Dosimetry Manager

Role Overview

The Dosimetry Manager is accountable for the people, capacity, operational performance, clinical quality, and service delivery of their assigned dosimetry team, while supporting the financial performance and growth of assigned customer sites.

The role leads the day-to-day operation of dosimetry services, ensuring Lumonus has the appropriate resources and capabilities to consistently deliver safe, high-quality, efficient services to its customers. The Dosimetry Manager uses operational and clinical data to actively manage workforce capacity, productivity, quality, and individual performance and is accountable for identifying and addressing risks before they impact service delivery.

The Dosimetry Manager serves as the primary clinical operations escalation point for assigned customer sites, partnering with Customer Success, Account Management, Implementation, Product, and Technical Success. Customer Success retains ownership of the overall customer relationship. This is a leadership and management position focused on team outcomes rather than routine treatment planning.

• Maintain appropriate contingency and cross-coverage strategies to reduce reliance on individual team members and improve operational resilience.

• Address clinical service concerns, quality issues, staffing concerns, and performance issues within the manager's area of responsibility.
• Participate in regular reviews with Customer Success and Sales to understand site revenue targets, identify additional service needs and growth opportunities, and flag capacity or delivery risks early rather than absorbing unapproved work.
• Provide clear and timely clinical-service performance information to support customer reviews and escalations.
• Maintain productive relationships with clinical customer stakeholders while Customer Success, Account Management, and Commercial retain relationship, contractual, pricing, and revenue-target ownership.

1. Cross-Functional Partnership
