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. ## About the Opportunity We're looking for graphic design professionals to rate the quality of design work, helping AI models learn what makes a design effective. ## Key Details - Type: Freelance, project-based opportunity - Project length: 6 weeks, with new projects launching regularly - Compensation: Paid per accepted task.

You’ll rate and edit the samples we provide, following our guidelines. ## What We're Looking For Must-haves - Education in design or arts (degree or certificate) - 2+ years of experience as a graphic designer, SMM specialist, or marketing professional - Strong grasp of composition, color theory, typography, visual hierarchy, and overall design effectiveness - Exceptional attention to detail and ability to maintain focus during repetitive tasks - Openness to feedback and recalibration ## Nice to have - Design review, art direction or QA experience, with the ability to critique design objectively against industry standards - Experience with Figma, Sketch, or other modern design tools - Prior data annotation or AI training experience How It Works - Apply - Register on our platform - Confirm your identity - Validate your skills - Start earning on projects ## Why Join Us - Work from anywhere: fully remote, with just a laptop and a stable internet connection. - Set your own schedule: work whenever suits you, alongside your current job, studies, or other commitments. - Get paid every week: weekly payouts for the work you deliver. - Shape the future of AI: your expertise helps train the AI tools people use every day. - More projects ahead: once you're validated, get access to new projects that match your skills. ## About HumanSignal ## Company Overview - **One-liner**: HumanSignal provides an open-source and enterprise data labeling platform that enables AI teams to build high-quality datasets, evaluate models, and scale human judgment for machine learning. - **Entity Type**: Private (startup; $30M total funding raised from venture investors) - **Headquarters**: San Francisco, California, United States - **Founded**: 2019 - **Founders**: Not publicly named on the website, but described as a team of Data Scientists and ML Engineers who met on a Himalayan expedition. ## Core Business - Primary industry: Data labeling, AI training data, machine learning operations (MLOps), data-centric AI infrastructure. - Target customers: B2B – data science teams at enterprises, AI startups, and organizations building custom ML/AI models (e.g., Bombora, Zendesk, Outreach, Trivago, Wyze). - Mission: “To advance data-centric AI” and “help data scientists use data to teach ML/AI models how to make the best predictions.” ## Products & Services - **[Label Studio (Open Source)](https://humansignal.com/)**: The most popular open-source data labeling platform, used by over 1,000,000 AI practitioners.
