Data Engineer – BigQuery & Platform Evolution

Responsibilities

• DWH & Data Modeling: You shape, build, and operate high-performing data warehouse structures and analytical models natively optimized for Google BigQuery. 
• SQL Transformations: Design, develop, test, and optimize complex, maintainable, and high-performance SQL-based data models using Dataform, dbt, or comparable transformation frameworks.
• Migration Projects: Contribute directly to the modernization of our data platform and drive the migration of existing data warehouse workloads from ClickHouse to BigQuery—including data models, transformations, pipelines, and validation.
• Data Pipelines & Semantic Layer: You engineer robust, fault-tolerant ingestion and ETL/ELT pipelines and model a consistent semantic data layer for reliable downstream data delivery. 
• Testing & Standards: Establish and continuously improve automated testing, data validation, and monitoring standards across all data pipelines.
• Software Best Practices: Apply modern software engineering practices—such as version control, code reviews, CI/CD, and automated testing—to elevate our data workflows.

Qualifications

• Experience: Professional experience (1+ years) in data engineering, data warehousing, or a similar role. You work highly independently and thrive when taking on real responsibility.
• Focus on SQL & Data: Strong SQL skills for crafting complex queries, modeling analytical layers, and handling large datasets with ease.
• Python & Automation: Practical experience using Python to implement pipelines, automate operational processes, and replace recurring manual tasks.
• Cloud & Tools: Sound hands-on experience with Google BigQuery in a production environment, as well as practical experience with Dataform or a comparable SQL transformation framework (e.g., dbt).
• Engineering Mindset: Solid foundation in Git-based workflows, CI/CD, and automated quality checks, paired with a pragmatic approach focused on reliability and maintainability.
• Language: German (B2 Minimum) and fluent English (written and spoken) for seamless collaboration in our international team.
