The future of AI — whether in training or evaluation, classical ML or agentic workflows — starts with high-quality data. At Human Signal, 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 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.

You’ll evaluate and rate graphic design elements on standardized quality scales to train AI models that assess design effectiveness—contributing to cutting‑edge technology that advances how AI understands and evaluates visual content quality.

• Review and rate graphic design elements using our Label Studio Enterprise platform across multiple quality dimensions:
  • Typography quality (readability, hierarchy, font pairing appropriateness)
  • Visual hierarchy effectiveness (clarity, balance, focal point strength)
  • Design element execution (icon quality, illustration polish, image selection)
  • Color palette effectiveness (harmony, contrast, accessibility)
  • Layout and composition quality (grid usage, spacing, alignment)
  • Overall design effectiveness and professional polish
• Apply consistent 1‑5 rating scales across hundreds of design examples
• Provide clear, objective assessments based on established design principles
• Follow detailed rating guidelines and rubrics to maintain consistency
• Process high volumes of design samples with sustained attention to detail
• Participate in weekly calibration sessions to align rating standards
• Meet quality benchmarks for rating consistency and inter‑rater reliability

• Formal training in graphic design, visual arts, or related field (degree, certificate, or bootcamp completion) OR 2‑3 years of professional graphic design experience
• Strong proficiency in design principles (composition, color theory, typography, visual hierarchy)
• Ability to objectively critique and evaluate design work against industry standards
• Understanding of what constitutes effective vs. ineffective design choices
• Experience reviewing or providing design feedback
• Exceptional attention to detail and ability to maintain focus during repetitive tasks

• Comfort with highly repetitive work—ability to maintain quality and engagement while rating similar content for extended periods
• Strong visual discrimination and consistent aesthetic judgment
• Reliability and consistency in applying rating standards
• Self‑motivated with ability to work independently on repetitive tasks
• Excellent focus and concentration for sustained periods
• Strong communication skills for flagging edge cases or unclear examples
• Comfortable with feedback and recalibration
• Minimum 10 hours per week availability for at least 3 months

• Portfolio demonstrating diverse design work and critical eye
• Experience as a design reviewer, art director, or in quality assurance roles
• Understanding of accessibility standards (WCAG, inclusive design principles)
• Knowledge of design across multiple contexts…
