About the job
The future of artificial intelligence—whether it's in training or evaluation, traditional machine learning or autonomous workflows—begins with high-quality data.
At HumanSignal, we are developing the platform that facilitates the creation, curation, and assessment of that data. Our tools are utilized by leading AI teams to ensure models are based on real-world signals instead of noise, from fine-tuning foundational models to validating agent behaviors in production.
Our open-source product, Label Studio, has established itself as the de facto standard for labeling and evaluating data across various modalities—ranging from text and images to time series and agent-in-environment scenarios. With over 250,000 users and hundreds of millions of labeled samples, it stands as the most widely adopted open-source solution for teams building AI systems.
Label Studio Enterprise extends this success with the security, collaboration, and scalability features necessary for mission-critical AI pipelines—supporting everything from model training datasets to evaluation test sets and continuous feedback loops. We began our journey before foundational models gained popularity and are intensifying our efforts as AI continues to revolutionize the world. If you're eager to assist leading AI teams in developing smarter, more precise systems, we would love to connect.
HumanSignal is seeking a dynamic Sales Development Representative to help us engage with the most innovative AI companies globally. You will be instrumental in connecting with frontier labs, technology giants, and cutting-edge robotics firms that are shaping the future of AI and require the specialized training data that we provide.
This role transcends typical SDR responsibilities. You will prospect within organizations such as Anthropic, OpenAI, Google DeepMind, Meta, Tesla, Nvidia, and others at the forefront of AI research and development. Your outreach will target machine learning researchers, AI engineering leaders, and executives pioneering groundbreaking applications. The technical complexity and strategic significance of these accounts make this one of the most exciting SDR positions in enterprise technology.
You will serve as the initial point of contact for companies poised to define the next decade of technology. Your ability to craft persuasive messaging, grasp technical concepts, and engage senior executives will directly influence HumanSignal's growth trajectory.
