What is a radiation effects engineer?

A Radiation Effects Engineer evaluates and mitigates the impact of ionizing radiation on electronic components and systems, primarily for aerospace, defense, and space applications. They analyze radiation environments, perform testing, and develop shielding or design strategies to ensure reliable operation in harsh conditions. Their work is crucial for satellites, space probes, and high-altitude electronics where radiation exposure can cause failures or degradation.

What skills and qualifications are needed to be a radiation effects engineer?

To thrive as a Radiation Effects Engineer, a strong background in physics, electrical engineering, or a related field, alongside expertise in radiation effects on electronic systems, is typically required. Familiarity with simulation tools such as SPICE, radiation test equipment, and industry standards like MIL-STD-883 or ESA standards, as well as relevant certifications like IEEE, is essential. Strong analytical thinking, problem-solving abilities, and effective communication are key soft skills for success in multidisciplinary teams. These competencies ensure effective assessment and mitigation of radiation risks, which are critical for the reliability and safety of aerospace and electronic systems.

What challenges do radiation effects engineers face?

Radiation Effects Engineers often encounter the challenge of accurately predicting how electronic components will respond to various forms of radiation, particularly in space or nuclear environments. Staying updated with evolving standards and ensuring compliance with stringent testing protocols can be demanding. Additionally, they must frequently collaborate with design teams, test engineers, and clients to integrate radiation-hardened solutions efficiently into complex systems. Addressing unexpected test results or failures requires both rigorous analytical skills and adaptability, making the role both technically demanding and intellectually rewarding.

What does a radiation effects engineer do?

A radiation effects engineer designs and tests electronic components and systems to ensure they can withstand radiation exposure, often for aerospace, military, or nuclear applications. They analyze radiation environments, perform simulations, and develop mitigation strategies using specialized tools and industry standards.

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 Lead Radiation Effects 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 level may be restructured based on the selected candidate’s strengths, with salary and benefits adjusted accordingly.

Role
  • Develop and own the company's radiation assurance strategy, defining the philosophy, requirements, and decision framework that govern radiation testing, component selection, and radiation-tolerant system design.
  • Build radiation budgets, calculate margins, analyze mission environments, 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 reliability analysis as it pertains to radiation effects.
  • 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 high-reliability electronics.
  • 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.
  • Working knowledge of electrical schematics, including the ability to identify common components, understand basic signal flow, and locate relevant circuit information.
  • Strong communication skills and the ability to work across disciplines.
Bonus if candidates have experience and skills in the following areas:
  • M.S. or Ph.D. in a relevant field.
  • Experience with performing or overseeing electrical circuit analysis and implementation of radiation effects mitigations
  • Comprehensive understanding of electronics (both digital and analog), schematics, and PCB layout principles.
  • Scripting and SW development experience for data analysis and test automation using Matlab or Python.
  • Prior experience with system reliability calculations and roll-up particularly as it pertains to radiation risks.
  • Experience developing PCB schematics and layout with an ECAD tool (Eg.: Altium, KiCAD, OrCAD, ect).
  • 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.
