Job description

Position: Nuclear/Senior Nuclear Engineer
Duration: Fulltime
Location: El Segundo, CA
About the Role

Client is seeking a highly motivated Nuclear Engineer responsible for developing nuclear engineering solutions for our microreactor. This may include nuclear engineering areas such as radiation shielding, criticality safety, accident dose consequence, reactor physics modeling and design, transient analysis, and radiation detection. You will lead and own nuclear engineering initiatives and studies, strategic direction, and work closely with a collaborative nuclear and engineering team in a fast-paced startup environment. The ideal candidate is passionate about advanced reactor design, detail-oriented, effectively communicates, and a tenacity to solve interesting technical challenges.

Responsibilities & Duties :

  • Ownership of Nuclear design and analysis, examples include: 
    • Shielding: Operational dose and shutdown activation analysis, waste categorization, and alignment of shielding design to customer and regulatory requirements. 
    • Neutronics: Analysis of ex-vessel reactor fluxes and energy deposition, criticality safety, and verification and validation (V&V) of the nuclear toolbox and reactor models.
    • Accident and Dose Consequence: Radiological dose consequence from different accident scenarios for the Client demonstration and production units.
    • Transient Analysis: Run coupled neutronics and thermal calculations to further understanding of the reactor dynamics of the Client reactor design. 
  • Collect requirements, provide expertise and feedback to engineers in other functional areas via clear, constructive communication. 
  • Other nuclear design and analysis duties as assigned. 

Required Qualifications & Skills:

  • 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).
  • 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.

Desired Qualifications & Skills  

  • Experience with variance reduction techniques and associated software (Attila4MC and/or ADVANTG), is a plus.
  • Strong experience with OpenMC, Serpent, MCNP, Attila4MC, MOOSE, RELAP, Pronghorn, GRIFFIN, or other similar nuclear software packages. 
  • 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.
