As an AI Engineer on the platform side, you will build and operate the infrastructure that makes AI applications reliable in production: the data pipelines that feed them, the embedding and retrieval layers behind them, and the services, APIs, and monitoring around them.

Compensation

EUR 60,000–70,000 per annum

Responsibilities

Design, build, and operate the pipelines that power AI applications: document and data ingestion, chunking and embedding pipelines, vector stores, and retrieval services.
Productionize LLM-powered applications as reliable services: APIs, containerised deployments, observability, cost monitoring, and access control.
Integrate AI workloads with the data lakehouse platform — streaming (Kafka) and batch sources, query layers, and time-series stores.
Build and maintain evaluation, logging, and feedback infrastructure for AI applications in production.
Contribute to core data engineering duties: developing and maintaining data pipelines, ensuring data quality and reliability, and improving platform performance and efficiency.
