About the Job

Requirements

  • Ability to design and develop scalable data integration solutions, from connecting heterogeneous sources to providing quality-assured data for applications, business units, and AI systems.
  • Ability to combine conventional and AI-supported data processing in hybrid ETL/ELT and data-fusion pipelines, including rule-based transformations, SQL, stream processing, model-based extraction, classification, and semantic enrichment.
  • Ability to work with structured, unstructured, and multimodal data, including business data, documents, images, audio, sensor data, and event data, and link related information through metadata, entities, and temporal and business relationships.
  • Ability to build data and knowledge pipelines for retrieval-augmented generation (RAG), including document preparation, chunking, embeddings, indexing, and retrieval components, while providing current, traceable information with appropriate access controls.
  • Ability to design suitable data and solution architectures by connecting cloud-based data platforms, lakehouse approaches, search and vector indexes, APIs, and potentially knowledge graphs, accounting for scalability, performance, security, maintainability, and cost-effectiveness.
  • Ability to prepare data pipelines for production operation, automate tests, deployment, and monitoring, and develop methods for data quality, versioning, traceability, and quality, runtime, cost, and failure handling of AI-supported processing steps.
  • Ability to work with platform, software, and AI engineering teams to evolve existing system landscapes, integrate new solutions into existing architectures, and support their transition to operations.
  • Ability to advise internal customers and project leads, combine technical and business perspectives, translate requirements into viable technical solutions, and coordinate business and technical dependencies with internal and external stakeholders.

Responsibilities

  • Develop the data foundations for analytics and AI products and design scalable data integration solutions, from connecting heterogeneous sources to providing quality-assured data for applications, business units, and AI systems.
  • Combine conventional and AI-supported data processing in hybrid ETL/ELT and data-fusion pipelines, selecting between deterministic methods and AI as appropriate.
  • Process structured, unstructured, and multimodal data, and connect related information through metadata, entities, and temporal and business relationships.
  • Build RAG data and knowledge pipelines, including document preparation, chunking, embeddings, indexing, and retrieval components, and provide current, traceable information while respecting access rights.
  • Design data and solution architectures by connecting cloud data platforms, lakehouse approaches, search and vector indexes, APIs, and potentially knowledge graphs, while considering scalability, performance, security, maintainability, and cost-effectiveness.
  • Make data pipelines production-ready and reliable to operate; automate testing, deployment, and monitoring; and develop methods to track data quality, versioning, traceability, and AI-processing quality, runtime, cost, and failure mechanisms.
  • Further develop existing system landscapes with platform, software, and AI engineering teams, integrate new solutions into existing architectures, and support their operational rollout.
  • Advise internal customers and project leads, translate requirements into viable technical solutions, and coordinate business and technical dependencies with internal and external stakeholders.
