  • Root cause analysis
  • Integration
• Design, document, test and troubleshoot digital and analog hardware for products using electrical engineering principles and techniques. Designs may include the use of FPGAs, processors, and DDR memory components, and industry interfaces, such as Ethernet, I2C, SPI, USB, and RS-232.
• Conduct qualification testing alongside a team of nuclear engineers for total ionizing dose, neutron interactions, dose-rate, proton interactions, and heavy-ion environments.

What You Will Learn:

• Learn, Discover and expand your knowledge about specialized Nuclear environments including:
  • Transient Radiation Effects on Electronics (TREE)
  • Single Event Effects (SEE)
  • Electromagnetic Pulse (EMP)

Qualifications You Must Have:

• Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 8 years prior relevant experience or an Advanced Degree in a related field and minimum 5 years of experience
