Polish Data Annotator, Remote (Full- or Part-Time)

About OpenTrain

OpenTrain is the #1 platform for finding and building careers in AI training and data labeling. We connect people with projects that shape how modern AI systems learn from human examples and help contributors grow skills and experience in this fast-growing field.

Why AI training matters

AI models learn from high-quality examples prepared and reviewed by people. Annotation work — from classifying text to verifying speech transcriptions — directly influences how systems understand language and behave in real-world use. This role gives you a hands-on way to contribute to cutting-edge AI while working remotely and flexibly.

The role

You will annotate and review Polish-language content across multiple data types (text, speech/audio, and images). Tasks include semantic classification, named-entity recognition, sentiment labels, and verifying speech transcriptions. Work is performed remotely as a contractor on a per-hour basis at $20 USD/hr.

This role requires strictly following project annotation guidelines and quality standards, reporting ambiguous or problematic data, and cooperating with the team on quality inspections and reviews. Labeling tools will be provided by the project (other/third-party annotation software).

• Employment type: Contractor (part-time available); full-time candidates expected to be available ~8 hours/day.
• Part-time minimum: 20 hours per week.
• Pay: $20 USD per hour.

What you'll do day-to-day

Complete assigned annotation tasks accurately and on schedule, submit results regularly, and respond to quality feedback. Promptly flag ambiguous rules, abnormal or low-quality data, and any issues that could affect annotation consistency.
