About Meitner Energy
Meitner Energy is developing advanced nuclear energy solutions intended to deliver reliable, scalable, and carbon-free electricity for industrial and grid applications.
Our international team brings together nuclear, engineering, commercial, regulatory, and project-development experience. We are building an organization focused on disciplined engineering, responsible execution, and the deployment of nuclear energy at meaningful scale.

The Opportunity
Meitner’s AI platform is only as useful as the retrieval layer beneath it, and this role owns that layer end to end. You will build the ingestion pipeline that processes a large corpus of regulatory and engineering documents, implement the hybrid retrieval and reranking stack that surfaces the right passage from the right document, and maintain the evaluation set that tells you whether retrieval is actually improving. The corpus includes scanned engineering drawings, technical standards, and regulatory material across multiple jurisdictions,



so the parsing and optical character recognition problems are substantial and real.
Because the corpus contains export-controlled and otherwise sensitive material, every retrieval decision carries an access-control dimension. Access enforcement happens before retrieval rather than as a filter applied afterward, and citations must trace back to the source document and page. You will own the retrieval quality metric, the evaluation set behind it, and the pipeline that keeps both current as the corpus and the models change.
This role is idóneo for someone who:
• Treats retrieval quality as a first-class engineering problem rather than a setting to configure once and forget.
• Has worked with messy real-world document corpora, including scanned files, mixed formats, and inconsistent metadata, and knows what making them searchable actually costs.
• Builds evaluation into the work rather than adding it after someone complains about a bad answer.
• Is energized by comb
