About the role
In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input.
Responsibilities
- Review video footage of robotic arms executing assigned tasks, identifying key actions and outcomes with precision.
- Apply detailed grading guidelines to accurately tag and annotate events, providing structured observations that improve model performance.
- Mark precise timestamps for the start and end of key actions, transitions, and outcomes, ensuring frame-accurate segmentation of each video session.
- Verify timestamp accuracy and alignment across annotations, correcting drift or inconsistencies between labeled events and the underlying footage.
- Utilize video annotation tools and platforms to record findings and submit annotated datasets in alignment with project standards and milestones.
- Collaborate with project trainers and contributors to resolve ambiguities, refine guidelines, and ensure annotation consistency across the team.
- Participate in ongoing quality reviews, incorporating feedback to maintain rigorous annotation standards.

- Analytical and problem-solving mindset, with a proactive approach to resolving annotation challenges.
Preferred skills
- Proven experience with video annotation, data labeling, or similar data-centric annotation projects.
- Familiarity with video annotation tools and software platforms, including timeline-based interfaces for timestamping and event segmentation.
- Experience with frame-level or timecode-based annotation (e.g., marking event boundaries, working with frame rates, or reviewing footage frame by frame).
- Background in AI training, machine learning data preparation, or robotics projects (strongly preferred).
