RaySearch develops software that supports cancer treatment at hospitals and radiotherapy clinics worldwide.
We are looking for a Senior Data Engineer to work on RayIntelligence, an oncology analytics platform helping radiotherapy clinics turn data into actionable insights.
Radiotherapy clinics generate large amounts of clinical and operational data every day. Much of this information remains difficult to access, analyze, and act upon. RayIntelligence is designed specifically for radiotherapy clinics and brings together data from treatment planning systems, oncology information systems, and other clinical and operational sources.
The platform supports everything from treatment workflow analysis, patient volumes, machine utilization, and resource planning to the analysis of treatment patterns and long-term patient outcomes. By making data more accessible and trustworthy, RayIntelligence enables clinics to better understand their operations, learn from past treatments, and continuously improve care.
For healthcare analytics to be useful, clinics need confidence in the data they are using. Metrics must be calculated consistently, results must be understandable, and the path from source data to displayed insight must be possible to verify. The platform is already deployed at customer sites, and we are now focused on expanding both its analytical capabilities and its adoption across clinics worldwide.
The role spans data ingestion, integration, transformation, analytical data modeling, and the implementation of new analytics use cases.
Working in healthcare brings unique engineering challenges. Data quality, traceability, reproducibility, validation, and risk management are important parts of how we develop software. While RayIntelligence is not a medical device, we apply many of the same engineering principles and quality practices used throughout RaySearch.
Unlike internal analytics teams, we are building a product for environments where we do not operate the source systems ourselves. Development must therefore account for limited access to real-world customer data, variation between customer environments, and the need to build analytics that clinics can understand and trust.
The platform currently focuses on analytics and reporting use cases, but future AI and machine learning capabilities are expected to build upon the foundations being developed today.
RaySearch supports the use of modern AI-assisted development tools where appropriate, while maintaining the quality standards and engineering rigor required in healthcare software development.
