What Is the Job Description of a Radiation Engineer Do?

The duties of a radiation engineer are to conduct experiments that test and evaluate radiation effects in a variety of settings. Their responsibilities include providing theoretical analysis based on a test they perform in an experimental environment. Professionals in this career often focus on the performance of systems, equipment, or networks during and after exposure to radiation. While reporting their findings, a radiation engineer may suggest layouts, parts, and designs that meet requirements for operating under realistic levels of radiation.

What are the key skills and qualifications needed to thrive as a Radiation Engineer, and why are they important?

To thrive as a Radiation Engineer, you need a solid background in physics, electrical engineering, or nuclear engineering, often supported by a relevant bachelor's or master's degree. Familiarity with radiation testing equipment, simulation software (such as Geant4 or MCNP), and knowledge of industry standards like MIL-STD-883 are typically required. Strong analytical thinking, problem-solving abilities, and effective teamwork are valuable soft skills for this role. These skills and qualifications are crucial for accurately assessing radiation effects on materials and systems, ensuring safety, compliance, and performance in high-reliability environments.

What are the main challenges Radiation Engineers face when working on projects for space applications?

Radiation Engineers working on space-related projects often encounter the challenge of accurately predicting and mitigating the effects of cosmic radiation on spacecraft systems and components. This requires a strong understanding of radiation environments, materials science, and specialized testing protocols. Collaboration with design, testing, and mission assurance teams is essential to ensure that electronic systems can withstand harsh radiation without failure. Additionally, staying updated with evolving standards and simulation tools is key to delivering robust and compliant solutions.

What does a Radiation Engineer do?

A Radiation Engineer is a professional who studies and evaluates the effects of radiation on materials, electronics, and systems, particularly in environments such as space, nuclear facilities, or medical equipment. They design tests, conduct experiments, and develop methods to protect devices and people from harmful radiation. Their work is crucial for ensuring the safety and reliability of technology used in high-radiation environments. Radiation Engineers often collaborate with scientists, engineers, and regulatory agencies to develop guidelines and solutions.

How much do RF engineers earn?

Radiation engineers, including RF engineers, typically earn between $70,000 and $120,000 annually, depending on experience, location, and industry. Entry-level positions may start lower, while experienced professionals with specialized skills or certifications can earn higher salaries, especially in sectors like telecommunications, aerospace, and defense.

What is the difference between Radiation Engineer vs Medical Physicist?

AspectRadiation EngineerMedical Physicist
CredentialsBachelor's or Master's in Engineering, certifications in radiation safetyDoctorate in Medical Physics, board certification (ABMP or ABR)
Work EnvironmentIndustrial, nuclear power plants, research labsHospitals, clinics, cancer treatment centers
Industry UsageDesigning radiation systems, safety protocolsCalibrating equipment, treatment planning

While both roles involve radiation and safety, Radiation Engineers focus on designing and maintaining radiation systems in industrial or research settings, whereas Medical Physicists specialize in radiation therapy and diagnostic imaging in healthcare. The key differences lie in their work environments, required credentials, and specific responsibilities.

Kapta Space

Seattle, WA • On-site

Full-time

Posted 21 days ago

Job description

Kapta Space, a VC-funded early-stage startup in Seattle, WA, is breaking new ground in Geospatial Intelligence. Our technology centers around a proven, scalable electronically-steered radar for sophisticated spaceborne applications such as earth observation using synthetic aperture radar (SAR) techniques, as well as enabling advanced defense missions such as target tracking on the ground and in the air.
Kapta is seeking a Radiation Engineer to lead radiation analysis, testing, and qualification across Kapta's avionics and payload electronics. The radiation engineer will define the radiation environment for our missions, model system response, plan and execute radiation test campaigns, and support technical engineering design decisions to ensure on-orbit hardware reliability and performance. This role has significant scope and requires a strong, self-driven engineer capable of working independently in a fast-paced, multi-disciplinary environment.
The ideal candidate will demonstrate the ability to apply advanced technical principles, theories, and concepts, and will have the drive and discipline to complete projects independently and on time. Kapta Space recognizes that strong candidates come from diverse backgrounds; if you bring relevant experience and the capacity to grow into this role, we encourage you to apply. The position may be structured at a junior or senior level based on the selected candidate's strengths, with salary and benefits adjusted accordingly.
Role:
  • Own radiation environment definition and mapping for Kapta missions.
  • Build radiation budgets, calculate margins, and assess system-level reliability.
  • Plan and execute Single Event Effect (SEE), Total Ionizing Dose (TID), and Displacement Damage (DD) test campaigns at the component and assembly level.
  • Analyze test results, identify vulnerabilities, and recommend mitigation strategies.
  • Create and manage internal tools and workflows for radiation analysis, component qualification, and validation of component selection. Partner with engineering teams to inform component selection, derating, and architecture decisions.
  • Monitor manufacturer-issued product change notifications (PCNs) and assess their impact on radiation performance and qualification.
  • Support failure analysis and on-orbit anomaly investigations.
  • Drive improvements to internal standards for radiation modeling and verification.
  • Domestic travel required. Foreign travel possible.

Required Qualifications:
  • Bachelor's degree in Electrical Engineering, Physics, Nuclear Engineering, or related field.
  • 5+ years of experience in radiation-effects engineering for space or high-reliability electronics.
  • Experience with performing or overseeing electrical circuit analysis and implementation of radiation effects mitigations.
  • Experience with radiation environment software modeling tools and resources (example: OMERE).
  • Strong understanding of radiation effects, test methods, and test execution.
  • Hands-on experience planning and executing radiation test campaigns.
  • Experience developing analysis tools, automation, and internal data systems to support modeling, testing, and engineering workflows. Comprehensive understanding of electronics (both digital and analog), schematics, and PCB layout principles.
  • Excellent communication skills, with ability to clearly present technical findings and collaborate effectively across engineering functions.
  • Eligible to obtain and maintain an active U.S. Top Secret/SCI security clearance

Bonus if candidates have experience and skills in the following areas:
  • M.S. or Ph.D. in a relevant field.
  • Experience with radiation testing at the PCB and subassembly level.
  • Experience with FPGA/ASIC radiation characterization and mitigation.
  • Prior work in small, fast-iteration aerospace teams.
