Remote | Senior Product Designer & AI Prototyping Expert — $60–$70/hour

24-MAG LLC connects experienced professionals with remote consulting opportunities across technical, evaluation, and project-based workstreams. The Senior Product Designer and AI Prototyping Expert will create and evaluate product design, UX/UI, design-system, usability, and AI-assisted development scenarios, prototypes, reference outputs, and expert-level evaluation rubrics.

Responsibilities:

• Develop realistic evaluation scenarios involving product design, UX/UI workflows, and visual design systems
• Create tasks covering interaction design, user journeys, component systems, and product experience
• Apply human-centred design principles and professional design judgement to complex product scenarios
• Produce reference design specifications, prototypes, and usability evaluation materials
• Assess whether proposed solutions meet appropriate standards for usability, consistency, and design quality
• Create tasks involving natural-language-driven software development and rapid prototyping
• Develop realistic workflows using AI coding assistants and AI-native development tools
• Apply iterative prompt-driven development approaches to prototype applications and product experiences
• Produce reference prototypes, code artefacts, and implementation examples where appropriate
• Evaluate how effectively AI-assisted workflows translate product requirements into functional software
• Develop scenarios involving scalable design systems and reusable component libraries
• Evaluate consistency across interaction patterns, visual systems, and product interfaces
• Create tasks reflecting real-world design-system governance and implementation challenges
• Assess collaboration between design and engineering when translating design systems into production
• Apply senior-level judgement to component architecture, documentation, and design consistency
• Develop scenarios involving user research, usability testing, and product validation
• Create structured evaluation tasks based on user feedback and behavioural insights
• Apply heuristic evaluation and other established UX assessment methods
• Produce reference usability reports and recommendations
• Assess whether product decisions appropriately reflect user needs and research findings
• Design expert-level evaluation tasks for AI systems operating across design and product-development workflows
• Draft reference outputs demonstrating strong professional judgement
• Develop detailed rubrics distinguishing senior-level work from generic or template-driven responses
• Review AI-generated outputs for design quality, usability, technical feasibility, and completeness
• Identify weaknesses in reasoning, execution, or product judgement and provide structured feedback

Requirements:

• 5+ years of professional experience as a Product Designer, Senior Product Designer, Design Lead, AI-native Engineer, product builder, or closely related role
• Strong experience delivering production-quality digital products, design systems, or AI-assisted development workflows
• Deep familiarity with product design, UX/UI, rapid prototyping, or AI-assisted software development
• Hands-on experience with tools such as Figma, Framer, Cursor, Claude Code, v0, Replit, or comparable platforms
• Strong understanding of user-centred design principles, interaction design, design critique, and rapid iteration
• Experience owning or contributing substantially to product design systems or component libraries
• Ability to articulate senior-level product and design judgement clearly in writing
• Portfolio demonstrating shipped product, UX/UI, design-system, or AI-assisted development work is strongly preferred
• Experience developing rubrics, conducting design critique, creating training materials, or evaluating professional work is advantageous
• Experience within a major product-focused organisation, design-forward company, startup, or notable independent product environment is highly valued
