Radiant's goal is to bring one of the world's first factory-constructed microreactors to market.
The Role

Radiant is an El-Segundo, CA-based clean energy startup building a nuclear microreactor. A climate-friendly alternative to diesel generators, Radiant's Kaleidos 1MW microreactor will be the world's first portable, zero-emissions power source that works anywhere. We plan to test our development reactor by 2026 and if successful, it will be the first new commercial reactor design to achieve a fueled test in over 50 years. Radiant's goal is to bring one of the world's first factory-constructed microreactors to market. Our microreactor can bring power to remote parts of the world and provide backup power for life-saving applications in hospitals or disaster-relief scenarios.

  • Operate: independently drive execution. Recognize when to implement a quick fix and when to dive into the details. Create new processes and improve existing ones. Monitor performance.
  • Build: identify new opportunities. Own projects from ideation through execution. Identify gaps in our organization and fill them.
  • Analyze: solve problems from first principles. Leverage data, reports, and industry expertise. Disambiguate.

Required Skills and Qualifications:

  • Bachelor’s degree in Business Administration, Economics, Engineering, or a related field.
  • 3-7 years of relevant industry experience.
  • Proven track record of independent project execution.
  • Excellent analytical, organizational, and problem-solving skills.
  • Strong interpersonal and communication skills (written and verbal).

Desired Skills and Qualifications:

  • Experience at a fast-paced, high-growth startup
  • Experience at a hardware company, particularly within nuclear
  • Familiarity with operations in highly regulated industries

Additional Requirements:

  • Must be willing to work extended hours and weekends as necessary to accomplish our mission.
  • Must work 100% onsite at El Segundo HQ.
