About this role

Our client is looking for a Senior Data Engineer to design, scale, and maintain high-performance ingestion, Change Data Capture (CDC), and delivery pipelines. In this role, you will architect enterprise-grade data platforms to process large-scale metadata, algorithmic feature extraction, and licensable asset datasets. This team sits at the foundation of the data processing and feature enrichment pipelines. Driving consistency and performance across an ever-growing data lake, we provide guardrails and sound system design patterns to inform the creation and fine-tuning of the industry's cutting-edge foundational large language models.

You will leverage Google Cloud Platform (GCP) as the primary compute foundation of a multi-cloud data processing ecosystem, alongside hybrid data warehouses and query engines including Snowflake and ClickHouse to provide low-latency data exposure, incremental delta tracking, and seamless integration endpoints for downstream AI/ML consumption. Primary Tech Stack: GCP, ClickHouse, Snowflake, dbt Core, Apache Airflow, Python, SQL.

Responsibilities 1. Ingestion Architecture & GCP Foundation: - Architect, build, and optimize scalable job creation, batching, and high-throughput ingestion pipelines hosted on GCP. - Implement serverless and containerized data pipelines using GCP infrastructure (BigQuery, Dataflow, Pub/Sub, Cloud Storage, GKE). 2. Enterprise ETL, CDC & Incremental Processing: - Design robust Change Data Capture (CDC) and incremental update workflows to enable fast delta synchronization across platforms.

- Build dbt transformation models and Airflow orchestrations following Data Vault / dimensional modeling patterns. - Implement delta tracking methods (e.g., hash keys, hash diffs) to track row-level asset modifications and metadata events. 3. Multi-Engine Analytics & Query Optimization: - Maintain and optimize Snowflake integration layers, handling deduplication logic, canonical content filtering, and policy restrictions.

- Deploy and manage ClickHouse as a high-concurrency analytical engine to deliver sub-second metadata retrieval and indexing. - Construct dedicated integration views and API query layers allowing internal and external clients to consume real-time delta updates. 4. Data Quality, Governance & Scalability: - Enforce metadata schema standardization, canonical asset mapping, and automated validation layers across diverse asset types (images, video, 3D models, audio).
