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.About RayIntelligence
Radiotherapy clinics generate large amounts of clinical and operational data every day, but much of this information remains difficult to access, analyze, and act upon. RayIntelligence is designed specifically for radiotherapy clinics, bringing together data from treatment planning systems, oncology information systems, and other clinical and operational sources.
The platform enables clinics to analyze treatment workflows, patient volumes, machine utilization, resource planning, treatment patterns, and long-term outcomes. By making data more accessible and reliable, RayIntelligence helps clinics understand their operations, learn from past treatments, and continuously improve care.
For healthcare analytics to create value, clinics need confidence in the data they use. RayIntelligence ensures consistent metrics, understandable insights, and traceable data from source to result. Already deployed at customer sites, the platform is continuously expanding its analytical capabilities and adoption worldwide.
About the Role

Working in healthcare brings unique engineering challenges. Data quality, traceability, reproducibility, validation, and risk management are key aspects of our software development process. While RayIntelligence is not a medical device, we apply many of the same engineering principles and quality practices used across RaySearch.
Unlike internal analytics teams, we are building a product for environments where we do not control the source systems. This requires us to handle limited access to real-world customer data, variations between customer environments, and the challenge of creating analytics that clinics can understand and trust.
Today, the platform focuses on analytics and reporting use cases, with future AI and machine learning capabilities building on the foundations being developed. RaySearch supports the use of modern AI-assisted development tools where appropriate, while maintaining the quality standards and engineering rigor required in healthcare software.
Responsibilities
Capture and integrate data from clinical and operational source systems
Design, build, and maintain data ingestion and transformation pipelines
Develop analytical data models supporting product capabilities and customer use cases
Implement new analytics capabilities using and Python
Contribute to architecture and design decisions related to scalability, maintainability, and data quality
Improve observability, traceability, and reliability across the platform
Ensure that metrics, transformations, and data flows can be understood, tested, and verified
Participate in validation, testing, and risk-management activities appropriate for healthcare software environments

Technology Stack
Our platform includes technologies and programming languages such as:
Python &
Postgre & Server
dbt
AWS
CDC-based ingestion
Apache Superset

Your Profile 
We believe successful candidates will typically have experience in several of the following areas:
development
Python development

Description of Doctoral Candidate Project DC17

Radiotherapy is a fundamental modality in oncology treatment, typically delivered over multiple fractions across several weeks. Throughout the treatment course, patients may exhibit substantial anatomical modifications (such as tumour regression or weight loss) as well as biological and functional changes within both malignant and healthy tissues. These dynamic variations can compromise the precision and therapeutic efficacy of radiation delivery, making the initial treatment plan suboptimal and necessitating adaptive strategies to maintain clinical outcomes.

Current treatment planning and adaptation strategies in radiotherapy predominantly focus on the physical dose distribution delivered to the patient. While effective to some extent, these approaches offer limited personalization and frequently neglect individual biological variability, such as tumour response dynamics and normal tissue sensitivity.

This project seeks to enhance both the efficacy and personalization of radiotherapy by integrating biological modelling with conventional dose-based planning. Specifically, it will focus on developing methodologies that leverage biological information and imaging biomarkers for optimizing the initial treatment plan and guide adaptive strategies throughout the treatment course.

The project has three main components:

1. Robust radiobiological optimization – Improving initial treatment planning by considering not only dose but also radiobiological models that predicts how tumours and healthy tissues respond to radiation, while accounting for underlying uncertainties.
2. Functional imaging integration – Using advanced imaging (e.g., PET/fMRI combined with CT or other anatomical imaging) to monitor both anatomical changes and tissue responses, enabling adaptation of the radiotherapy treatment based on both anatomical and biological indicators.
3. Biologically guided adaptive planning – Combining these approaches into a research prototype of a commercial treatment planning system for individualised initial treatment planning and adaptive treatments, accounting for underlying geometrical and biological uncertainties.

By incorporating biological and imaging data, this project aims to enable more personalized and adaptive radiotherapy treatments, moving beyond traditional dose-based methods.

The successful candidate will be employed at RaySearch Laboratories under the supervision of Jakob Ödén and Albin Fredriksson and will join the Research Department, which currently comprises 29 members. The candidate will also be enrolled in the Ph.D. program in Medical Radiation Physics at Stockholm University and become part of its research group under the academic supervision of Prof. Iuliana Toma-Dasu. This unique collaboration offers a diverse and stimulating research environment, with access to offices and resources at both institutions, located in Hagastaden, Stockholm’s Life Science Hub, within walking distance of each other.

