Job description
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. You’ll collaborate closely with engineering and research teams to ensure data is labeled accurately, consistently, and to the highest quality standards.
What You’ll Do:

You’ll collaborate closely with engineering and research teams to ensure data is labeled accurately, consistently, and to the highest quality standards.
What You’ll Do:
- Manually annotate video sequences (boxes/masks/keypoints), track IDs, and label actions and temporal segments.
- Maintain data integrity by applying guidelines and QC checks; resolve ambiguities and fix errors.
- Leverage pre-annotation/autolabeling tools to boost throughput—validate/correct model prelabels and tune auto-tracking/segmentation pipelines.
Requirements
- 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
- 401k package
Commitment: This is a full-time, 2-month contract position staffed via HireArt with the possibility of extension. This position is onsite and available to candidates local to the Redwood City, CA area.
HireArt values diversity and is an Equal Opportunity Employer. We are interested in every qualified candidate who is eligible to work in the United States. Unfortunately, we are not able to sponsor visas or employ corp-to-corp.
