ApplySend your resume to hiring@meitner.energy with the role in the subject line.The Opportunity
Meitner is hiring an Expert and Group Leader for the Licensing & Regulatory Affairs Department to lead licensing strategy, documentation, and regulator engagement for the ACR300. You'll own preparation, coordination, and submission of licensing documentation — from Construction Permits and Operating Licenses to Design Certifications and Environmental Impact Assessments.
As Group Leader, you'll consolidate inputs from neutronics, thermal-hydraulics, safety, mechanical, and I&C into coherent regulatory submissions, and represent Meitner in regulator audits, technical meetings, and RAI responses.
This role is ideal for someone who:
- Has 15+ years of in-house licensing experience leading interactions with national and international regulators
- Is comfortable both in technical depth and political/regulatory dialogue
- Sees licensing as a strategy discipline that shapes the project, not a paperwork function
- Wants to lead a discipline and a regulator engagement strategy at FOAK scale
What You'll Do
Licensing Documentation & Regulatory Strategy
- Lead preparation, coordination, and submission of licensing documentation for the ACR300 across design, construction, or operation phases
- Develop and execute regulatory engagement strategy to support project milestones
- Manage processes for Construction Permits, Operating Licenses, Design Certifications, Environmental Impact Assessments, and associated safety documentation
Regulator Engagement & Cross-Discipline Coordination
- Interface directly with regulatory authorities (NRC, ARN, ASN, NSSC, ONR, STUK) — audits, technical meetings, RAI responses
- Coordinate licensing inputs from multidisciplinary teams (neutronics, thermal-hydraulics, safety, mechanical, I&C) into coherent regulatory submissions
- Apply IAEA safety standards, INSAG guidelines, and national regulations (10 CFR, ARN norms, ENSREG, etc.)
Document Control & Team Leadership
- Manage licensing digital systems (LMS, EDMS, or national electronic regulatory platforms) — versioning, traceability, configuration control
- Represent the company in discussions with regulators, government agencies, and international organizations
- Lead and mentor junior engineers and regulatory specialists as Group Leader for the discipline
What We're Looking For
In-House Nuclear Licensing Leadership
- 15+ years of direct, in-house experience leading licensing activities in nuclear engineering organizations, with full involvement in regulator interactions
Regulatory Framework Depth
- Deep understanding of IAEA safety standards, INSAG guidelines, and national nuclear regulations (10 CFR, ARN norms, ENSREG, etc.)
- Direct interface experience with NRC, ARN, ASN, NSSC, ONR, STUK
Multidisciplinary Coordination
- Track record consolidating licensing inputs from neutronics, T-H, safety, mechanical, and I&C into coherent submissions
Qualifications
- University degree in Nuclear Engineering, Law, Public Policy, or related technical disciplines
- 15+ years of experience in nuclear licensing and regulatory affairs
- Preparation, coordination, and submission of licensing documentation for PWR reactors across design, construction, or operation phases
- Development and execution of regulatory engagement strategies to support project milestones
- Experience managing Construction Permits, Operating Licenses, Design Certifications, Environmental Impact Assessments, and associated safety documentation
- Deep understanding of IAEA safety standards, INSAG guidelines, and national regulations (10 CFR, ARN norms, ENSREG, etc.)
- Direct interface with regulatory authorities (NRC, ARN, ASN, NSSC, ONR, STUK), including audits, technical meetings, and RAI responses
- Track record coordinating licensing inputs from multidisciplinary teams into coherent regulatory submissions
- Strong communication and negotiation skills with regulators, government agencies, and international organizations
- Postgraduate specialization in nuclear law, regulatory systems, or safety assessments
- Familiarity with licensing digital systems (LMS, EDMS, national electronic regulatory platforms), document versioning, traceability, and configuration control

Why Join Meitner Energy?
Mission That Matters
You'll help bring clean, scalable nuclear power online — not as a future promise, but as an executable plan starting in 2030. The work you do here directly accelerates the global energy transition.
Real Ownership
Meitner is small enough that your decisions visibly shape the company — and ambitious enough that those decisions matter. We hire people who want to own outcomes, not just tasks.
World-Class Team Across Three Continents
Work alongside engineers, operators, and builders in Argentina, the US, and the UK who bring deep nuclear, industrial, and execution experience.
Execution Over Hype
The ACR300 is built on proven light water technology with targeted innovation — because deploying clean power at scale is an execution problem, not a science experiment. We value rigor, judgment, and follow-through.
