Principal AI Engineer (f/m/x)

• 10+ years of engineering experience, with deep hands-on experience delivering production LLM/AI application systems (multiple systems shipped and operated), or a strong retrieval, evaluation, model-infrastructure, search, or data-platform background with a demonstrated transition to production LLM delivery.
• Demonstrated depth in at least two of the following: permission-aware retrieval over enterprise data, evaluation methodology for LLM applications, model infrastructure or gateways at production scale, agent or workflow infrastructure, knowledge-graph construction.
• Production RAG experience: tuned, evaluated, and operated under real load, not just an out-of-the-box setup.
• Experience building auth-aware or permission-aware data systems of meaningful complexity.
• Architectural authorship, ADRs or equivalent that have survived scrutiny.
• Solid production cloud experience is required. AWS with Bedrock is strongly preferred, as the group standardises on AWS, Snowflake, and dbt.
• On-call experience for production AI or data systems.
• Strong written communication, comfortable producing ADRs and technical reviews.
• Current, hands-on coding fluency.
• Fluent written and verbal communication skills in English.

• Experience as the senior technical counterpart to a peer Data or Platform team.
• Hands-on experience with AWS, Snowflake, and dbt, or comparable infrastructure.
