About the Role

Job Summary
As a Radiation Effects engineer, you will serve as one of the points of contact for all technical topics related to space environment qualification and design, and meet team members' needs, customer requirements, and company goals. In this role you will serve as a focal for spacecraft electronics radiation susceptibility with the responsibility of hardening reliable space systems. This position requires deep technical expertise in radiation effects testing and analysis.

Responsibilities
You are responsible for enforcing the Radiation Hardness Assurance for our various buses, products and individual components. You will coordinate closely with all products designers to continually evolve, test, and maintain a radiation parts and materials library. You will also provide radiation analysis capabilities to ensure spacecraft shielding and electronics design is adequate for compliance to harsh environments ranging from LEO to GEO.

• 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

Basic 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 (e.g. AE9/AP9/SPM, CREME96, OMERE, SPENVIS) for environmental definition and requirements definition.

• 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, 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

Preferred Skills and Experience

• 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, etc.)

• 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
