineering processes in school projects, internships, and/or clubs

* Experience communicating technical information within a diverse team

* Experience with at least one of the following:

* CAD

* Design for additive manufacturing

* GD&T

* Exposure to concepts behind laser powder bed fusion, printer primary subsystems, and post-processes

* 0-1+ years of experience working in aerospace, medical devices, or ISO environments

* 0-1+ years of experience in mechanical or materials engineering related roles

* 0-1+ years of experience working on metallic additive manufacturing

* Exposure to typical manufacturing execution systems (MES) and quality management systems

Nice to haves but not required:

* Advanced degree (MS) in Material Science, Materials Engineering, Metallurgy, Mechanical Engineering, or another related field

* Familiarity with processing large datasets and statistical data analysis software such as R, JMP, or Minitab

* Familiarity with design and operation of liquid propel lent engine systems

* Serve as materials subject matter expert on powder bed fusion team

* Proficient at oriented programming (Python, JS, C#, or Java)

* Experience in leveraging API's and real-time data sources to build applications in a production environment

* Developing APIs and building applications on them in a production environment

* Six Sigma/Lean manufacturing training
