Principal Radiation Effects Engineer

Duties And Responsibilities

• Define mission radiation environments spectra (e.g. trapped particles, solar activity, Galactic Cosmic Radiation (GCR), etc.) and perform component and system level effects assessments.
• Model radiation transport and shielding effectiveness to inform system architecture decisions.
• Perform worst-case analysis, margin assessments, and susceptibility evaluations.
• Recommend component selection, shielding strategies, circuit level hardening techniques, and system level architectural approaches.
• Guide electronic design teams on layout, redundancy, error detection/correction, derating, and other resilience mechanisms.
• Develop radiation test plans, including TID/ELDRS, DDD/TNID, and SEE testing.
• Coordinate with external radiation test facilities and oversee execution and data analysis.
• Document results, maintain compliance evidence, and communicate performance impacts and required mitigations.
• Partner with design engineering, suppliers, reliability teams, and program management to ensure radiation requirements are flowed down and met.
• Identify risks early, recommend corrective actions, and support variance resolution.
• Provide technical leadership reviews and serve as the subject matter expert during customer engagements.

Required Qualifications

• Bachelor’s degree in Electrical Engineering, Physics, Nuclear Engineering, or related discipline (or equivalent experience).
• Minimum 10 years of experience in radiation effects engineering for aerospace, space, or defense electronic systems.
• Deep technical knowledge of radiation effects for EEE parts and other related materials.
• Proficiency in radiation modeling tools (e.g., CREME96, SPENVIS, R-GENTIC, SEAM4, GEANT4, MCNP, FASTRAD, etc.) and device level analysis methodologies.
• Demonstrated experience developing and executing radiation test campaigns at accredited facilities.
• Strong communication, leadership, and cross-functional collaboration skills.
