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.
HumanSignal is looking for a high-performing Sales Development Representative to help us reach the world's most innovative AI companies.

- Demonstrated track record of top performance and consistently exceeding quota
- Exceptional written and verbal communication skills with ability to tailor messaging to technical audiences
- Research skills and intellectual curiosity to understand complex technical concepts quickly
- Ability to multitask, prioritize effectively, and thrive in a high-energy environment
- Experience prospecting into large, complex technical organizations
- Process-oriented mindset with strong organizational skills
- Resilience and persistence—you don't take "no" personally and you love the challenge of breaking into strategic accounts
Nice to Haves:
- Genuine interest in AI, machine learning, and emerging technologies
- Familiarity with how AI models are trained and the role of training data
