Senior Data Platform Engineer

The Senior Data Platform Engineer builds the platform-services layer that turns the enterprise data platform into a product — API Gateway baseline, knowledge graph, event stream, semantic layer, data-product catalogue, vector search, anti-corruption-layer patterns, and the Python / TypeScript SDK framework that internal product teams consume. This is a senior software-engineering role focused on shipping platform capability with API contracts, SDKs, and governance baked in.

Key Responsibilities

• Design, build, and operate the platform API Gateway baseline — authentication, rate limiting, observability, versioning, contract tests, deprecation policy.
• Build and operate the Knowledge Graph platform — schema design, ingestion, query API, scaling, observability — exposed as a platform service to internal consumers.
• Build and operate the Event Stream platform — domain-event topology, partitioning, schema registry, retention; integrate with downstream catalogue and KG.
• Build and operate the Semantic Layer service — business-meaningful query API on top of the lakehouse, consumed by internal product teams and AI agents.
• Build and maintain the Data Product Catalogue — data-product registration, freshness SLOs, schema contracts, governance hooks at publish time.
• Build and operate the Vector Search Service infrastructure (pgvector, Milvus, Qdrant, or comparable) — index, scaling, observability — partnere
