SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.


The Additive Manufacturing Engineer is responsible for design, development, and testing of all facets of the additive process with a focus on machines, software, part design and analysis, and additive techniques.


  • Drive and identify projects to make the printer platforms more robust and repeatable based on machine issues, failed builds, and sensor monitoring/in process data acquisition.
  • Be an active contributor within a team of engineers who perform the design, development, and testing of all facets of the additive process using powder-bed and powder-fed approaches.
  • Continually identify and implement process improvement efforts on every step of the additive process.
  • Advise and collaborate with the design team to incorporate and optimize features for additive manufacturing.
  • Generate/optimize build files to produce high quality parts in minimum time with maximum consistency.
  • Work with materials engineers to investigate properties, geometric accuracy, and surface finish results to develop optimal print parameters, heat treatments, and design allowable for existing and new alloys.
  • Develop and maintain systems to efficiently collect and analyze process data while minimizing collection/entry burden.
  • Develop and document best practices on new equipment and processes.
  • Identify and implement safety improvements throughout the additive manufacturing process.


  • Bachelor’s degree in mechanical, materials, or other engineering discipline.
  • 1+ years of professional or internship experience in a manufacturing environment or role.


  • Master’s degree in aeronautical, astronautical, or mechanical engineering.
  • Experience with operating additive machines, including parameter development and process control.
  • Experience with trouble shooting/repairing machines.
  • Knowledge of various additive and subtractive manufacturing and joining techniques for metals.
  • Solid understanding of optics and lasers.
  • Knowledge of relevant aerospace design and test specifications, such as SMC-S-016, NASA-STD-5009, AIAA-S-080, and NASA-STD-5017.
  • Familiarity with common engineering materials properties (strength, life, thermal, fluid compatibility etc.) and processing attributes particularly for titanium or nickel-based alloys.
  • Ability to perform trade studies using first principles and engineering fundamentals.
  • Proficient in basic principles of compressible and incompressible flow, thermodynamics, thermochemistry, mechanics, materials, and electrical circuits.
  • Hands-on experience with aerospace component or fluid system testing, including pressure, hot-fire, and environmental testing.
  • Excellent communication skills and ability to succinctly present recommendations.
  • Passion for advancing the commercial space industry and human spaceflight.
  • Able to work well in an integrated collaborative team environment.
  • Highly self-motivated and able to prioritize and execute tasks in a high-pressure environment.
