Zusammenfassung

Digital Charging Solutions GmbH in Berlin/Munich seeks a Data Engineer to design, build, and optimize data architectures and ELT/ETL pipelines across charging, billing, invoicing, and promotions.

You will own the semantic layer, ensuring a single definition of revenue, margin, and active customers, and prepare data for AI-powered analytics and experiences. Strong SQL, Python, dbt, and cloud data warehouse experience are required.

Qualifikationen

• 5+ years of experience as a Data Engineer, ideally in large-scale transactional or subscription-based businesses (mobility, energy, fintech, or e-commerce a plus).
• Strong SQL (Snowflake, PostgreSQL) and hands-on experience with dbt or a similar transformation framework.
• Strong Python skills for data engineering, automation, and pipeline orchestration.
• Solid understanding of data modeling (star schema, large flat tables) and how models feed BI and semantic layers.
• Experience building or maintaining a semantic / metrics layer, and a genuine interest in making business data consumable by AI experiences.
• Familiarity with cloud data warehouses, APIs, orchestration (for example Airflow), and version control (Git).
• Comfortable applying software engineering practices: CI/CD, automated testing, code reviews, and monitoring.
• A genuine appetite to learn the business deeply and become a go-to reference on how the domain works, alongside your engineering craft.
• Strong communication and documentation skills, with the ability to work across technical and non-technical teams.
• Exposure to streaming technologies (Kafka, Azure Service Bus, Spark) and Azure cloud services.
• Infrastructure as code (Terraform, CloudFormation).
• Nice to have experience with AI and LLM tooling, RAG patterns, or vector stores applied to enterprise data.

Aufgaben

• Designing, developing, optimizing, and maintaining the data architecture and ELT/ETL pipelines across charging sessions, billing, invoicing, and promotions.
• Build and maintain large-scale batch and streaming pipelines, data warehouse models, and transformation layers.
• Own the semantic layer that defines consistent business metrics for revenue, margin, usage, and active customers.
• Prepare data so it is AI-ready for natural-language analytics and AI-assisted experiences.
• Understand the business domain to drive data modeling and exposure of data.
• Manage integrations between Snowflake, Power BI, SAP, APIs, and other analytics tools.
• Partner with analysts, data scientists, finance, and product to translate requirements into data solutions.
• Monitor, troubleshoot, and optimize infrastructure performance and cost.

Jobbeschreibung

Designing, developing, optimizing, and maintaining the data architecture and ELT/ETL pipelines that support our business goals across charging sessions, billing, invoicing, and promotions.

Build and maintain large-scale batch and streaming pipelines, data warehouse models, and transformation layers that are reliable, performant, and well documented.

Own the semantic layer that turns physical tables into governed business metrics, so that every team consumes one consistent definition of revenue, margin, usage, and active customers.

Prepare and structure data so it is AI ready, enabling natural-language analytics, retrieval, and AI-assisted experiences on top of a trusted foundation.

Become a master of the business domain, not only the data. Understand how charging, billing, settlement, invoicing, and OEM and fleet economics actually work, and let that knowledge drive how you model and expose the data.

Manage integrations between Snowflake, Power BI, SAP, APIs, and other analytics tools so the platform serves both reporting and operational needs.

Partner directly with analysts, data scientists, finance, and product to understand requirements, translate them into robust data solutions, and communicate the trade-offs back to stakeholders.

Monitor, troubleshoot, and continuously optimize infrastructure performance and cost.
