What is an aerospace radiation engineer?

An Aerospace Radiation Engineer is a specialized professional who studies and manages the effects of radiation on aerospace systems, such as satellites, spacecraft, and avionics. They analyze how cosmic rays and solar radiation impact electronics and materials in space, and develop strategies to mitigate these effects. Their work is critical for ensuring the reliability, safety, and longevity of aerospace missions, particularly in harsh space environments. Aerospace Radiation Engineers often collaborate with scientists, engineers, and mission planners to design shielding, select materials, and test components for radiation tolerance.

What are the key skills and qualifications needed to thrive as an aerospace radiation engineer?

To thrive as an Aerospace Radiation Engineer, you need a solid background in physics, electrical engineering, or a related field, often supported by a relevant bachelor's or advanced degree. Familiarity with radiation analysis tools (such as SPENVIS or GEANT4), radiation testing protocols, and standards like MIL-STD-883 are typically required. Strong analytical thinking, attention to detail, and effective communication are crucial soft skills for interpreting complex data and collaborating with multidisciplinary teams. These skills ensure accurate assessment and mitigation of radiation effects on aerospace systems, which is vital for mission safety and equipment reliability.

What are some common challenges aerospace radiation engineers face when working on spacecraft systems?

Aerospace Radiation Engineers often encounter challenges related to accurately predicting and mitigating the effects of space radiation on electronic components and materials used in spacecraft. They must account for varying radiation environments depending on mission profiles, such as low Earth orbit versus deep space, and balance protection measures with weight and budget constraints. Additionally, collaborating closely with design, testing, and mission assurance teams is crucial to ensure that all systems meet reliability standards without over-engineering solutions.

Key responsibilities

  • Lead radiation analysis, testing, and qualification of avionics and payload electronics.

  • Define radiation environment parameters, model system response, and support design decisions to ensure hardware reliability.

  • Plan and execute radiation test campaigns including SEE, TID, and DD testing at component and assembly levels.

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.
