About the role

This is a remote, full-time consulting position (contract), responsible for designing, building, and maintaining the infrastructure required for relationship-centric data integration, storage, and advanced analytics.

We are seeking an experienced Graph Data Engineer to implement Google Cloud’s Unified Graph Fabric and strengthen a BigQuery-based "Customer 360" Knowledge Graph. The ideal candidate will move beyond traditional tabular reporting to analyze the "web of influence" within data, designing property graphs on BigQuery, implementing large-scale graph algorithms, and ensuring performant, cost-efficient graph queries, generating the corresponding pipelines that include AI.

Qualification & Experience

• Education: Must have a full-time Bachelor's degree in Computer Science, Data Engineering, or similar from a top-tier school.

• Experience: 8+ years of experience in data engineering roles, with 3+ years on Google Cloud Platform (GCP).

• Graph Expertise: Proven experience building production-grade data pipelines for use cases such as Identity Resolution, Knowledge Graph development, or Fraud Detection.

• Certifications: Google Cloud Professional Data Engineer certification is highly preferred.

Required skills/Competencies

• Core GCP Data Engineering: 8+ years of real-world development experience with expert knowledge of BigQuery (including Dremel engine) and Cloud Spanner.

• Graph Languages & SQL: Proficiency in GoogleSQL, including standard-compliant graph pattern matching (SQL/PGQ and ISO GQL), and writing complex relationship-traversal logic.

• Graph Architectures: Deep understanding of the trade-offs between Index-Free Adjacency (native graph stores) and Columnar Joins/Scans (BigQuery), and expertise in modeling using Adjacency Lists vs. Nested Fields.

• Python for Graphs: Expert knowledge in Python, specifically using BigQuery DataFrames (BigFrames), NetworkX, and GPU-accelerated backends like RAPIDS cuGraph.

• Orchestration & CI/CD: Strong experience with dbt (preferred) and Prefect or Apache Airflow (Cloud Composer) for orchestrating complex task flows.

• Data Governance: Good understanding of data governance frameworks, including experience with Data Catalog and lineage tracking for graph features.

Responsibilities:

• Graph Schema Implementation: Define and manage property graph schemas using declarative DDL (CREATE PROPERTY GRAPH) directly on existing relational tables and views in BigQuery and Cloud Spanner.

• Query Development & Feature Engineering: Build reusable graph-query patterns (multi-hop traversal, neighborhood signals) and feature engineering pipelines for "Customer 360" analytics, utilizing SQL/GQL and the GRAPH_TABLE operator.

• Global Analytics Execution: Implement and operationalize key graph algorithms: including PageRank, Community Detection, Shortest Path, and Centrality, using BigQuery DataFrames and native dispatching mechanisms.

• Pipeline Automation: Design and schedule automated transformation pipelines (ELT) to prepare "graph-ready" data and move insights from BigQuery back to operational layers (e.g., Spanner Graph) via Reverse ETL.

• Performance Optimization: Optimize query execution to avoid "referenced data" billing traps by implementing advanced partitioning, clustering, and cost-management strategies.

• Collaboration: Work with Product, Engineering, and Data Science teams to understand data requirements and deliver graph-derived features for downstream machine learning models.
