About AI training and this work

AI training (also called data labeling or human feedback work) is the human side of building AI — people prepare and review examples that models learn from. This project sits at the cutting edge of video understanding: your annotations will help benchmark and improve models that generate multi‑level captions for first‑person footage.

The role

We are recruiting experienced video annotators and QA/review specialists to perform dense annotations on egocentric (first‑person) video using OpenTrain. This is a contract, part‑time role expected to run at least 20+ hours per week during the pilot phase.

Compensation is USD $8 per hour. The pilot begins in February (availability needed for a pilot start on February 3) with a target completion date by the end of February; initial volume is 1000 hours with potential to scale up to 10,000 hours based on pilot performance. Target annotation accuracy is 95%+.

What you'll do

• Produce 3‑tier captions for egocentric videos: Tier 1 = 1–2 sentence high‑level summary (no timestamps).
• Improve pre‑annotated Tier 2 action segments: verify and refine start/end timestamps and write verb + object labels.
• Create Tier 3 trajectory annotations: sub‑second, body‑part‑level motion descriptions that may overlap and must be grounded in visible evidence only.
• Apply customer guidelines precisely: deliver accurate, complete descriptions and high timestamp precision to meet acceptance criteria.
• Work inside the OpenTrain platform to create and review labels and participate in QA workflows.

Requirements

• Confirm C1 English proficiency or higher: comfortable writing precise, natural descriptions.
• Prior experience with video annotation, especially action segmentation and temporal labeling.
• Proven ability to timestamp actions with tight start/end alignment; sub‑second precision preferred.
• Ability to write atomic, observable action labels in verb + object format (e.g., “grasp cup”).
• Experience writing trajectory/body‑part motion descriptions (e.g., left hand, right hand, torso) with <1s segments and overlaps.
• Familiarity with OpenTrain or equivalent annotation tools and ability to ramp quickly.
• Proven quality performance on similar projects targeting 95%+ accuracy and low rework.
• Availability to support the February pilot (pilot start Feb 3) and pass a short qualification check before starting.

Project details & schedule

Project name: Human Generated Egocentric Annotations (Action and Trajectory Level Annotations). The customer requests indicative quotes by January 30, 2026 for planning. The pilot phase is scheduled for February with a target completion by end of February.

Volume: pilot ~1000 hours of video with potential to scale to ~10,000 hours. Acceptance criteria focus on description accuracy, description completeness, and timestamp precision. Annotation tool: OpenTrain.

• Dataset: first‑person egocentric videos with multi‑tier captions (pre‑labeled data present for Tier 2).
• Label types: action recognition, tracking, and text generation (multi‑tier captions).
• Employment: contractor, part‑time; worldwide remote applicants accepted.

How to apply

To apply, submit your OpenTrain profile or application showing relevant video annotation experience, examples or portfolio links, confirmation of C1 English proficiency, and availability for a February 3 pilot start. Include any notes on expected annotation time per video hour and recommended resource counts for a 1000‑hour pilot and a scaled 10,000‑hour program.

• Include your indicative hourly rate (USD) — baseline rate for this posting is $8/hr as listed.
• List your experience with OpenTrain or equivalent tools and any past projects hitting 95%+ quality.
• Be prepared for a short qualification test and to follow detailed customer guidelines exactly.
