Data Annotation Contributor

The future of AI — whether in training or evaluation, classical ML or agentic workflows — starts with high-quality data.

At HumanSignal, we’re building the platform that powers the creation, curation, and evaluation of that data. From fine-tuning foundation models to validating agent behaviors in production, our tools are used by leading AI teams to ensure models are grounded in real-world signal, not noise.

Our open-source product, Label Studio, has become the de facto standard for labeling and evaluating data across modalities — from text and images to time series and agents-in-environments. With over 250,000 users and hundreds of millions of labeled samples, it’s the most widely adopted OSS solution for teams working on building AI systems.

Label Studio Enterprise builds on that traction with the security, collaboration, and scalability features needed to support mission-critical AI pipelines — powering everything from model training datasets to eval test sets to continuous feedback loops.We started before foundation models were mainstream, and we’re doubling down now that AI is eating the world. If you're excited to help leading AI teams build smarter, more accurate systems — we’d love to talk.

AI Data Collector — Turn the World Into Your Workplace!

About the Opportunity We’re building a global community of detail-oriented contributors who help improve the quality of datasets used to develop advanced technologies such as artificial intelligence and computer vision systems. As a Data Annotation Contributor, you’ll help review and refine labeled data to ensure accuracy and consistency. We are preparing for several upcoming initiatives and are inviting qualified contributors to join our growing community. By joining our contributor network, you’ll be among the first to hear about annotation projects that match your skills and location.

What You’ll Do Depending on the project, contributors may be asked to review and correct labeled data within images or videos. Tasks may include:

Reviewing and correcting bounding boxes around objects or people

Adjusting or refining segmentation or masking areas within images

Identifying and masking personally identifiable information (PII) when required

Ensuring annotations follow detailed project guidelines and quality standards

Flagging unclear or incorrect labels for review

Submitting completed annotation tasks through designated tools or platforms

Each project will include clear instructions, examples, and support from our team.

How Our Community Works Once you join our contributor community, you will:

Review project details and decide whether you’d like to participate

Complete annotation tasks that match your skills and availability

Gain access to future opportunities as new projects are launched

Participation is flexible, allowing contributors to select the projects they want to work on.

What We’re Looking For We’re looking for contributors who are:

Highly detail-oriented and focused on accuracy

Comfortable following structured guidelines and quality standards

Able to work independently and manage tasks responsibly

Strong communicators when questions or clarifications arise

Comfortable using online tools for reviewing or editing data

Previous experience with data annotation, image labeling, or quality review is helpful but not required. Training materials may be provided depending on the project.

Compensation Compensation will vary depending on the specific project and the country or region where the work is performed. Pay rates will be communicated prior to the start of each project and are designed to align with competitive rates for similar work in your location.

Why Join Our Contributor Community

Flexible opportunities to participate in data annotation projects

The ability to contribute to the development of emerging technologies

Access to a growing pipeline of global annotation initiatives

Clear instructions and support from experienced project teams

If you enjoy detail-oriented work and want to contribute to improving real-world datasets used in advanced technologies, we encourage you to apply and become part of our annotation contributor community.
