Data Modelling & Warehouse Engineer - healthcare data

Do you have a strong interest in data modeling and want to apply your skills in a domain that directly supports oncology workflows? At RaySearch, we are looking for someone who can help strengthen the data foundation behind our clinical analytics and machine learning efforts.

About RayIntelligence

RayIntelligence is a data platform for radiotherapy clinics, enabling advanced analytics and machine learning based on real-world clinical data. Our platform supports routine clinical operations as well as research and clinical trials, helping clinicians unlock insights that advance cancer care. We collaborate closely with leading clinics worldwide to develop impactful use cases that drive innovation in oncology.

About the position

In this position, you will contribute to a broad range of data engineering activities, extending beyond data modeling. A strong interest in the wider data engineering domain is therefore essential. At the same time, you will serve as a primary resource within the team for data modeling, supporting the development of best practices and strengthening the team’s overall capability in this area.

What you'll do

• Design and implement robust data models in dbt that enable clinical analytics, regulatory reporting, and machine learning use cases – working with datasets from:
  • RayCare (400+ tables)
  • RayStation (500+ tables)
  • Custom sources from partner clinics
• Shape and advance our data modeling methodology to support advanced analytics and regulatory reporting — evaluating and selecting the most suitable established approaches to ensure scalability, compliance, and long-term maintainability.
• Ensure data traceability, auditability, and accuracy to meet stringent regulatory requirements.
• Collaborate with a cross-functional team of engineers and clinical partners to co-develop impactful use cases.
• Mentor teammates in data modeling and warehousing best practices, raising the bar across the team.
• Over time, broaden your scope into areas like pipeline orchestration, performance optimization, or real-time data delivery — as the platform and your expertise evolve.

What we are looking for

• Deep understanding of how to model data to support analytics, compliance, and machine learning
• Experience in data engineering or data warehousing in complex environments
• Proficiency in SQL & Python
• Experience with dbt and modern ELT pipelines
