Senior Master Annotator

About the role

We are looking for a highly detail-oriented and technically strong Senior Master Annotator to define, maintain, and continuously improve annotation standards for robotic datasets. Various type of data sets can be generated which needs to be annotated and quality checked before they are put in production

What you'll do

• Define and maintain gold-standard annotations and benchmark (“gold set”) datasets for new and existing tasks
• Establish clear acceptance criteria, tolerance thresholds, and task-specific quality standards (e.g., frame-level tolerances)
• Develop, document, version-control, and continuously refine annotation guidelines and SOPs based on disagreement patterns and quality findings
• Design and implement Inter-Annotator Agreement (IAA) frameworks (e.g., Cohen’s/Fleiss’ kappa, tolerance-based agreement models) and produce regular quality reports
• Analyze disagreement trends, identify root causes, and recommend data-driven process improvements

What you need

• 4–7 yrs of experience
• Data annotation
• SOP writing
• Any graduate

Good to have

• Computer vision
• Python
