What you will do

• Design, specify, and qualify in-core and ex-core detector systems for neutron flux and radiation monitoring.
• Support detector response modeling and verification using radiation transport codes.
• Evaluate and validate sensor survivability and performance under high-temperature, high-radiation, and accident-condition environments.
• Partner with reactor control and data acquisition engineers to integrate sensor outputs.
• Support V&V of instrumentation against customer and regulatory requirements.
• Collect requirements and provide expertise to engineers in other functional areas.
• Other nuclear instrumentation and sensor design/analysis duties as assigned.

Required qualifications

• Bachelor's degree in nuclear engineering or equivalent degree from an accredited institution.
• 1-2+ years of nuclear engineering industry experience (MS equivalent to 2 yrs), with exposure to radiation detection or instrumentation.
• Experience with radiation transport methods, including with codes such as MCNP/OpenMC/Serpent.
• Proficient in at least one of the following programming languages: Python, C++, C#, FORTRAN, or another scientific computing language.
• Basic knowledge of thermal hydraulic principles.
• Self-motivated with strong organizational, written, and oral communication skills.
• Experience working in an engineering organization and developing high-quality work.
• Must work 100% onsite at El Segundo HQ.

Nice to have

• Hands-on experience designing, testing, or qualifying sensors/instrumentation in harsh environments (high temperature, high radiation).
• Experience with data acquisition (DAQ) systems and integration with reactor control systems.
• Experience with variance reduction techniques and associated software (Attila4MC and/or ADVANTG), is a plus.
• Competency in distributed software development processes and high-performance computing environments.
• Familiarity with CAD design software (NX, SolidWorks, and/or SpaceClaim), is a plus.
• Familiarity with dose consequence methods and software such as MAACS or NRC-RADTRAN.
• At least 1 year of software development or scripting experience.
• Hands-on experience designing hardware and/or performing tests.
