Nuclear Engineer, Fuel Cycle

The artificial intelligence industry is undergoing a critical evolution. As large language models grow increasingly sophisticated in processing and synthesizing highly technical literature across specialized scientific disciplines, major AI labs face a profound challenge: alignment and safety guardrails. While general software engineers can build architectures, they cannot discern the nuanced boundaries of complex scientific fields where safety tolerances, regulatory standards, and dual-use boundaries are exceptionally delicate. For elite nuclear engineers and fuel cycle practitioners, an unprecedented opportunity has emerged to apply professional domain knowledge directly to the future of artificial intelligence.

Mercor is actively building a specialized panel of nuclear materials and safeguards experts for the remote contractor role of Nuclear Engineer, Fuel Cycle. Offering a high-tier compensation rate of $65 to $75 per task, this flexible position empowers industry professionals to leverage their real-world background in enrichment, reprocessing, fabrication, and safety analysis to test and refine frontier AI safety models.

Whether you are seeking a lucrative remote side-consultancy, looking for complete schedule autonomy, or wanting to play a pivotal role in establishing safe AI boundaries, this comprehensive guide covers the position's core responsibilities, technical expectations, compensation perks (including unique referral and hourly bonus structures), and a step-by-step roadmap to successfully complete your application.

The Core Mission: Why Frontier AI Needs Nuclear Fuel Cycle Specialists

Large language models ingest millions of pages of scientific documentation, research papers, and technical specifications. However, raw ingestion does not equal safe contextual understanding. In the nuclear fuel cycle, the line between standard engineering utility and proliferation pathways is razor-thin. For instance, the exact material-balance calculations required to close an inspector's account can theoretically be manipulated to obscure inventory discrepancies; the exact processing steps utilized to fuel a commercial power reactor form the baseline of proliferation considerations.

An artificial intelligence model that unnecessarily refuses a routine, professional criticality-safety query is failing as severely as one that inappropriately answers a restricted prompt. Getting this boundary right requires specialists who have worked inside the fuel cycle—engineers who instinctively know which parameters represent routine industrial operations and which require rigorous scrutiny. This is the exact problem space you will address.

Your Day-to-Day Responsibilities:

• Drafting Targeted Prompts: Create intricate, single-turn prompts rooted in your specific nuclear engineering expertise, systematically categorized across three distinct levels: benign, dual-use, and adversarial.
• Evaluating Model Responses: Audit responses generated by AI models against defined policy standards, rendering precise, justifiable decisions on whether the system navigated the prompt correctly.
• Writing Reference Answers: Author the authoritative reference answer detailing what an accurate, safe response looks like, accompanied by the underlying technical reasoning.

Ideal Backgrounds and Qualifications

To ensure high-fidelity data, Mercor maintains rigorous vetting standards for its nuclear red-teaming panel. Ideal candidates possess hands-on professional experience, advanced academic training, or engineering credentials in sectors such as:

• Enrichment, Conversion, & Fuel Fabrication: Direct experience in process design, plant operations, facility throughput, and material handling.
• Reprocessing & Back-End Fuel Cycle: Specialization in chemical separations, high-level waste streams, and spent nuclear fuel management.
• Criticality Safety Engineering: Proven background in performing criticality safety evaluations (CSEs), establishing engineering limits and controls, and conducting accident analysis.
• Fuel Cycle Systems Analysis & Modeling: Expertise in mapping material flows, assessing cycle economics, and evaluating system performance.
• Safety Analysis & Licensing: Direct involvement in regulatory compliance, safety analysis reports, and facility licensing for nuclear fuel-cycle installations.

Beyond Technical Depth: The Demand for Rigorous Written Communication

This project is heavily writing-intensive. Technical mastery alone is not enough; every judgment, classification, and reference answer you submit must include a clear, cohesive written rationale that a non-specialist project supervisor can easily comprehend. Candidates with prior technical writing experience, peer-reviewed research publications, regulatory documentation background, or expert witness credentials hold a major competitive advantage.

Compensation Structure, Flexibility, and Growth Perks

Mercor provides an innovative, high-autonomy contracting ecosystem tailored for independent specialists seeking maximum flexibility without standard corporate overhead:

• Task-Based Earnings ($65–$75): Earn between $65 and $75 for every successfully completed evaluation task, giving you direct control over your income output.
• Performance Bonuses & Referral Incentives: Contractors benefit from transparent earning structures, including the opportunity to earn up to $250 for each successful professional referral you introduce to the platform.
• Complete Schedule Freedom: Work entirely on your own terms from any remote location, easily integrating tasks around your primary employment, research projects, or consulting schedule.
• Pacing and Comfort: Because evaluating complex safety scenarios requires intense concentration, experts are briefed beforehand and given full flexibility to pause or step away from tasks at any point without penalty.

Step-by-Step Guide to Completing Your Application Successfully

Because positions on high-level scientific red-teaming panels are exceptionally niche, spots fill up quickly. Follow these essential steps to maximize your chances of acceptance:

1. Highlight Specialized Experience: Tailor your resume or professional profile to clearly emphasize your hands-on background in fuel cycle engineering, enrichment, reprocessing, or criticality safety.
2. Include Writing Samples: Since the role demands precise, high-level written rationales, attach or link to relevant technical papers, reports, or documentation samples.
3. Complete Screening Promptly: Mercor has streamlined the hiring process down to efficient, single-interview workflows. Complete your assessment steps quickly to secure active placement.
