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's customer base is growing exponentially, and you will be on the front lines of ensuring that these customers become passionate, lifelong partners. As a member of our Customer Engagement team, you'll be accountable for establishing deep customer relationships, driving revenue, hitting SLAs, and maintaining the quality standards that power breakthrough AI applications. You will work closely with HumanSignal's enterprise customers and frontier labs, driving end-to-end engagements from new projects and pilots, owning account execution, working cross-functionally to ensure our Label Studio platform and Data Creation Laboratory services are delivered consistently and on-time, and driving account growth.
You are the primary contact between HumanSignal and our customers, working with and advocating for data leaders and engineering/operations teams who are pushing the boundaries of what's possible with AI. You have a strong interest in how purpose-built, human-created data can unlock novel AI capabilities. Your bias is towards finding not just one-off solutions, but repeatable and scalable ways to ensure we continually deliver excellence. You have a track record of managing customers to renewal, forecasting with precision, and supporting sales teams in driving expansion. And you are naturally empathetic and excel at building long-term relationships through diligent problem solving and thoughtful, strategic discussions. Within HumanSignal, you will work cross-functionally with Operations, Product, Sales, and our Data Creation Laboratory teams as the primary customer operations advocate.
The blend of operations and customer management to drive our most important outcomes makes this a unique and exciting role at the heart of HumanSignal's mission to harness human intelligence to power the future of AI. The ideal candidate is customer-driven, analytical, empathetic, outcome-focused, and above all someone who drives and inspires results.
