Full-Stack AI Builder Internship — Claude CLI / Codex Full Time

About the Role

We are hiring a Full-Stack AI Engineer Intern — Frontend-Focused to support frontend implementation, frontend/API integrations, and AI-assisted full-stack development.

This is an unpaid, part-time, graduate-level internship for current Master’s degree students or Master’s graduates only. Applicants must be current U.S. residents and should already have hands-on experience with frontend development, full-stack integrations, and AI-assisted coding tools.

This role is full-stack, but the main focus is frontend development. ou should be comfortable building user interfaces, working with modern frontend frameworks, translating Figma designs into responsive screens, connecting frontend screens to backend APIs, and handling loading, error, validation, empty, and edge-case states.

You will use tools such as Claude CLI, OpenAI Codex, Cursor, ChatGPT, GitHub Copilot, MCP tools, or similar AI-assisted development tools to understand documentation, generate implementation plans, build features, debug issues, refactor code, and prepare work for review.

You will work alongside engineering and QA teams, contribute to implementation documentation, and learn how product work moves from requirements to frontend implementation, API integration, staging, QA handoff, review, and release.

• Debug frontend, backend, API, authentication, data flow, and integration issues
• Self-test work before QA handoff, including user flows, edge cases, API behavior, and acceptance criteria
• Think through broken flows, failed API calls, invalid inputs, permission issues, and unusual user behavior before submitting work
• Contribute to ticket documentation, implementation notes, API notes, and AI workflow notes
• Write clean PRs with clear testing and implementation details
• Receive feedback through code reviews, staging reviews, implementation walkthroughs, and QA handoffs

Required Experience

• Currently pursuing or completed a Master’s degree in Computer Science, Software Engineering, Human-Computer Interaction, Information Technology, Artificial Intelligence, Data Science, Machine Learning, AI Engineering, Computational Analytics, or related technical field
• Must be a current U.S. resident
• Minimum 2 years of frontend development experience (coursework, internships, freelance work, projects, bootcamps, or shipped products)
• Strong experience with HTML, CSS, JavaScript, and TypeScript
• Experience with at least one modern frontend framework (React, Next.js, Vue, Svelte, Angular, or similar)
• Experience translating Figma designs into responsive frontend interfaces
• Experience building responsive layouts for desktop, tablet, and mobile
• Experience with component libraries, design systems, reusable components, or Storybook-style documentation
• Experience with frontend state management (React state, Context API, Redux, Zustand, TanStack Query, Apollo Client, or similar)
• Experience connecting frontend screens to backend APIs and consuming REST or GraphQL APIs
• Basic full-stack understanding (APIs, authentication, databases, services, deployment environments)
• Familiarity with authentication flows (OAuth, JWT, sessions, role-based access)
• Experience using AI-assisted development tools such as Claude CLI, OpenAI Codex, Cursor, ChatGPT, GitHub Copilot, or similar tools
• Ability to use AI tools to generate code, then review, debug, refactor, and validate before submitting
• Comfort with technical documentation, architecture notes, implementation plans, and existing codebase patterns
• QA-minded approach with ability to self-test work before QA handoff
• Comfort working with Git (branches, commits, PRs, code reviews)
• Ability to work independently, read documentation, and solve problems while asking thoughtful questions
• Portfolio, GitHub, or frontend/full-stack work samples for review

Strong Preference For

• Frontend-strong candidates who can also handle full-stack integrations
• Hands-on experience using Claude CLI, OpenAI Codex, Cursor, ChatGPT, GitHub Copilot, or similar AI coding tools
• Candidates who can use AI tools effectively while understanding the code they ship
• Comfort guiding AI tools with technical documentation, repository context, implementation plans, and existing code patterns
• Strong UI judgment and attention to visual detail
• Ability to compare implementation against Figma designs and identify layout, spacing, typography, responsiveness, and interaction issues
• Understanding of frontend/API integration, authentication flows, validation, API states, and error handling
• Ability to debug AI-generated code instead of blindly trusting it
• Ability to test work before requesting review
• Ability to think through user flows, edge cases, failed API calls, invalid inputs, permissions, and data limitations before submitting work
• Candidates who do not treat QA as the first line of defense for obvious frontend or integration issues
• Clear documentation skills for assumptions, edge cases, implementation notes, and limitations
• Comfort working within an existing codebase instead of rebuilding systems from scratch

What You’ll Learn

• How production frontend and full-stack work moves from design to local development, staging, QA handoff, and release
• How to work inside an existing codebase with established frontend, backend, API, and documentation conventions
• How to use AI-assisted development tools in a real product environment
• How to use Claude CLI, OpenAI Codex, Cursor, MCP tools, and repository context to support real implementation work

• How to document user stories, acceptance criteria, edge cases, data limitations, API behavior, and implementation notes
• How to work with engineering, QA, and product stakeholders
• How to write cleaner PRs and communicate implementation decisions clearly
• How to use AI tools as an engineering accelerator without losing ownership of code quality

Nice to Have

• Experience with accessibility standards such as WCAG

Who This Internship Is Best Suited For

This internship is best suited for candidates with some real frontend development experience and want to grow into stronger full-stack AI-assisted engineers.

It is especially well suited for candidates who enjoy frontend implementation, responsive layouts, component behavior, Figma-to-code work, API integrations, authentication flows, and AI-assisted development workflows.

This internship is also a strong fit for candidates who want to learn how to use tools like Claude CLI, OpenAI Codex, Cursor, ChatGPT, GitHub Copilot, MCP tools, and repository documentation to support real product implementation.
