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

Human Signal is seeking a Quality Control Lead to ensure world‑class data quality across our Label Studio platform and Data Creation Laboratory operations. In this role, you will be the ultimate authority on the integrity and usefulness of the data we manufacture and deliver to customers. You will drive accountability across our highest‑impact projects—tackling complex quality challenges head‑on while leading strategic initiatives that enable reliable, scalable delivery as we grow.

Our Data Creation Laboratories don't just label existing data—we manufacture purpose‑built datasets from scratch in controlled environments. This means quality control takes on new dimensions: you're not just checking annotations, you're ensuring that the human‑generated data we create meets the exacting standards required by frontier AI labs and enterprises pushing the boundaries of what's possible.
