Your tasks:
Focus: Data pipelines and provisioning for NLP and LLM-based applications
• Combine classical data engineering with modern NLP approaches – particularly in the context of Large Language Models (LLMs), embeddings, knowledge graphs, Retrieval-Augmented Generation (RAG), and text-to-SQL applications
• Design, develop, and operate modern data architectures that form the foundation for advanced NLP applications – from knowledge management systems and semantic search solutions to RAG use cases
• Work closely with our clients to understand their business requirements and data processes, and translate them into tailored, scalable data and AI solutions
• Implement scalable data pipelines and infrastructures to efficiently provide, transform, and version large volumes of structured and unstructured data
• Ensure data quality, security, and governance along the entire value chain, and establish best practices for handling sensitive data in AI projects
• Build and operate scalable data infrastructures in cloud environments, and automate deployments and monitoring systems to ensure reliability and availability
• Provide strategic advice to clients and internal teams on data architecture, technologies, tools, and best practices, acting as a trusted advisor
• Support and mentor junior colleagues, share your knowledge within the team, and contribute to the development of statworx’s data engineering community through workshops, blog posts, or internal talks

Your profile:
• You hold a Master’s degree in (Business) Informatics, Computer Science, or a related field
• You have at least five years of relevant professional experience in data engineering or data architecture
• You have a strong understanding of modern data architectures (Data Lakes, Lakehouses, Data Warehouses) and are experienced in ETL/ELT processes and data modeling
• Ideally, you have experience building data infrastructures for NLP applications – especially in the context of LLMs, Retrieval-Augmented Generation (RAG), semantic layers, and knowledge graphs
• Hands-on experience with text-to-SQL systems or developing interfaces between natural language and databases is a plus
• You are experienced with cloud platforms (Azure, AWS, or GCP) and data platforms such as Databricks or Snowflake
• You are familiar with Infrastructure-as-Code (e.g., Terraform, Pulumi) and CI/CD workflows (e.g., GitHub Actions, GitLab CI, Azure DevOps)
• You have excellent programming skills in Python, SQL, and Bash/Shell, and you write clean, efficient, and maintainable code
• You understand the importance of data governance, security, and privacy (e.g., GDPR) and incorporate these principles into your architectural design
• You combine strong analytical thinking with the ability to translate business requirements into technical solutions and communicate effectively with stakeholders at all levels
• You are fluent in English (written and spoken) and have advanced German skills — or are willing to actively improve them

Our offer:
• Data & AI consulting as our core business: Work on exciting projects with leading clients – from cutting-edge NLP use cases to complex data science and machine learning solutions
• Depth and diversity: Engage with challenging, multifaceted problems and continuously expand your expertise in data science, machine learning, and AI
• Continuous development: We support your professional and personal growth through regular feedback, tailored learning opportunities, and our mentoring program
• Culture and collaboration: Experience an open, inclusive, and respectful working environment with flat hierarchies, short decision-making paths, and a strong sense of team spirit
