The Role

As a Radiation Effects Engineer, you serve as a technical focal point for space environment qualification and design. You will harden reliable space systems by managing radiation susceptibility across Apex's satellite bus platforms, with responsibility for enforcing Radiation Hardness Assurance across products, components, and systems destined for LEO through GEO.

Your Responsibilities

  • Establish and own radiation qualification campaigns for critical new generation electronics
  • Operate radiation test equipment including total dose sources and pulsed laser equipment
  • Provide radiation-tolerant recommendations to product designers covering part selection, circuit design, passive/active mitigations, and mission design to increase mission success probability
  • Support business development and mission integration through proposals, requirements development, customer briefings, and design reviews (SRR, PDR, CDR) with radiation assessments
  • Own the budget, schedule, plan, and execution of radiation test campaigns at external facilities (protons, heavy ions, gamma, neutron) or through third-party partners for new technologies
  • Provide unit and mission-level radiation analyses including SEE rates, availability estimates, cumulative dose exposures, and verification artifacts
  • Maintain and grow the parts and materials library databases with critical piece-part and material information accessible to all designers
  • Coordinate closely with product designers to evolve, test, and maintain radiation parts and materials library

Required Qualifications

  • B.S. in Electrical Engineering, Physics, Nuclear Engineering, or related field
  • 2-5 years of experience in radiation effects and/or reliability engineering for aerospace systems
  • Expertise with radiation tools (AE9/AP9/SPM, CREME96, OMERE, SPENVIS) for environmental and requirements definition
  • Familiarity with industry radiation standards (MIL-STD-750, MIL-STD-883, ECSS-Q-ST-60-15C, MIL-STD-3053, NASA testing guidelines)
  • Experience budgeting, scheduling, and executing SEE, TID, and DDD test campaigns including test evaluation hardware development and FPGA/microprocessor testing
  • Proficiency with data analysis and modeling software (Python, MATLAB, or equivalent)
  • Familiarity with circuit simulation tools (e.g. LTSpice) with experience designing or analyzing digital and analog circuits
  • Strong lab experience with oscilloscopes, logic analyzers, source meters, power supplies, and automating data collection
  • Effective communication skills to convey radiation risks and mitigations to diverse stakeholders

Preferred Qualifications

  • M.S. or Ph.D. in Electrical Engineering, Physics, Reliability Engineering, or related field
  • Hands-on experience with scripting, automation, and programming languages (Python, MATLAB, JMP, C/C++, SQL)
  • Familiarity with radiation transport and shielding analysis tools (FASTRAD)
  • Familiarity with space charging effects on materials and electronics
  • Experience with anomaly resolution and documentation of anomaly reports and lessons learned databases
