Medical Image Annotation Supervisor

Primary Function of Position We are seeking a Medical Image Annotation Supervisor to support Ion’s Machine Learning Engineering team. In this role, you will oversee a team of annotation technicians working with CT, MRI, ultrasound, and bronchoscopy images to support the development of state-of-the-art image-guided robotic systems. You will create high-quality ground truth datasets for medical imaging algorithms using manual and semi-automated segmentation tools while also ensuring the team meets its quality and productivity goals. This role requires strong attention to detail, a focus on accuracy and consistency, and the ability to coordinate as the primary point of contact for the annotation team. The ideal candidate brings several years of hands-on experience in medical imaging or data annotation, and is ready to take the next step into a supervisory capacity. Formal people management experience is not required, but a demonstrated ability to communicate with, guide, support, and quality-check the work of peers is essential. As a bilingual supervisor based in Mexicali, you will play a critical role in bridging communication between the local annotation team and U.S.-based engineering stakeholders. You must be comfortable working in both English and Spanish across written documentation, verbal communication, and technical instruction. Occasional travel to U.S. facilities will be required for training sessions, meetings, and cross-site collaboration, and candidates must hold a valid passport and U.S. visa or be eligible and willing to obtain one prior to the start date. Essential Job Duties The Medical Image Annotation Supervisor plays a central role in ensuring the quality, consistency, and timely delivery of annotated medical imaging datasets that directly support the development of Ion's image-guided robotic systems.
