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.


As a member of our fast-paced Radiation Effects team, you will be responsible for ensuring avionics hardware performance through some of the harshest and varied radiation environments imaginable. In order to ensure maximum reliability in an ionizing radiation environment, the Radiation team at SpaceX performs exhaustive analysis, design, and test at the component, board, unit and subsystem levels with extensive opportunity to interact with a vast array of rocket and spacecraft hardware and electronics. As one of the few teams required to interface with the design, manufacturing, integration, and mission operations teams, we play a critical role in the development of our systems as we advance our efforts towards broadband satellite internet and safe, reliable, inexpensive, and innovative access to space with the fundamental goal of expanding human space exploration capabilities.


  • Perform circuit, sub-system, and system level engineering and risk assessment due to ionizing radiation effects
  • Establish applicable ionizing radiation requirements
  • Predict environmental stresses to vehicles flown in ionizing radiation environments
  • Conduct analysis and presentations for project mission managers, guidance navigation and control teams, and payload customers
  • Work closely with responsible engineers, manufacturing engineers, and production test labs to ensure a testable product is being developed
  • Work with circuit design, electronics manufacturing, and software implementation to analyze and improve test coverage
  • Assess design and flight reliability based on system design and predicted radiation response
  • Make recommendations for design, process improvements, and data collection
  • Perform root-cause analysis of test failures and communicate recommended actions
  • Define and implement project plans, manage milestones, and hold reviews to assure reliability of projects plan
  • Write verification test plans, test procedures, and test reports against product requirements

  • Previous work experience in radiation effects including modeling, testing, and/or analysis
  • Experience in using one or more radiation computational simulation tools (eg. GEANT4, MCNPX, NOVICE, SpaceRad, FASTRAD or CRˆME)
  • Knowledge/experience in the effects of UV and atomic oxygen on materials and components
  • Experience in analysis, control and mitigation for spacecraft charging
  • Experience with meteoroid/orbital debris, electron/proton/x-ray transport, and atomic oxygen calculations
  • Strong skills in mathematics and statistics
  • Computational experience in programming languages: Python, Matlab, C/C++, and SQL
  • Excellent written and verbal communication skills
  • Proficiency with avionics hardware spanning integrated circuits, PCBA boards, sensors/transducers, functional troubleshooting and defect detection
  • Proficiency with hardware blueprints/schematics and circuit functions based on designs
  • Superior organizational and analytical skills with keen attention to detail and quality
  • Radiation dose safety training  


  • Must be able to work extended hours and weekends as needed
