You will work closely with the materials experts simulation teams lab stakeholders and AI/ML colleagues to translate product goals into robust data products and production-ready solutions.
Key responsibilities
- Design implement and operate scalable data pipelines for structured and unstructured data including batch processing and event-driven or streaming workflows where needed.
- Develop cloud-native and on-premises 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
- Work with the DevOps team to implement and improve CI/CD pipelines deployment automation and infrastructure requirements for data and AI workloads.
- Ensure reliability security GDPR compliance monitoring/observability (logging metrics alerting) and cost efficiency of cloud platforms
- Provide technical leadership through design reviews documentation of standards and mentoring where appropriate
