Annotator

We’re looking for a detail-oriented Annotator to support AI models that are reshaping how cancer patients receive treatment. This role focuses on reviewing and validating manually annotated data used to train large language models (LLMs). Your work will directly impact the accuracy and reliability of our machine learning systems.

This is a foundational role focused on high-precision annotation and quality control. Over time, there may be opportunities to take on broader responsibilities, including evaluating model outputs, but the core of the role remains hands-on quality assurance work.

• Examine Kaplan–Meier graphs and accurately mark specific clinical information according to defined guidelines.
• Ensure consistency, accuracy, and adherence to quality standards across large volumes of data.
• Identify issues in annotations and flag them appropriately to maintain high data quality.

Requirements

• Extremely detail-oriented and methodical.
• Comfortable performing repetitive, structured tasks with focus and consistency over extended periods.
• Able to follow precise guidelines and apply them consistently.
• Responsible, reliable, and quality-driven.

• Location: Tel Aviv (close to train and light rail)
• Work model: 4 days per week in the Tel Aviv office + 1 fixed work-from-home day
• Employment type: Full-time, global contract
• Compensation: 9,000 NIS per month + 1,000 NIS monthly Cibus (food allowance)
