The Role:

We are looking for Senior AI Data Engineers to implement and operationalize Comply’s semantic layer — turning the ontological models defined by our ontologist and architects into working knowledge graphs, vector search infrastructure, and LLM-powered pipelines. This is a hands-on engineering role at the intersection of knowledge representation, AI infrastructure, and data platform engineering. You will own the delivery of semantic layer components, collaborate closely with application and data engineering teams, and ensure that AI-ready data products are reliable, performant, and adopted in practice. You will report into the Data and Analytics organization as part of a new team being created to enable future data capabilities in relation to our AI ambitions.

Semantic Layer Implementation

Implement JSON-LD-based semantic models designed by the ontologist into production data systems

Build and maintain knowledge graph structures that reflect canonical domain models • Develop and manage graph database schemas, queries, and data ingestion pipelines

Ensure semantic consistency between ontology definitions and downstream data product

AI & Vector Infrastructure

Design and implement embedding pipelines that represent Comply’s financial and regulatory data in
vector space

Build and operate vector database infrastructure for semantic search and similarity retrieval

Implement RAG (Retrieval-Augmented Generation) architectures that ground LLM outputs in Comply’s
proprietary data

Evaluate and integrate LLM tooling and frameworks appropriate to Comply’s use cases

Data Pipeline & Platform Engineering

Build reliable, observable data pipelines that feed the semantic layer from upstream broker and
regulatory data sources

Apply DataOps practices including testing, monitoring, lineage tracking, and SLAs

Work with Data Engineers and Backend Engineers to embed semantic models into APIs and data contracts

Ensure the semantic layer scales with data volume and platform growth

Collaboration & Enablement

Partner closely with the Ontologist to ensure implemented models faithfully reflect domain intent

Support consuming application teams in understanding and adopting AI-ready data products

Contribute to resolving cross-domain data integration challenges

Strong hands-on experience in data engineering, with a focus on semantic or AI data infrastructure

Experience building and operating knowledge graphs or graph databases (e.g. Jena Fuseki, Neo4j, Amazon
Neptune, or equivalent)

Experience with vector databases and embedding pipelines (e.g. Pinecone, Weaviate, Qdrant, pgvector)

Practical experience implementing RAG architectures or LLM-integrated data pipelines

Familiarity with semantic web standards — JSON-LD, RDF, OWL, or SKOS

Strong Python skills and experience with data pipeline frameworks

Experience with cloud-native data platforms (AWS, Azure, or GCP)

Exposure to domain-driven design (DDD) and bounded contexts is desirable.

Experience working directly with ontologists or knowledge engineers is a plus.

Familiarity with data contracts and data product frameworks is a plus.

Experience with DataOps tooling, data reliability, or data observability platforms is desirable.

Background in financial services, RegTech, or compliance data is a plus.
