Firma i stanowisko

EcoVadis is the leading provider of business sustainability ratings. Their solutions, backed by an international team of experts and advanced technology, analyze data and build sustainability scorecards to give companies actionable insights into environmental, social, and ethical risks in business.

Wymagania

Degree in Computer Science, Mathematics, Engineering, or related technical discipline.
4+ years of production experience with graph databases, specifically Labeled Property Graphs (such as Neo4j, Memgraph, TigerGraph) or RDF Triple Stores (GraphDB, Stardog, Virtuoso).
Strong experience in cloud technologies, preferably Azure and related ecosystem (Azure Foundry, Azure Bicep, AzureML, Azure Cloud Storage).
Advanced proficiency in Python (including RDFLib, NetworkX, PyGraphistry) for scalable, production-grade data pipelines.
Experience building entity extraction pipelines using modern NLP frameworks (LangChain, LlamaIndex, spaCy) or LLM-based structured extraction.
Hands-on experience with data transformation tools (dbt) and integrating graph databases with vector stores (Qdrant, Pinecone, pgvector) for hybrid search architectures.
Solid understanding of semantic web standards (RDF, RDFS, OWL, SKOS, SHACL, RDF-star, SPARQL) and graph schema design principles (T-Box vs. A-Box), plus mapping languages (RML, R2RML).

Nice to have:

Experience with domain-specific supply chain, carbon accounting (GHG Protocol), or lifecycle assessment (LCA) data.
Experience building Model Context Protocol (MCP) servers.
Experience with enterprise OBDA approaches at scale.

Obowiązki

Graph Infrastructure and Ingestion Pipelines:

Design, implement, and maintain high-speed GraphRAG ingestion pipelines transforming relational data, unstructured ESG reports, and streaming feeds into operational Labeled Property Graphs (e.g., Neo4j, Memgraph) and RDF Triple Stores.

A-Box Instantiation and Entity Resolution:

Build automated Named Entity Recognition (NER), entity linking, and deduplication workflows to unify vendor profiles, material SKUs, and facility coordinates into canonical graph nodes.

Semantic Federation and External Data Integration:

Implement automated ETL/ELT pipelines to map and federate internal supply chain data with external ontologies and registries such as GLEIF, W3C SSN/SOSA, Copernicus, and PROV-O.

GraphRAG and Agent Tooling:

Collaborate with AI/ML Engineers to build low-latency GraphRAG retrieval layers, write optimized Cypher and SPARQL queries, implement NL2Query tools for agents, hybrid vector-graph indexing pipelines, and Model Context Protocol (MCP) tool endpoints.

Deterministic Guardrails and Pipeline Validation:

Operationalize SHACL to create automated data quality tests within CI/CD pipelines to prevent hallucinated or non-compliant data mutations.

Performance Optimization and GraphOps:

Optimize multi-hop query performance, graph partitioning, and database indexing strategies for sub-second traversal over large-scale graphs.
