Validation Engineer - Context, Semantics & Memory (f/m/x)

You design and operate graph knowledges and graph databases that capture domain knowledge, toolchain topology, operational incidents, root cause analyses and lessons learned – enabling graph-based retrieval across the organization. Further, you context build-engineering pipeline that dynamically assemble, rank and budget the information supplied to LLM-based agents. So, you implement feedback loops: coding agents and skills that interact with our toolchain log outcomes, diagnose failures and write findings back into the knowledge graph, making the system progressively more capable. It is your responsibility to develop and maintain ontologies and semantic models for the automotive AI domain – sensor configurations, simulations, data-pipeline topology, model lineage – ensuring consistent vocabulary across teams and tools. You architect agent memory systems (working, episodic, semantic) with appropriate consolidation and retention mechanisms so that long-running agent sessions retain useful experience without context-window bloat. In addition, you evaluate and optimise retrieval quality using relevance, coverage, freshness and redundancy metrics, and run experiments comparing retrieval strategies (dense, sparse, graph, hybrid). You contribute to cost-efficient model selection and context-compression strategies (prompt compression, semantic caching, model routing) to keep latency low and budgets sustainable at scale.

University degree in Computer Science, Information Science, AI/ML, or a related field. 1-3 years of professional experience in knowledge management, knowledge-graph engineering or context engineering for AI/LLM systems. Expert-level programming skills in at least one high-level language (C++, Java, Kotlin or Python). Proficiency in AI-assisted development using coding agents search as Claude Code, GitHub Copilot or OpenCode. Hands-on experience building and querying graph knowledges (RDF/SPARQL or property graphs) and integrating them with LLM-based retrieval (e.g. GraphRAG, hybrid search). Experience with systems design, especially for knowledge-intensive or retrieval-heavy architectures. Familiarity with agent architecture memory, ontology design, semantic modelling, graph-based analytics, entity resolution or knowledge-graph embeddings. You enjoy working in an international team and are passionate about software quality?
