Graphic Design Expert; International

Position: Graphic Design Expert (International) 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 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.Graphic Design ExpertLocation: RemoteType: Part-Time Contract (15+ hours per week for 2 weeks | 30 hour minimum commitment)Duration: 2 weeks with potential for ongoing workCompensation: Up to $20/hour for US based candidatesAbout the ProjectYou'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.What You'll DoReview 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 polishApply consistent 1-5 rating scales across hundreds of design examplesProvide clear, objective assessments based on established design principlesFollow detailed rating guidelines and rubrics to maintain consistencyProcess high volumes of design samples with sustained attention to detailParticipate in weekly calibration sessions to align rating standardsMeet quality benchmarks for rating consistency and inter-rater reliabilityRequired ExperienceFormal training in graphic design, visual arts, or related field (degree, certificate, or bootcamp completion) OR 2-3 years of professional graphic design experienceStrong proficiency in design principles (composition, color theory, typography, visual hierarchy)Ability to objectively critique and evaluate design work against industry standardsUnderstanding of what constitutes effective vs. ineffective design choicesExperience reviewing or providing design feedbackExceptional attention to detail and ability to maintain focus during repetitive tasksSkills & AttributesComfort with highly repetitive work —ability to maintain quality and engagement while rating similar content for extended periodsStrong visual discrimination and consistent aesthetic judgmentReliability and consistency in applying rating standardsSelf-motivated with ability to work independently on repetitive tasksExcellent focus and concentration for sustained periodsStrong communication skills for flagging edge cases or unclear examplesComfortable with feedback and recalibrationMinimum 10 hours per week availability for at least 3 monthsNice-to-Haves Preferred BackgroundPortfolio demonstrating diverse design work and critical eyeExperience as a design reviewer, art director, or in quality assurance rolesUnderstanding of accessibility standards (WCAG, inclusive design principles)Knowledge of design across multiple contexts (branding, editorial, digital, UX/UI)Experience teaching or mentoring design conceptsTe…
