Sr. GCP Data Engineer (Remote)

Role Summary

Build the connectivity, profiling, and graph/search backbone that the ontology runs on — turning raw source systems into clean, lineage-tracked, query able knowledge.

Key Responsibilities

• Own data source connectivity: build and maintain adapters to connect master data and work-ticket APIs via BigQuery, Cloud SQL, REST/Apigee, GCS, and Pub/Sub.

• Own data profiling and inference: profile source data for quality, statistical patterns, dependencies, and lineage ahead of ontology mapping.

• Stand up and operate the Knowledge Core — the graph and search backbone — using Spanner Graph (or an equivalent property-graph/RDF platform), Dataplex, BigQuery, and Vector Search.

• Build batch and streaming ingestion pipelines that keep the graph and catalog current as source systems change.

• Implement data quality checks, schema discovery, and the metadata catalog, surfacing issues to the Architect and Data Domain SME.

• Capture and maintain data lineage from source system through ontology mapping to graph representation.

• Support the Architect's structural-ontology mapping by supplying profiled schemas, dependency maps, and sample data.

• Feed clean, well-profiled data to the ML/Applied Scientists for entity-matching and inference model development.

• Implement governance and control-plane requirements at the pipeline level: IAM scoping, encryption, and lineage tracking set by the Architect.

• Monitor pipeline health, performance, and cost across ingestion, profiling, and graph-load jobs.

Core Skills

• Source-system connectivity via BigQuery, Cloud SQL, REST/Apigee, GCS, and Pub/Sub adapters.

• Data profiling: quality assessment, pattern/dependency detection, and lineage capture.

• Graph and search backbone operations on Spanner Graph (or an equivalent property-graph/RDF platform), Dataplex, BigQuery, and Vector Search.

• Batch and streaming pipeline design (Dataflow, Composer, Pub/Sub).

• Metadata catalog and data-quality tooling.

• Pipeline-level governance: IAM scoping, encryption, and lineage instrumentation.

Required Qualifications

• 5+ years in data engineering, including building ingestion and metadata pipelines at scale.

• Strong Python and SQL.

• Hands-on experience with GCP data services: BigQuery, Dataflow, Pub/Sub, Composer, Cloud SQL, GCS.

• Experience with data profiling, lineage, and metadata catalog tooling (e.g., Dataplex or equivalent).

• Working familiarity with a property graph or RDF platform — Spanner Graph, Neo4j, Amazon Neptune, TigerGraph, JanusGraph, or an RDF/SPARQL store. Spanner Graph itself is not required; Cypher, Gremlin, or SPARQL query experience is an accepted equivalent and ramps up quickly.

Preferred Qualifications

• Direct hands-on experience with Spanner Graph specifically.

• Telecom OSS/BSS experience; TM Forum SID/eTOM familiarity.

• Apigee or another API gateway for source connectivity.

• GCP Data Engineer certification.
