Workplace: hybrid

Department: Technology

Description

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 - partnered with AI engineering on embedding model selection and retrieval relevance.
• Author and maintain the Anti-Corruption-Layer Patterns Library - reusable patterns for legacy system integration (Oracle, SAP, WMS) via events and ACL only; never direct DB writes.
• Build and maintain the Python and TypeScript SDK framework - consumed by product teams and AI engineering for all platform-service calls.

Requirements

• Bachelor's or Master's degree in Computer Science, Engineering, or a related discipline.
• 8+ years software engineering with production ownership of platform services at multi-team scale.
• Strong Python (production services, async, observability) and TypeScript at senior level.
• API-first design discipline - OpenAPI 3.1, REST, gRPC; versioning, semver, deprecation policies, contract tests.
• Production experience with at least one of: knowledge graphs (Neo4j, Neptune, TigerGraph), event streaming (Kafka, Event Hubs), or vector databases (pgvector, Milvus, Qdrant).
• Distributed systems fundamentals - concurrency, message queues, idempotency, observability, performance.
• SDK / client library design for multi-language consumption; semver, breaking-change policy, documentation discipline.
• Cloud + Databricks (or equivalent lakehouse) production experience; Azure preferred.

Preferred

Qualifications

• Production knowledge-graph experience at scale (multi-million entities); semantic layer / data products in production.
• Multi-language SDK design across Python and TypeScript / Java; OSS library maintenance.
• Retail / commerce data integration - Oracle (RMS, RPM, PMS, SIM), SAP, WMS; strangler-fig patterns.
• Vendor certifications such as Databricks Data Engineer Professional, Azure Solutions Architect, or comparable.
