Radiation Engineer II

True Anomaly•Long Beach, CA

1d•$90,000 - $130,000•Hybrid

About The Position

True Anomaly is seeking a skilled Radiation Engineer II to support the radiation analysis, component testing, and mitigation strategy development for our spacecraft electrical systems. You will be a key technical contributor to radiation hardness assurance across our programs — developing environment models, executing test campaigns, and maintaining the parts library that underpins our mission reliability. You bring hands-on experience with radiation test facilities, strong analytical skills, and the ability to communicate radiation and reliability risks clearly to engineers and program stakeholders alike.

Requirements

Bachelor's degree in Physics, Electrical Engineering, Nuclear Engineering, or related field
2-4 years of professional experience in space radiation engineering or a related discipline
Proficiency with radiation environment modeling tools such as AE9/AP9/SPM, CREME96, OMERE, or SPENVIS
Familiarity with radiation test standards including MIL-STD-750, MIL-STD-883, ECSS-Q-ST-60-15C, and NASA testing guidelines
Experience planning and executing SEE, TID, and DDD test campaigns
Proficiency with data analysis and modeling software (Python, MATLAB, or equivalent)
Strong lab experience with oscilloscopes, logic analyzers, source meters, power supplies, and automated data collection
Excellent written and verbal communication skills
Must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

Nice To Haves

Master's or Ph.D. in Electrical Engineering, Physics, Reliability Engineering, or related field
Familiarity with Radiation Hardness by Design (RHbD) principles
Familiarity with radiation transport and shielding analysis tools (NOVICE, FASTRAD, GEANT4)
Familiarity with circuit simulation tools such as LTSpice or PSpice
Familiarity with space charging effects on materials and electronics
Customer-facing experience presenting radiation and reliability assessments at design reviews
Experience working in a fast-paced, startup environment or a similarly dynamic setting

Responsibilities

Develop TID, SEE, and DDD models for any orbital regime using industry-standard tools and best practices
Budget, schedule, plan, and execute radiation test campaigns at external facilities (protons, heavy ions, gamma, neutron) or through third-party partners
Provide unit and mission-level radiation analyses including SEE rates, availability estimates, lifetime TID and DDD exposures, and associated artifacts for requirements verification
Support reliable part selection, circuit design, and passive and active radiation mitigation strategies to increase probability of mission success
Maintain and grow the parts library database with critical radiation and reliability information
Assist in developing radiation and reliability engineering processes and provide cross-discipline training to instill a culture of survivability awareness
Support proposal writing, requirements development, schedule baselines, customer briefings, and design reviews (SRR, PDR, CDR) with credible radiation and reliability analyses
Communicate product development status and issues with leadership and stakeholders
