"I am a software developer working on the oncology information system of the future - RayCare. Most of my time goes to hands-on work with both frontend and backend development of new features, though I can also be involved in planning and testing. We use the latest technologies to build our software, and I have gained a lot of new technical skills. I have also had the chance to work on integration projects with hospitals in the US. RaySearch is a company that offers great benefits and meaningful work. It is highly satisfying to use the power of technology to make a difference and save lives."

Abebe Hailu

System Developer

"With my background as an M.Sc. in computer graphics and scientific visualization, RaySearch is a place where I can use my knowledge, work within my area of expertise and help improve treatment for patients. By continuously improving our visualizations, we increase the physicists' and dosimetrists’ ability to plan, decrease the time it takes to understand RayStation, and improve the quality of treatments. Our goal is to convey complex information as efficiently as possible so that the radiation therapy staff can focus on their most important task: to produce the best quality treatment plans in the most efficient way."

Peter Asplund

System Developer

“With a background both as a scientist and as a system developer, RaySearch is a place where I can combine my interests. As a software developer I work closely together with physicists, usability designers and test engineers. Together, we work to create a product that is fast and reliable. It’s a great motivation to know that my work can help to improve the treatment of cancer, and what I do is important for the patients.”

Linnéa Skantz

System Developer

"The reason why I chose to study medical physics is that it is an interdisciplinary field where physics is combined with other disciplines, such as biology, in order to treat cancer. After having completed my MSc, I started my PhD in Medical Radiation Physics at Stockholm University. My PhD research was focused on radiotherapy with light ions, in particular the secondary dose deposition due to produced nuclear fragments. At RaySearch I’m working with the development of the treatment planning modules for protons and carbon ions in RayStation. Working at RaySearch means working in an exciting and research-intensive environment where highly competent people with different areas of expertise work together toward the goal of treating cancer."

Martha Hultqvist

Senior Physicist, Ph.D. in Medical Radiation Physics

"Since starting with RaySearch in early 2015, I have enjoyed working with such an exceptionally talented group of people. My main motivation in joining RaySearch was to be part of a company that is on the cutting edge of software development for cancer treatment. As an IT Specialist in the Service team at RaySearch, I work closely with clinics ensuring that their systems are performing at a high level at all times. We value developing relationships with our customers and ensuring that they are receiving the highest level of service. The enthusiasm that goes into making RayStation such an amazing product also makes RaySearch Laboratories a great place to work."

Meshan Naidu

IT specialist

"After finishing my PhD thesis in applied mathematics at Uppsala university, I started working at RaySearch as a research engineer in 2005. My area of expertise includes image analysis, image segmentation, applied geometry and image registration. During the last 10 years, I have had the opportunity to develop several algorithms and tools that are now used clinically, for example for patient modelling, at clinics all over the world. It feels very rewarding to know that my work contributes to the fight against cancer."

Ola Weistrand

Research Engineer

“I had the opportunity to start my time at RaySearch with my Master Thesis project, as part of my Engineering Physics education at KTH. Following that, I ran my own algorithm development project in collaboration with the RaySearch physics development group and a French hospital. This exciting project meant developing an algorithm for verifying that a cancer radiation therapy treatment has been performed correctly. Afterwards, I got offered  a physics research engineer position, a role in which I lead or take part in method studies and research collaborations involving all kinds of problem solving related to physics, math and programming. Much of my work is very research intensive and I get to work with competent people in a really nice work environment. I really enjoy that I get to learn new things on a daily basis, use all my physics knowledge from university, and contribute to a fascinating and important field of research, actively improving cancer treatment for patients all over the world.”

Rasmus Nilsson

Research Engineer

"As Director of Product Management for North America, my role is to capture customer enhancement requests, prioritizing them and providing clarification for the software engineering team in Sweden.  In essence, I am the voice of the US Customers, ensuring future software releases meet their clinical needs."

Dayna Bodensteiner

R.T. (R) (T), CMD. Director of Product Management- Americas

"Working at a dynamic and growing company like RaySearch is an exciting place to be. Our cutting edge treatment planning product, RayStation, has challenged me to learn more about the possibilities of computer planning for radiation therapy beyond what I did in the clinic to help better serve our customers. As an application specialist for Asia and the Pacific, I look forward to be a part of the expansion of the company into this very diverse region. Being at RaySearch has been a rewarding step in my career not only in my work, but for interactions with great colleagues and customers around the globe who make it what it is today."
