About AI Training and This Work

AI training (also called data labeling or human feedback work) is the human side of building AI: people create, evaluate, and refine the examples and judgments models learn from. UX work helps shape how people interact with AI-powered products and how those systems present outputs to users.

This role focuses on product design and user experience tasks that will be evaluated through text-based assessments and interview tasks. Your design decisions and research approach help ensure products are usable, accessible, and aligned with business goals.

• You will produce practical UX artifacts (wireframes, prototypes, research summaries) that inform development.
• Assessments are text-based and focus on how you think about user problems, trade-offs, and accessibility.

The Role

We are seeking an intermediate UI/UX Designer (contractor) to create intuitive, user-centered, and visually appealing digital experiences. You will work closely with product managers and developers across the product lifecycle to translate business requirements into effective design solutions.

This listing is a fixed-price contract with a payment of $100 (USD). The work is remote and open worldwide. The engagement includes an AI interview component that will evaluate design thinking and technical proficiency via text-based tasks.

• Employment type: Contractor (remote, worldwide).
• Payment: Fixed-price $100 USD.
• Subject matter: Product design and user experience.
• Data type for assessments: TEXT; Label types used: EVALUATION_RATING, TEXT_GENERATION, QUESTION_ANSWERING; Labeling software: OTHER.

What You'll Do

Deliver clear design artifacts and research that guide product decisions and development. Work pragmatically to solve usability problems and justify trade-offs with evidence and thinking that non-designers can follow.

• Conduct user research and synthesize findings into actionable insights and personas.
• Create wireframes, interactive prototypes, and high-fidelity mockups (responsive-first).
• Define or contribute to design systems and reusable components.
• Run or design usability tests and iterate on designs based on results.
• Communicate design decisions and trade-offs to product managers and engineers.

Requirements

Candidates must meet the following requirements and be prepared for an AI interview that assesses these competencies in text-based tasks.

• 2+ years of UI/UX design experience with practical product work.
• Strong understanding of user-centered design principles, wireframing, prototyping, and responsive design.
• Proficiency with design tools such as Figma.
• Experience conducting user research and usability testing, and translating findings into design solutions.
• Knowledge of accessibility best practices and responsive design standards.
• Ability to collaborate with cross-functional teams and clearly explain design decisions and trade-offs.
• A portfolio demonstrating contributions to end-to-end design projects (research, flows, prototypes, outcomes).

How the AI Interview and Evaluation Work

This role includes an AI interview that assesses your skills through written tasks and evaluations. Expect scenario-based prompts that ask you to analyze usability problems, propose designs, justify trade-offs, and produce short design artifacts or outlines in text form.

Evaluations will use text-based label types (EVALUATION_RATING, TEXT_GENERATION, QUESTION_ANSWERING) and are reviewed to measure reasoning, clarity, and practical application of UX principles.

• Prepare to describe processes, show research summaries, and explain decisions in clear written form.
• Assessment tasks focus on Figma workflows, research synthesis, accessibility, responsiveness, and collaboration scenarios.

How To Apply

Apply with a link to your portfolio and a brief cover note summarizing a recent end-to-end product design project (problem, your role, key decisions, and outcome). Create an OpenTrain account (free) if you don't have one — applications and the AI interview happen on the platform.

Shortlisted candidates will be invited to complete the AI interview text tasks. Payment details: this engagement pays a fixed $100 USD upon completion as specified in the listing.

• Include portfolio links that highlight research, wireframes/prototypes, and measurable outcomes.
• Be ready to complete text-based design scenarios during the AI interview.
