AI Prototype Engineering Intern (U.S.A Only)

About the Internship

• Graduate-level internship specializing in front-end engineering or full-stack product development.
• Focus on turning front-end product screens into real working software functionality within an existing codebase.
• Centered around using Claude Code, Codex, and MCP tools in the terminal to:
• Analyze codebases.
• Review designs and backend documentation.
• Create missing front-end documentation.
• Implement features.
• Debug issues.
• Refine production-ready software.
• Claude may also be used for backend-related tasks and code reviews.
• Builds real product functionality by translating front-end screens, flows, and product requirements into complete working features.

Key Responsibilities

• Work 100% inside a Codex + MCP terminal-based workflow for front-end and full-stack implementation.
• Use Claude as needed for backend-related work and code review workflows.
• Translate front-end screens and product requirements into implementation-ready functionality.
• Create any missing front-end documentation based on designs and backend documentation.
• Write and refine user stories for front-end features.
• Define and document acceptance criteria for front-end features.
• Identify and document edge cases, data limitations, backend dependencies, and functional gaps.
• Define empty states, loading states, validation states, and error states.
• Build front-end features and supporting full-stack functionality.
• Review AI-assisted code critically and refine weak implementations.
• Debug product behavior and identify incomplete or broken experiences.
• Think through QA, usability, and functional completeness before marking work done.
• Collaborate with product and engineering leadership on feature execution.
• Use Google Chrome Developer Tools in the MCP server environment to inspect, debug, and validate front-end functionality during implementation and QA review.

Requirements & Tech Stack

• Required technical familiarity:
• JavaScript / TypeScript
• React, Next.js, or similar front-end frameworks
• Front-end architecture and component-based development.
• APIs and backend integration patterns.
• Debugging and validating application behavior.
• Product-minded front-end implementation.
• Terminal-based development workflows.
• Must-Have Qualifications:
• Prior hands-on experience with Figma, Claude Code, and Codex.
• Prior hands-on experience with MCP server integrations.
• Comfortable working in a vibe coding workflow.
• Strong front-end development experience.
• Strong QA mindset.
• Ability to translate front-end screens into real functionality.
• Ability to create missing front-end documentation from designs and backend documentation.
• Ability to write user stories, acceptance criteria, edge cases, data limitations, and error states.
• Comfortable working 100% in the terminal.
• Able to work inside an existing codebase.
• Strong analytical and problem-solving ability.
• Strong attention to detail and ability to spot incomplete requirements, broken states, weak implementations, and UX or logic gaps before a feature is considered complete.

Qualifications

• Master’s degree required in one of the following or a closely related field:
• Software Engineering

• Experience working inside existing production codebases.
• Experience with front-end QA or product QA thinking.
• Experience writing implementation documentation before development begins.
• Experience identifying API and data constraints that affect front-end behavior.
• Experience refining UI flows based on real product logic.
• Experience with repository-aware AI tooling and documentation-driven development workflows.
