Senior Data Engineer

We are looking for a Senior Data Engineer to join an innovative project for a prominent European renewable energy company. In this role, you will help design and scale a cross-business anomaly detection solution (PoC) for complex industrial data. We need a senior-level, independent contributor with a strong engineering mindset who thrives in cross-functional environments and enjoys translating complex data into smart, reusable models.

Responsibilities:

• Design and implement streaming and batch data pipelines for data integration, ingestion, data quality management (quality gating), transformations, and auditing.
• Perform feature engineering and data exploration.
• Collaborate with business and operations teams to align on requirements, and to request and standardize waveform/sensor data.
• Build and maintain the Gold data layer, key KPIs, and PoC evaluation frameworks.
• Set up and maintain solid engineering practices, including CI/CD pipelines, Infrastructure as Code (IaC), version control (Git), unit and integration testing, and proper documentation.

Requirements

• Strong, hands-on experience with Azure and the Databricks platform.
• Solid experience with MLflow for lifecycle management.
• Proven track record in setting up production-ready engineering practices (CI/CD, IaC, Git, unit/integration testing).
• Senior-level engineering mindset with the ability to work independently in a complex data environment.
• Excellent communication skills and fluent English.

Will be a plus:

• Experience with Snowflake.
• Additional Data Science / ML capabilities, especially with anomaly detection (real-time or streaming scenarios).
• Experience with Databricks-based ML workflows, model serving endpoints, model versioning, testing, and tuning.
• Knowledge of statistical normalization techniques (e.g., z-score) and signal processing (e.g., FFT transformation).

What We Offer

• Direct cooperation with the already successful and growing project.
• Truly competitive salary.
• 20 days of paid vacation per year.
• Paid Polish public holidays.
• Private medical insurance package.
