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
This role is not for everyone.
We're looking for someone with a founder's mindset to lead our Columbus data collection facility — someone who gets energy from building something from scratch, isn't precious about job titles, and wants a front-row seat to the most consequential technological shift of our generation.
You'll manage daily operations, own project delivery, recruit talent, solve problems that don't have playbooks yet, and do a lot of things that aren't glamorous but are the core of running a real business. Coordinating schedules, chasing down compliance paperwork, building tracking systems, showing up when something breaks. If that sounds exhausting, this isn't the right fit. If that sounds like exactly where you learn the most — keep reading.
The upside is real. You'll work at the intersection of human intelligence and frontier AI, understand this space from the inside out, and grow fast in a company that's scaling quickly with major clients and a clear mission.
What You'll Do
Run the operation Lead day-to-day facility operations with full onsite presence during active projects. You'll own execution from setup to delivery — quality, timelines, logistics, and everything in between. When something goes sideways, you figure it out. You are the eyes and ears of onsite work and must be able to escalate appropriately when you need support with the norm being that you can create a solution.
Build the team Recruiting is a core part of this role. You'll develop pipelines, run outreach campaigns, build relationships with local universities and community organizations, and conduct screenings. You are the talent engine for Columbus.
Keep everything tight Meticulous documentation, scheduling, resource tracking, compliance, and reporting. This is the stuff that makes the difference between a facility that runs well and one that doesn't. You'll own it and take pride in it.
Bridge to HQ Coordinate with central teams on project planning, escalations, and resource needs. You're the face of HumanSignal in Columbus and the connective tissue between local operations and company-wide strategy.
What You Bring
You're technical enough to vibe-code your way through problems in Python (React experience is a plus), but your superpower is getting things done in the real world — not just in code. You've recruited and managed teams before, you know how to manage competing priorities without losing the details, and you operate well with minimal oversight. Extreme attention to detail and obsession with winning is a must.
Most importantly: you want to learn. You're drawn to hard problems and early-stage environments. You understand that the un-fun parts of a business are what make it work, and you don't look for someone else to handle them.
This role is 100% onsite during active project periods. This a requirement - this role is not open for remote work.
Compensation
We pay based on regional market rates. For this role, the base cash compensation range is $72,000–$90,000 USD. Final offers reflect your experience, expertise, and the scope of what you'll own.
