UI Engineer Intern Full Time

About the Role

Marketeq is hiring a UI Engineer Intern to support frontend implementation across our full development pipeline, from local development, to staging validation, to production release support.

This is an unpaid, part-time internship designed for a Master’s-level student or recent Master’s graduate who already has real frontend experience and wants hands-on exposure to production-grade product development. This is not a beginner frontend role. You should already be comfortable building user interfaces, working with modern frontend frameworks, reading documentation, solving problems independently, and using AI-assisted development tools to move faster without sacrificing quality.

The work will fall into two main modes depending on the ticket: new frontend screen builds and frontend/API integration work.

On new frontend screen tickets, you will help take Figma designs and turn them into working frontend screens using AI-assisted tools such as Claude CLI, OpenAI Codex, Cursor, or similar tools. The goal is to reach strong visual accuracy first, then refine the implementation into clean, responsive, production-ready frontend code.

On frontend/API integration tickets, the frontend may already exist, and your role will be to connect it to backend APIs that the engineering team has already built. This includes authentication flows, API states, loading states, empty states, validation, error handling, and edge cases.

You will work alongside our engineering and QA teams. You will not run official QA cycles — that is handled separately — but you must be QA-minded in how you build frontend and full-stack work. Before handoff, you are expected to test your own implementation carefully, check the expected user flow, review edge cases, confirm data limitations, validate acceptance criteria, and catch obvious issues before QA receives the ticket.

You will also contribute to the documentation that supports your tickets, including user stories, acceptance criteria, edge cases, data limitations, and implementation notes. The goal is to help you learn how real product teams move frontend work from idea, to implementation, to review, to staging, and eventually into production.

This role is best for someone who is frontend-first, detail-oriented, independent, comfortable using AI tools, QA-minded, and serious about becoming a stronger product-minded UI engineer.

Internship Details

Role Type: Unpaid Internship

Schedule: 15–20 hours per week

Duration: 4–6 months

Location: Remote

Eligibility: U.S.-based applicants only

Academic Credit: We support academic credit where available through your school or university

Start Date: Immediate availability preferred

Applicants must be currently based in the United States and legally authorized to participate in a remote internship in the U.S. We are unable to sponsor visas for this internship.

What You’ll Do

• Build new frontend screens from Figma designs using AI-assisted workflows such as Claude CLI, OpenAI Codex, Cursor, or similar tools
• Translate Figma designs into responsive, production-quality frontend code
• Support frontend implementation across local development, staging validation, and production release workflows
• 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, and edge cases
• Maintain and extend existing frontend components, design system patterns, and responsive layouts
• Use existing component libraries and project conventions instead of inventing unnecessary new UI patterns
• Debug frontend and full-stack integration issues
• Self-test your work before QA handoff, including functional behavior, user flows, edge cases, data limitations, and acceptance criteria
• Think through error states, empty states, broken flows, and unusual user behavior before submitting work for review
• Contribute to ticket documentation, including user stories, acceptance criteria, edge cases, data constraints, and implementation 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

Required Experience

• Currently pursuing or recently completed a Master’s degree in Computer Science, Software Engineering, Human-Computer Interaction, Information Technology, or a related technical field
• 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 using AI-assisted development tools such as Claude CLI, OpenAI Codex, Cursor, GitHub Copilot, or similar tools
• Basic full-stack understanding, including how frontends connect to backend APIs
• Experience consuming REST or GraphQL APIs
• Familiarity with authentication flows such as OAuth, JWT, sessions, or role-based access
• 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 without needing every small step explained
• Portfolio, GitHub, shipped project, or frontend work samples we can review

Strong Preference For

• Candidates who are clearly frontend-focused, not backend-only developers trying to casually move into frontend
• Candidates with strong UI judgment and attention to visual detail
• Candidates who can compare their implementation against a Figma design and spot layout, spacing, typography, and responsiveness issues
• Candidates who can use AI tools effectively but still understand the code they are shipping
• Candidates who can test their own work before asking someone else to review it
• Candidates who think through user flows, edge cases, error states, empty states, and data limitations before submitting work for review
• Candidates who do not treat QA as the first person responsible for finding obvious frontend issues
• Candidates who can document assumptions, edge cases, and limitations clearly

What You’ll Learn

• How production frontend work moves from design to local development, staging, QA handoff, and release
• How to work inside an existing codebase with established conventions
• How to use AI-assisted development tools in a real product environment
• How to improve frontend implementation quality through code review and staging feedback
• How to connect frontend screens to backend APIs
• How to think through frontend quality before formal QA review
• How to document user stories, acceptance criteria, edge cases, and data limitations
• How to work with engineering, QA, and product stakeholders
• How to write cleaner PRs and communicate implementation decisions clearly

Nice to Have

• Experience with accessibility standards such as WCAG
• Experience with frontend performance auditing
• Experience with CI/CD tools such as GitHub Actions, Vercel, Netlify, Render, or AWS
• Familiarity with error tracking or session replay tools such as Sentry, LogRocket, or similar
• Experience with Playwright, Cypress, Chrome DevTools, or other frontend testing/debugging tools
• Experience working with design systems or component libraries
• Experience with responsive dashboards, marketplaces, SaaS products, or admin panels

Who This Role Is Not For

This role is not a good fit for someone who is brand new to frontend development.

It is also not a good fit for someone who only wants to work on backend systems and has little interest in UI implementation, responsive layouts, visual accuracy, component behavior, and frontend quality.

You do not need to be a senior engineer, but you do need to have enough frontend experience to take a ticket, understand the expected outcome, use available documentation, ask thoughtful questions when needed, test your own work, and make real progress without waiting for every tiny instruction.

Application Requirements

To apply, please send:

• Your resume
• Your GitHub, portfolio, or frontend project samples
• 2–3 examples of frontend or full-stack work you personally built
• A short note explaining your experience with Figma-to-code implementation and AI-assisted development tools
• Your weekly availability
• Whether your school supports academic credit for internships
