Director of Finance
About The Position
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. About the Role We’re hiring a Director of Finance to own the financial backbone of HumanSignal, the company behind Label Studio. Reporting directly to the CEO, you’ll own financial planning, business analytics, and the metrics infrastructure that drives decision-making across the company, including our SaaS & labeling services business. This is a hands-on leadership role with broad scope. You’ll partner with the executive team on strategy and planning, work cross-functionally with product, marketing, and sales, and build the financial infrastructure we need for the next stage of growth. If you’re energized by ownership, building from scratch, and operating at the intersection of strategy and execution, this is your role.
