About the job
The future of artificial intelligence—whether in training or evaluation, classical machine learning or agentic workflows—begins with high-quality data.
At HumanSignal, we are pioneering a platform that drives the creation, curation, and evaluation of that data. From fine-tuning foundational models to validating agent behaviors in real-world applications, our tools are utilized by leading AI teams to ensure models are based on genuine signals, not noise.
Our open-source product, Label Studio, has become the de facto standard for labeling and evaluating data across various modalities—ranging from text and images to time series and agents-in-environments. With over 250,000 users and hundreds of millions of labeled samples, it stands as the most widely adopted open-source solution for teams developing AI systems.
Label Studio Enterprise enhances this success with security, collaboration, and scalability features vital for supporting mission-critical AI pipelines—encompassing everything from model training datasets to evaluation test sets and continuous feedback loops. We initiated our journey before foundational models became mainstream, and we are amplifying our efforts now that AI is transforming the world. If you are passionate about empowering leading AI teams to build smarter, more accurate systems, we would love to connect.
