Full-Stack AI Engineer Internship— Frontend-Focused, Claude CLI / Codex

Marketeq Talent is seeking a Full-Stack AI Engineer Intern — Frontend-Focused to support frontend implementation and AI-assisted full-stack development. The role involves building user interfaces, connecting frontend screens to backend APIs, and utilizing AI tools for development tasks.

Responsibilities:

• Build new frontend screens from Figma designs using AI-assisted workflows such as Claude CLI, OpenAI Codex, Cursor, ChatGPT, GitHub Copilot, or similar tools
• Translate Figma designs into responsive, high-quality frontend implementation
• Support frontend implementation across local development, staging validation, and production release workflows
• Use AI-assisted coding tools to generate, review, debug, refactor, and finalize frontend and full-stack implementation work
• Integrate frontend screens with backend APIs that have already been built by the engineering team
• Work with authentication flows, API responses, loading states, error states, empty states, validation, permissions, and edge cases
• Maintain and extend existing frontend components, design system patterns, responsive layouts, backend integrations, and project conventions
• Use existing component libraries and project conventions instead of inventing unnecessary new UI patterns
• Use Claude CLI, OpenAI Codex, Cursor, MCP tools, repository documentation, and project context to understand the codebase and complete implementation tickets
• Debug frontend, backend, API, authentication, data flow, and full-stack integration issues
• Self-test your work before QA handoff, including functional behavior, user flows, edge cases, data limitations, acceptance criteria, API behavior, and integration behavior
• Think through error states, empty states, broken flows, failed API calls, invalid inputs, permission issues, and unusual user behavior before submitting work for review
• Contribute to ticket documentation, including user stories, acceptance criteria, edge cases, data constraints, API notes, implementation notes, and AI workflow notes
• Write clean PRs with clear explanations of what changed, what was tested, and what still needs review
• Receive feedback through code reviews, staging reviews, implementation walkthroughs, and QA handoff reviews

Requirements:

• 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 a closely related technical field
• Must be a current U.S. resident
• Minimum 2 years of total frontend development experience through coursework, internships, freelance work, personal projects, open-source work, bootcamps, or shipped products
• Strong hands-on experience with HTML, CSS, JavaScript, and TypeScript
• Experience with at least one modern frontend framework such as React, Next.js, Vue, Svelte, Angular, or similar
• Experience translating Figma designs into working frontend interfaces
• Experience building responsive layouts for desktop, tablet, and mobile screens
• Experience working with component libraries, design systems, reusable frontend components, or Storybook-style component documentation
• Experience with frontend state management using tools such as React state, Context API, Zustand, Redux, TanStack Query, Apollo Client, or similar
• Experience connecting frontend screens to backend APIs
• Experience consuming REST or GraphQL APIs
• Basic full-stack understanding, including how frontends connect to backend APIs, authentication, databases, services, and deployment environments
• Familiarity with authentication flows such as OAuth, JWT, sessions, or role-based access
• Experience using AI-assisted development tools such as Claude CLI, OpenAI Codex, Cursor, ChatGPT, GitHub Copilot, or similar tools
• Ability to guide AI tools to generate useful code, then review, debug, refactor, and validate the code before submitting it
• Comfort working with technical documentation, architecture notes, implementation plans, and existing codebase patterns
• QA-minded approach to frontend and full-stack development, including the ability to self-test work before QA handoff
• Comfort working with Git, branches, commits, pull requests, and code reviews
• Ability to read documentation, think through problems, and work independently while asking thoughtful questions when needed
• Portfolio, GitHub, shipped project, or frontend/full-stack work samples we can review
• Experience with accessibility standards such as WCAG
• Experience with frontend performance auditing
• Experience with CI/CD tools such as GitHub Actions, Vercel, Netlify, Render, AWS, or similar
• Familiarity with error tracking or session replay tools such as Sentry, LogRocket, or similar
• Experience with Playwright, Cypress, Chrome DevTools, Postman, Insomnia, or other testing/debugging tools
• Experience working with design systems or component libraries
• Experience with responsive dashboards, marketplaces, SaaS products, admin panels, or internal tools
• Experience with backend development using Node.js, NestJS, Express, Django, FastAPI, Rails, Spring Boot, or similar
• Experience with databases such as PostgreSQL, MySQL, MongoDB, Supabase, Prisma, TypeORM, or similar tools
• Experience with MCP server integrations, AI agents, prompt engineering, vector databases, embeddings, or repository memory systems
• Experience building automation scripts, development workflows, or AI-assisted engineering pipeline
