AI engineering roles in LLM evaluation, RAG, agent infrastructure, AI implementation and backend development: building systems where quality is measured, not assumed. Open to remote work, hybrid or on-site in the Netherlands, and relocation.

AI engineer building agent workflows, Python backends and RAG systems, and testing whether they're actually right.
What I'm looking for
I’m an AI engineer building Python backends, agent workflows and retrieval-augmented applications, with a focus on testing whether they work correctly.
SignalRank-RAG is my grounded Q&A service: hybrid retrieval, reranking and source provenance, deployed on Azure with authenticated APIs and an MCP server for AI agents. In SaaS Agent Lab, agents carry out policy-checked actions against a transactional backend, verified against database state with 700+ automated tests.
I also research AI reliability. In a controlled experiment involving six synthetic claims, withholding corrective evidence resulted in all six answers being wrong while each received a perfect RAGAS Faithfulness score. This is why I evaluate answer correctness alongside consistency with retrieved evidence.
Before AI engineering, I spent 12 years in scientific research at Leiden University Medical Center and the Institute of Cancer Research, designing experiments, analysing complex data and collaborating across disciplines.
I’m looking for opportunities in AI engineering, LLM evaluation, agent infrastructure and backend development. Based in Amsterdam; Dutch/EU citizen; open to remote work and relocation.
