Graphic Design Expert - Canva Editor Experience Required

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.

You'll examine designs to understand color schemes, font choices, and other design elements. You will then review a slide within that design that seems out of place. Leveraging your graphic design expertise, along with what you learn in our training, you will edit the incorrect slide to match the rest of the overall design. This is all in an effort to train AI models that assess design effectiveness—contributing to cutting-edge technology that advances how AI understands and evaluates visual content quality.

• →Review designs in Canva Editor to examine various design 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
• →Identify flaws in one slide within the overall design. These flaws may be minor, like simple font size issues. They may be major, requiring a full reconstruction of the slide
• →Using the other slides in the design as reference, edit the flawed slide to build more cohesion across the entire design
• →Process high volumes of design samples with sustained attention to detail
• →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
• Fully proficient at intermediate to expert level in Canva Editor
• 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 your evaluation 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 re-calibration
• Minimum 20 hours per week availability for at least 4 weeks, with potential to extend

• 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 (branding, editorial, digital, UX/UI)
• Experience teaching or mentoring design concepts

• Experience with Canva Editor
• Prior data annotation, content moderation, or quality evaluation experience
• Exposure to machine learning or computer vision concepts
• Familiarity with design systems and component libraries

• High tolerance for repetitive evaluation tasks—finds rhythm and satisfaction in systematic work
• Ability to maintain consistent standards across thousands of ratings
• Strong pattern recognition—quickly identifying quality patterns across examples
• Disciplined, methodical approach with minimal variation in judgment
• Problem-solving mindset for handling ambiguous or borderline cases
• Interest in AI/ML applications in design and creative fields
• Previous remote work experience with self-directed tasks

You thrive on consistency and repetition - You find satisfaction in systematic work and can maintain quality standards while evaluating similar content repeatedly without losing focus or accuracy.

You have a calibrated design eye - You can quickly assess design quality against objective criteria and apply the same standards consistently across hundreds or thousands of examples.

You're objective and principled - You separate personal taste from professional assessment, basing ratings on established design principles rather than subjective preference.

You maintain sustained focus - You can work through high volumes of repetitive tasks while staying sharp and attentive to subtle quality differences.

You're a clear communicator - You flag confusing examples or rating criteria early, ask clarifying questions, and document edge cases clearly.

You're curious about technology - You're genuinely interested in how AI learns to evaluate design quality and see value in contributing to machine learning training data.
