Design Expert

Role Overview

• Mercor is seeking senior product design and AI-assisted development professionals to build evaluation tasks for AI systems operating in rapid prototyping, product design, and human-AI collaborative coding contexts.

• The workflows are calibrated to the design complexity, user experience stakes, and scope of major product development and design systems work.

• This role builds worlds across two subdomains: a Vibecoding track (AI-assisted, natural-language-driven software development and rapid prototyping) and a Design track (product, UX/UI, and visual design systems). Experts qualified in either or both subdomains are encouraged to apply.

• Contributors design scenarios, draft reference outputs, and write rubrics that capture how senior product builders and designers think.

Key Responsibilities

• Construct scenarios spanning rapid prototyping and iteration cycles, design system development, and cross-functional product-design-engineering collaboration.

• Build tasks across AI-assisted application development, natural-language-to-code workflows, and rapid prototyping (Vibecoding); and UX/UI design, design systems and component libraries, user research, and usability testing (Design).

• Develop scenarios involving tools such as AI coding assistants (Cursor, Claude Code, v0, Replit) for the Vibecoding subdomain, and Figma, prototyping tools (Framer), and design systems tooling for the Design subdomain.

• Apply subdomain-specific methodologies (iterative prompt-driven development for Vibecoding; human-centered design principles and heuristic evaluation for Design), and produce reference prototypes, code artifacts, design specs, and usability evaluation reports.

• Author rubrics that distinguish authentic senior-level product judgment from generic tutorial-level or template-driven work.

Ideal Qualifications

• 5+ years working as a product designer, design lead, or AI-native engineer/vibecoder at a major product- or design-forward company (Figma, Airbnb, Notion, Linear, or a notable independent/startup product builder).

• Direct ownership of product design systems or AI-assisted development workflows shipped to production.

• Fluency in vibecoding or design tooling, plus understanding of user-centered design principles and rapid prototyping practices.

• A portfolio of shipped work is strongly preferred in place of a formal credential; prior rubric, training, or design critique authorship is a plus.
