Job summary

Apex Technology, Inc. is seeking a Radiation Effects Engineer to serve as a focal point for space environment qualification and design, ensuring hardening of spacecraft electronics for harsh environments from LEO to GEO.

You will own radiation qualification campaigns, operate test equipment, and provide radiation-tolerant recommendations to improve mission success. This role requires deep technical expertise and collaboration with product designers and external facilities.

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 (AE9/AP9/SPM, CREME96, OMERE, SPENVIS).
• Familiarity with industry radiation standards (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, including test evaluation hardware/kit development and familiar with testing FPGAs and microprocessors.
• Proficiency with data analysis and modeling software (Python, MATLAB, or equivalent).
• Familiarity with circuit simulation tools (e.g. LTSpice) with experience in design and/or analysis of digital and analog circuits.
• Strong lab experience with oscilloscopes, logic analyzers, source meters, power supplies, and automating data collection.
• Effective communication skills, with the ability to clearly convey radiation risks and mitigation to diverse stakeholders

Responsibilities

• Establish and own the 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 to increase probability of mission success through part selection, circuit design, passive/active radiation mitigations and mission design recommendations
• Support business development and mission integration efforts by contributing to 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 specific new technologies
• Provide unit and mission level radiation analyses including SEE rates, availability estimates, cumulative dose exposures and the associated artifacts for requirements verification
• Maintain and grow the parts and materials library databases with critical piece-part and material information accessible to all designers
