Colorado Springs, CO • On-site, Remote

$50 - $90/hr

Part-time

This job post has expired today. Applications are no longer accepted.

Job description

Role Title: Nuclear & Radiological Security Expert


Role Type: Contractor


Location: Remote


micro1 is engaging Nuclear & Radiological Security Experts to support a customer’s initiative focused on defining standards for nuclear-safety evaluations, information abstraction, and escalation protocols. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.


Scope of Work

  1. Define evaluation scope and standards for nuclear and radiological safety, nonproliferation, and security.
  2. Develop frameworks for safe abstraction of sensitive or classified information in technical contexts.
  3. Establish robust escalation thresholds and protocols for handling nuclear security risks in research and operational scenarios.
  4. Contribute expert guidance on benchmarking nuclear and radiological risk assessments, ensuring effective nonproliferation safeguards.
  5. Review, refine, and validate technical guidelines for nuclear/radiological safety in support of advanced-model training.
  6. Collaborate with multidisciplinary stakeholders to ensure safety standards protect national and global security interests while enabling legitimate scientific progress.
  7. Document best practices and decision rationales for information security and compliance in nuclear domains.


Preferred Qualifications

  1. 5+ years of relevant experience in nuclear physics, radiological safety, nonproliferation, or nuclear safeguards (ideally 8–20 years for senior contributors).
  2. Advanced degree, professional certification, or equivalent operational experience in nuclear or radiological domains.
  3. Proven background with government agencies, national laboratories, regulatory bodies, or academic research in nuclear security or policy.
  4. Thorough understanding of nonproliferation frameworks, international safeguards, and weapons-relevant controls.
  5. High credibility and recognition in nuclear or radiological safety communities.
  6. Exceptional written and verbal communication skills, with the ability to translate complex technical topics for diverse audiences.
  7. Experience contributing to or overseeing security evaluations, compliance protocols, or risk assessments within sensitive technical environments.
