Data Annotation Specialist

About the role

Saronic Technologies is seeking a Data Annotation Specialist to support its maritime autonomy programs. You will label and review visual datasets—images, video, infrared and other sensor data—to train machine‑learning models that enable autonomous operations at sea.

Key responsibilities

• Annotate and review large volumes of image, video, infrared, and other sensor data using computer‑vision labeling methods.
• Identify vessels, objects, environmental features, and other elements relevant to maritime autonomy.
• Maintain accuracy, consistency, and productivity across repetitive, detail‑heavy datasets.
• Apply evolving labeling guidelines and flag unclear edge cases.
• Perform manual annotation and quality review of auto‑labeled data as needed.
• Support priority project deadlines when required.

Required profile

• Prior experience in computer‑vision data annotation or labeling.
• Familiarity with annotation tools such as Labelbox, CVAT, or similar.
• Experience with segmentation masks, bounding boxes, key points, object tracking, or classification.
• Strong visual pattern recognition, spatial reasoning, and attention to detail.
• Comfortable with repetitive, process‑driven work while maintaining quality.
• Ability to adapt to changing priorities, labeling rules, and quality standards.
• Effective communication and teamwork skills.
• Basic understanding of maritime environments, autonomous systems, robotics, or defense technology is a plus.
