Position Overview
We are seeking a motivated Radiation Assurance Engineer (Electronic Components & Subsystems) to join our team assessing the suitability of electronic components and subsystems for operation in orbit. The successful candidate will analyze electronic parts and systems, design and build radiation test hardware, execute radiation test campaigns, and provide technical assessments on component performance in harsh space environments. This is a hands-on, laboratory-focused role within fast-paced engineering projects that require strong electronics design expertise and a proactive problem-solving mindset.
Key Responsibilities:
• Analyze electronic components and subsystems, including datasheets, functional architectures, and operating modes, to define radiation assessment strategies and testing requirements.
• Design schematics, PCB layouts, test boards, fixtures, and daughterboards to evaluate devices under representative operating conditions.
• Build, integrate, troubleshoot, and validate electronic test setups, including power, signal generation, biasing, loading, and data acquisition systems.
• Operate laboratory instrumentation such as oscilloscopes, power supplies, electronic loads, multimeters, source-measure units, and data loggers.
• Develop and maintain test automation, control, and monitoring scripts using tools such as Python and LabVIEW.
• Support and execute radiation test campaigns at external irradiation facilities, including setup, installation, operation, troubleshooting, and data collection.
• Analyze radiation test results, assess device degradation and failure mechanisms, and evaluate performance against mission requirements.
• Prepare detailed test plans, procedures, technical reports, and radiation assurance assessments.
• Collaborate with hardware, systems, and mission engineering teams to support design decisions and risk mitigation strategies.
• Maintain laboratory equipment, test hardware inventory, and technical documentation to enable efficient project execution and reuse of test setups.
Qualifications
Education:

Experience:
A minimum of 1-4 years of hands-on experience in electronics hardware design, testing, or a related engineering field. Relevant internships, research projects, and academic experience may be considered for junior candidates.
Preferred Qualifications:
• Master's degree in Electronics Engineering, Space Engineering, or a related discipline.
• Knowledge of radiation effects on electronics, including Total Ionizing Dose (TID), Single Event Effects (SEE), and Displacement Damage Dose (DDD).
• Familiarity with industry radiation test standards such as ESCC 22900, ESCC 25100, MIL-STD-883 TM1019/TM1017, and JESD57/JESD89.
• Experience supporting radiation test campaigns, EEE component engineering, or space-qualified hardware programs.
• Proficiency in Python, LabVIEW, MATLAB, or similar tools for test automation and data analysis.
• Experience with instrument control protocols such as SCPI and VISA.
• Familiarity with FPGA or microcontroller firmware development for hardware monitoring and test execution.
• Knowledge of COTS component qualification, derating practices, and reliability analysis for space applications.
Soft Skills:
• Strong analytical and problem-solving skills.
• Excellent attention to detail and commitment to accurate documentation.
• Hands-on approach with the ability to rapidly prototype and troubleshoot technical solutions.
• Strong interpersonal, collaboration, and teamwork skills.
• Effective verbal and written communication skills.
