Senior Data Platform Engineer Role Summary We are seeking a Senior Data Platform Engineer to help build, scale, and operate our bespoke enterprise data platform, the foundational infrastructure layer that ingestion, ontology, and business application teams build on top of. This is a hands-on, individual-contributor role for someone who wants deep technical ownership of platform internals rather than owning specific business data pipelines: our platform stack spans Airflow, Iceberg, Spark, Flink, Kafka, Nessie, Trino, and StarRocks, along with supporting UI components for platform users. You will not own the business logic of individual data pipelines; those are owned by application and business teams. Instead, you will build and harden the core platform capabilities that make those pipelines possible: ingestion frameworks, data cleansing/harmonization utilities, storage and compute infrastructure, and the APIs and agentic (MCP) interfaces that let both humans and AI agents access and operate on platform data and capabilities. You'll also be expected to bring an agentic software development approach to your own work, using AI coding agents and tooling to meaningfully multiply your engineering throughput, not just as an experiment on the side.

Platform Capability Engineering Design, build, and operate core platform capabilities on top of Airflow, Spark, and Flink for batch and streaming data processing, providing reusable frameworks that application/business teams use to build their own pipelines rather than building pipelines on their behalf. Own the data lakehouse layer built on Iceberg, Nessie (catalog/versioning), Trino, and StarRocks, including table format management, catalog governance, query performance, and storage lifecycle (compaction, partitioning, retention). Build and maintain Kafka-based streaming infrastructure (topics, schema management, connectors) that supports both platform-internal needs and consumption by downstream teams. Develop reusable ingestion, cleansing, and harmonization frameworks/libraries that application teams can adopt to bring data onto the platform in a consistent, quality-controlled way, without the platform team owning each pipeline's business logic. Build and maintain UI components that give platform users (engineers, analysts, business teams) visibility into platform state, data catalogs, job status, and data quality. API & Agentic (MCP) Enablement Design and build APIs that expose platform data and capabilities (ingestion, querying, catalog metadata, job orchestration) to downstream teams and services in a well-governed, secure, and performant way. Build and maintain MCP (Model Context Protocol) servers/interfaces that expose platform data, catalogs, and lineage to AI agents and LLM-based tools, enabling agentic consumption of platform capabilities. Extend agentic enablement beyond data access by building the tooling and guardrails that allow AI agents to safely operate parts of the platform itself (e.g., triggering pipeline runs, querying job status, remediation actions), with appropriate human-in-the-loop controls where needed. Partner with platform consumers (including the Ontology Platform team) to understand their API/agentic access needs and translate them into platform capability requirements. Scalability & Resilience Ensure the platform scales reliably as data volume, source count, and consumer count grow, through capacity planning, performance tuning, and architectural evolution across the
