About

HireArt is helping our client find a Data Annotation Specialist to join its team.

In this role, you’ll help improve an AI system by annotating data across a variety of robot-performed tasks. Your work will directly influence the accuracy and efficiency of robotic arms.

What You’ll Do:

• Manually annotate video sequences (boxes/masks/keypoints), track IDs, and label actions and temporal segments.

• Associate’s degree or equivalent practical experience
• Strong attention to detail
• Consistent application of guidelines
• Ability to follow detailed instructions and work independently with minimal supervision
• Clear written communication and a collaborative attitude

Preferred Qualifications:

• Hands-on experience annotating video (boxes/masks/keypoints, action labels, ID tracking)
• Proficiency with annotation tools; comfort with pre-annotation/autolabel review and correction
• Familiarity with QA practices (inter-annotator agreement, spot checks, golden sets)
• Knowledge of common annotation formats (e.g., COCO, YOLO, MOT/KITTI) and basic video concepts (frame rate, codecs)

Perks & Benefits:

• Quarterly performance bonus program
• Catered meal during each shift and a stocked kitchen with snacks
• Potential for full-time conversion based on performance (e.g., data quality, speed, timeliness, and attendance)
• Pre-tax commuter benefits
• Employer (HireArt) subsidized healthcare benefits
• Flexible Spending Account for healthcare-related costs
• HireArt covers all costs for short- and long-term disability and life insurance
