Linac Development Engineer

View Ray Systems, Inc. is a private technology company seeking to provide the global radiation therapy community with advanced medical instruments incorporating the highest level of technology possible. Our belief is that only significant technological innovation can enable society to conquer disease. Our mission is to dare to change the paradigms of medicine and solve “impossible” technical problems to enable clinicians to effect a cure to save precious human lives, mitigate pain and suffering, and enhance quality of life.

Our vision is to become the world’s leader in producing highly effective innovative technology to cure cancer.

View Ray Systems designs, manufactures, and markets the MRIdian A3i® radiation therapy system to treat cancer patients with the smallest radiation therapy margins available with the highest patient throughput demonstrated for the most complicated cases. The system treats by aligning the sharpest radiation therapy beam on the market to diagnostic quality magnetic resonance images (MRIs) of the patient, adapts the treatment plan to the reality of the patient, and then uses the real-time MRIs to control the beam and record real-time doses delivered to the patient.

View Ray Systems is currently seeking a Linac Development Engineer, who will share our passion for conquering cancer and help us develop systems novel cancer therapy systems.
