Note: The job is a remote job and is open to candidates in USA. Marketeq Talent is offering a graduate-level internship focused on front-end engineering and full-stack product development. The intern will translate designs and product requirements into working features, create implementation documentation, build and debug functionality, and validate product behavior using Codex, MCP tools, Claude, and terminal-based workflows.
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
