Real-world data is the competitive edge in AI.
HumanSignal is a human data partner for companies building AI models and products. Our customers ship better AI, faster, because we partner with their researchers from real-world data creation to annotation to delivery.
We design and create datasets from scratch, recruit and manage the domain experts who evaluate model output, and run everything through our own platform, Label Studio, the open-source standard for data labeling and evaluation, used by over 1 million practitioners worldwide.
We specialize in the operationally complex: real-world data collection, multimodal pipelines, and multi-step workflows. Advanced ML and AI teams use our enterprise platform to run their own data factories, and our services team to extend their reach where in-house capacity runs out.
If you want to do work that materially shapes how the next generation of AI products gets built, we'd love to talk.
You'll join a small marketing team at a fast-moving AI startup where you'll be exposed to a broad range of marketing disciplines and have autonomy to get things done. One day you're editing a launch video, the next you're staging an email campaign or planning a happy hour at a conference. You'll get real ownership, direct mentorship, and room to explore which part of marketing fits you: content, events, demand generation, community, or something you discover along the way.
We expect you to work with AI at every step. You'll use tools like Claude to draft, research, edit, and automate, and you'll help us create and hone new AI workflows the rest of the team adopts.
Send us your resume plus one thing you've made that you're proud of: a video, a post, a campaign, a meme that went further than you expected.
After you apply, unlock the direct contact details of the people who actually make the call. A quick follow-up makes you 5x more likely to land an interview.
