Mid-Career Nuclear Engineer

Company: Black Mesa Advanced Fission, LLC

Location: Evanston, WY
Type: Full-Time
Citizenship Requirement: U.S. Citizenship Required


About Black Mesa Advanced Fission

At Black Mesa Advanced Fission, LLC, we are building tangible reactor technologies. Our team specializes in groundbreaking modeling, simulation, fabrication, and experimental validation, working at the cutting edge of nuclear engineering to address complex challenges.


Position Overview

We are seeking a highly motivated mid-career nuclear engineer who thrives on learning, experimentation, and hands-on problem solving. Ideal candidates will bring strong technical expertise in neutronics and multiphysics simulation, coupled with a passion for integrating and automating computational tools.


Required Qualifications

  • Master's or Ph.D. degree in Nuclear Engineering or related discipline
  • U.S. Citizenship (Mandatory)
  • Experience in neutronics/reactor physics modeling and simulation (MCNP, OpenMC, or similar)
  • Proficiency in thermal and structural modeling and simulation
  • Strong Python programming skills for automating and coupling multiphysics tools
  • Genuine enthusiasm for continual learning and problem-solving

Extremely Desirable

  • Direct, hands-on experience with criticality experiments (Krusty, Godiva, Comet, etc.)

Highly Desirable

  • Familiarity with SNM, DU, Be/BeO, and other nuclear materials
  • Understanding of nuclear safeguards and proliferation protocols
  • Familiarity with NNSA procedures and documentation

Desirable

  • Experience with CAD/CAM tools
  • Hands-on fabrication: CNC machining, welding, assembly
  • Basic knowledge of electrical systems and power electronics

Who We're Looking For

You are an engineer who wants to build things — not just model them. You’re equally at home writing scripts to automate physics tools, designing a test assembly, or debugging a mechanical system. You enjoy working across domains, learning new skills, and applying your knowledge to meaningful real-world challenges.


Why Join Us

  • Work on high-impact advanced nuclear systems
  • Participate in experimental design and criticality R&D
  • Collaborate with a high-performance, interdisciplinary team
  • Competitive salary and benefits package
  • Opportunities for personal and professional growth
