Compact proton therapy systems for cancer treatment centers
Mevion manufactures gantry-mounted proton accelerators for radiation oncology, with a tech stack spanning industrial controls (VxWorks, ControlLogix, SolidWorks) and enterprise operations (Salesforce, Oracle, SAP, NetSuite). Hiring is accelerating across operations and engineering—a pattern that aligns with their active work on service scaling, supply-chain efficiency, and FDA/ISO 13485 compliance, indicating expansion beyond single-site installations toward multi-room facility deployments.
Mevion designs and manufactures proton therapy systems for cancer centers, operating from headquarters in Littleton, MA with international offices in the UK and Japan and a joint venture in China. The company's core product is the S250 Series—a line of modular proton therapy systems engineered around a patented gantry-mounted accelerator architecture and direct beam delivery. Mevion sells directly to hospital systems and cancer centers; the product portfolio ranges from single-room configurations to multi-room designs with redundancy. The organization spans 51–200 employees and is primarily focused on scaling service operations, improving manufacturing quality control, and managing the regulatory compliance burden inherent to Class III medical devices.
Mevion's stack includes VxWorks and ControlLogix for real-time control, C/C++ and Qt for software, SolidWorks for mechanical design, and enterprise systems (Salesforce, Oracle, SAP, NetSuite) for operations and supply chain.
