Space Radiation Engineer Jobs (NOW HIRING)

Denver, CO or Long Beach, CA

Space is a warfighting domain. True Anomaly seeks those with the talent and ambition to build the technology that secures it.

True Anomaly delivers decisive capabilities for space superiority. We build autonomous spacecraft, advanced payloads, mission software, and space-based interceptors — enabling the U.S. and its Allies to secure the space environment and counter threats from the ultimate high ground.

Be the offset. We create asymmetric advantages with creativity and ingenuity.

What would it take? We challenge assumptions to deliver ambitious results.

It's the people. Our team is our competitive advantage and we are better together.

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.

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 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

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

Base Salary: DEN: $90,000 - $125,000 | LB: $95,000 - $130,000

Equity + Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, location, and experience.

Work Location —Successful candidates will be located near Denver or Long Beach locations. While we observe a hybrid work environment, most work must be done on site.

Work environment —the work environment; temperature, noise level, inside or outside, or other factors that will affect the person's working conditions while performing the job.

Physical demands —the physical demands of the job, including bending, sitting, lifting and driving.
