Radiation Engineer II

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. This role serves as 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 will 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.

• 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.

• Bachelor’s degree in Physics, Electrical Engineering, Nuclear Engineering, or a 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, CREME
  96, 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.

• Master’s or Ph.D. in Electrical Engineering, Physics, Reliability Engineering, or a 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.

• Base Salary:
  Denver – $90,000 – $125,000;
  Long Beach – $95,000 – $130,000.
• Equity + Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401(k), Parental Leave.

• Work Location – Successful candidates will be located near Denver or Long Beach. Hybrid work environment; most work must be done on site.
• Physical demands – bending, sitting, lifting, driving, and other typical responsibilities of the role.