Your profile

Requirements:

• MSc who has excelled in a relevant field: applied mathematics, biomedical engineering, computer science, physics or similar discipline
• Knowledge and interest in programming and applied mathematics
• Excellent communication skills in English

Meriting:

• Experience in radiotherapy and/or functional imaging
• Experience in mathematical optimization and/or algorithms
• Programming skills in C# or C++

About the project: Advanced upright treatment planning

About 20 million patients are diagnosed with cancer each year, and this number is projected to reach about 30 million by 2040. Half of these receive radiation therapy as part of their treatment. Transitioning from a recumbent position, where the patient lies on a treatment couch, to upright treatments could provide both clinical and cost efficiency gains for these treatments and could help accommodate the increasing need for radiation therapy treatments.

The goal of this PhD project is to develop new mathematical methods and prototype software that will be used to perform research studies within the realm of upright radiotherapy. The project will involve mathematical optimization and computer science, as well as radiotherapy physics. Software development in languages such as C++, C# and Python will be an integral part of the project.

Three examples of possibilities and challenges posed by upright treatments are the following:

• For protons and light ions, a main topic is upright arc therapy, where the beam is delivered from a multitude of directions, preferably while the patient is rotated. Proton and light ion arc therapy in itself is an emerging field in radiation therapy, and the move to upright treatments is anticipated to facilitate the adoption of this type of treatments. Advancements on the accelerator side, such as multi-leaf collimated arcs and machines with fast energy switching can push this development forward, and versatile optimization algorithms for such accelerators have the potential to set a new state-of-the-art in ion treatments.
• For photons, the treatment machines have the potential to become even more compact and allow for faster collimation, and the possibility to translate the patient vertically while rotating opens for helical arcs. To reap the benefit of these new degrees of freedom, new optimization methods are needed.
• New uncertainties arising in upright positions, including challenges regarding patient positioning and organ motion, should be accounted for in the treatment planning process. Extension and use of the integrated algorithms for robust optimization in RayStation will be part of this research.

The PhD student will be affiliated with the Royal Institute of Technology (KTH) and follow the doctoral program in Applied and Computational Mathematics (KTH | Doctoral program). The department has around 30 active PhD students, which can serve as an additional network to the ones at RaySearch and the UPLIFT community. A Swedish PhD program normally runs over 4-5 years and the position is funded throughout this time. The PhD student will be employed by RaySearch with a competitive salary.

Within UPLIFT there will be continuous collaboration with other doctoral candidates, especially from GSI (Germany), CNAO (Italy) and Centre Léon Bérard (France), where the doctoral candidate will have longer or shorter secondments. A natural point of collaboration will include evaluation of the newly developed methods by retrospective planning on clinical patient cases.

Design with empathy. Build with purpose. At RaySearch, your UX work can touch lives in ways that truly matter.

About the role

Designing for oncology software means working in one of the most demanding and meaningful domains there is. You will be expected to make confident, well-reasoned design decisions that uphold safety, accessibility, and risk mitigation standards—working in collaboration with physicists and developers advancing the frontiers of cancer care.

As a UX Designer at RaySearch, you will be responsible for translating complex clinical needs into precise, user-centered, and empathetic interfaces. Working across product teams, you’ll design role-specific workflows, evolve our design system, and ensure that every detail holds up in the real world—where clarity, safety, and accessibility are critical.

This is a hands-on role focused on implementation, quality, and impact. You’ll design flows and UI components, collaborate closely with developers, and validate your work through usability testing. You’re expected to take initiative, follow through, and continuously improve the way we design—from the details in Figma (or whats next?) to the experience in the clinic.

You’ll be part of a collaborative UX team with service designers, clinical specialists, and engineers. Together, we make sure our tools don’t just work—but feel like someone cared enough to make them truly usable.

What you’ll do

• Design detailed user flows and high-fidelity UIs for complex clinical systems.
• Create and refine components based on our design system, adapted to real workflows.
• Prototype and test concepts early—ensuring they are intuitive, accessible, and safe.
• Collaborate with developers, product managers, and clinicians to deliver production-ready solutions.
• Take ownership of your work and have the ability to balance multiple constraints in complex design decisions.

What you bring

• 5+ years of experience in UX/UI design with a strong portfolio focused on implementation.
• Skilled in Figma and modern design systems; confident working close to code and developers.
• Curious about AI-enhanced design tools and how they can boost design quality and speed.
• Comfortable working in complex, data-driven environments—ideally healthcare or similar.
• Deep care for the people behind the interface—you obsess over clarity, empathy, and details.

Why this matters

We believe the future of UX in healthcare isn’t just about speed or automation—it’s about care. In a world where AI can generate anything, the difference is how it feels to the user. That invisible layer—how a product shows it cares—is what makes a lasting impact.

At RaySearch, we design tools that help clinicians focus on what matters the most: the patient. That’s our edge. And we’re looking for someone who shares that belief.
