As a Senior GCP Data Engineer , you will be the architect and builder of our data backbone.

What You’ll Do:

• Pipeline Architecture: Design, develop, and maintain high-performance batch and real-time data pipelines using Dataflow (Apache Beam), Cloud DataProc, and Cloud Pub/Sub.

• Data Modeling: Architect sophisticated data warehouses in BigQuery, utilizing partitioning, clustering, and optimized schema designs (Star/Snowflake) to ensure lightning-fast query performance.

• Infrastructure as Code (IaC): Manage and deploy cloud infrastructure using Terraform, ensuring environment consistency across Dev, Staging, and Production.

• Orchestration: Build and manage complex workflows using Cloud Composer (Apache Airflow) to ensure data integrity and timely delivery.

• Optimization & Governance: Monitor and optimize BigQuery costs and performance.

• Implement robust data governance, security, and IAM policies.

• Mentorship: Lead code reviews, define engineering standards, and mentor junior engineers on GCP-native patterns.

What we're looking for:

Must have:

• Cloud Platform - Expert-level knowledge of Google Cloud Platform (GCP).

• Languages - Mastery of Python and/or Java/Scala; Advanced SQL.

• Data Warehousing - Deep expertise in BigQuery (slots, reservations, BQML).

• Processing - Experience with Apache Beam, Spark, and Kafka. DevOps - CI/CD pipelines (GitHub Actions/GitLab), Docker, and Kubernetes (GKE).

• Demonstrable experience in data engineering, with at least 3 years focused specifically on the Google Cloud ecosystem.

• Mindset: A "security-first" approach to data and a passion for automation over manual intervention.

Nice to have:

• Transformation - Experience with dbt (data build tool) is highly preferred.

• Certification: Professional Google Cloud Data Engineer certification is a significant plus.

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related technical field.

Benefits:

• A competitive salary

• 25 days holiday plus bank holidays
