• Coordinate with product designers to evolve, test, and maintain a radiation parts and materials library
• Provide radiation analysis to ensure spacecraft shielding and electronics design compliance
• 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 for part selection, circuit design, and mission design
• Support business development and mission integration through proposals, requirements, briefings, and design reviews
• Own budget, schedule, plan, and execution of radiation test campaigns at external facilities or through third-party partners
• Provide unit and mission level radiation analyses including SEE rates and cumulative dose exposures
• Maintain and grow the parts and materials library databases

Required qualifications

• B.S. in Electrical Engineering, Physics, Nuclear Engineering, or related field
• 3+ years of experience in radiation effects and/or reliability engineering for aerospace systems
• Expertise with radiation tools (e.g. AE9/AP9/SPM, CREME96, OMERE, SPENVIS)
• Familiarity with industry radiation standards (e.g. MIL-STD-750, MIL-STD-883, ECSS-Q-ST-60-15C, MIL-STD-3053 and NASA testing guidelines)
• Experience with budgeting, scheduling and executing SEE, TID and DDD test campaigns
• Experience with test evaluation hardware/kit development
• Familiarity with testing FPGAs and microprocessors
