Senior Data Engineer (m/f/d)

Deine Aufgaben

Key responsibilities

• Design, implement, and operate scalable data pipelines for structured and unstructured data (batch and, where needed, streaming)
• Develop cloud-native architectures for data and AI workloads (primarily on Microsoft Azure)
• Build and evolve a materials data ecosystem linking physics-based modeling/simulation data and experimental laboratory data
• Handle large-scale scientific datasets (e.g., atomistic simulations, DFT/MD, high-throughput campaigns), including efficient storage, metadata, and performant access patterns
• Integrate data from HPC/simulation workflows and laboratory systems (instrument exports, LIMS/ELN where applicable) into curated, analysis-ready datasets
• Define and implement data models, metadata standards, and provenance to ensure traceability, reproducibility, and auditability across simulations and experiments
• Establish robust data quality practices (validation rules, unit consistency, schema controls) and data quality monitoring aligned with operational SLAs/SLOs
• Implement data governance foundations (cataloging, access control, lineage) and enable policy-driven data sharing across teams
• Enable production deployment of ML and NLP/LLMs/VLMs/VLAs etc. applications through strong MLOps/DataOps practices
• Integrate Azure OpenAI and LLM-based services into enterprise applications in a secure and maintainable way
• Implement Infrastructure-as-Code, CI/CD pipelines, and automation for data and AI systems
• Ensure reliability, security, GDPR compliance, monitoring/observability (logging, metrics, alerting), and cost efficiency of cloud platforms
• For LLM/RAG systems: manage embeddings and vector retrieval lifecycle, introduce evaluation and monitoring, and apply prompt/config versioning for repeatable releases
• Provide technical leadership through design reviews, documentation of standards, and mentoring where appropriate

Deine Qualifikation

Your profile
Education & experience

• Proven experience working with large-scale scientific datasets, ideally in simulation-heavy or R&D environments (materials, chemistry, physics, CAE, computational engineering)
• Experience designing or operating data ecosystems that unify multiple data domains (simulation + experiments) with strong governance and provenance

• Strong Python skills and experience with data processing frameworks
• Strong SQL skills and experience with data modeling for analytics and production use cases
• Proven experience with Microsoft Azure (Data Services, Compute, Storage, Azure OpenAI); AWS/GCP experience is also valued
• Solid understanding of DevOps/DataOps/MLOps practices, CI/CD pipelines, and automation
• Strong experience with containers (Kubernetes), Linux, Git, and system integration
• Familiarity with cloud databases, security concepts, and enterprise integration patterns
• Experience with orchestration tools and operational reliability practices
• Exposure to LLM workflows and RAG architectures; agentic AI experience is a strong plus
• Practical knowledge of distributed data processing and scaling patterns for ingestion/transform/query of very large datasets
• Bonus: familiarity with computational materials science/materials informatics, simulation pipelines, or lab data management (LIMS/ELN/instrumentation exports)

• Structured, pragmatic, and hands-on with strong ownership
• Able to communicate clearly across technical and non-technical stakeholders
• Curious about new technologies and able to translate them into reliable production systems
• Excellent communication skills in English; German is a plus
