JOB DUTIES AND RESPONSIBILITIES

• Support radiation effects analyses for electronic components, integrated circuits, and electrical subsystems supporting products and platforms.
• Perform radiation assessments, component evaluations, shielding analyses, and worst-case analyses to support radiation-tolerant hardware designs.
• Review radiation environments, component specifications, engineering data, and technical documentation while supporting radiation effects engineering activities.
• Support radiation testing, characterization, data collection, and design validation activities.
• Analyze total ionizing dose (TID), single event effects (SEE), displacement damage, laboratory measurements, and engineering data while documenting findings.
• Assist with design verification, root cause investigations, engineering changes, and qualification activities supporting product development.
• Cross-Functional Engineering Support
• Collaborate with electrical, hardware, FPGA, systems, software, mechanical, manufacturing, integration and test, quality, and program teams supporting radiation effects engineering activities.
• Prepare radiation analyses, technical reports, test procedures, qualification documentation, and design review materials supporting engineering decisions.
• Support design reviews, technical discussions, hardware integration, and engineering investigations throughout the product development lifecycle.
• Maintain radiation analysis documentation, test results, qualification records, and configuration-controlled technical data.
• Apply engineering standards, radiation analysis practices, company procedures, and customer requirements throughout product development.
• Recommend improvements that enhance radiation tolerance, product reliability, and design quality.

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS

• Bachelor's degree with 0–2 years of related experience in electrical engineering, physics, nuclear engineering, aerospace engineering, or a related engineering field.
• Direct experience performing many or all of the responsibilities listed above.
• Direct experience working with automotive and high volume commercial grade parts in radiation environments.
• Good understanding of the radiation physics relevant to electronic components.
• Excellent written and spoken communication ability.

PREFERRED EXPERIENCE

• Experience with ray tracing tools such as FASTRAD
• Experience with radiation susceptibility of RF components including III-V transistors (GaAs, Gan)
• Specialization of SEE analysis and test of complex digital devices such as FPGAs, processors,  and memories (RAM and NVM)
• Working knowledge of Electronic Circuit Theory.
• Basic programming and scripting, such as Python.
• Managing databases of component test data.
