Frontend Development Intern (React + Next.js)

Internship

Mactores

What you'll do?

Product development

  • Assist in designing, building, and maintaining features across the Aedeon frontend ( React + Next.js ) under the guidance of senior engineers.

  • Work with product managers, designers, and backend engineers to understand requirements and help take features from spec to shipped, tested release.

  • Participate in sprint planning, backlog grooming, and retrospectives, and start building a product-first perspective.

Learning release discipline

  • Learn how features are owned end to end — from development through deployment and post-release validation.

  • Practice breaking down tasks against sprint timelines and flagging blockers early.

  • Shadow how the team coordinates with DevOps and QA to keep releases clean and repeatable.

Testing and quality

  • Learn test-driven development: write test cases before code, under mentor review.

  • Help write test cases for features you work on — functional flows, edge cases, and regression scenarios.

  • Get exposure to AI-assisted tools for generating test coverage, and to automated test suites ( E2E, integration, unit ) wired into CI/CD .

Collaboration and documentation

  • Write clear, well-documented code and submit pull requests for review.

  • Document your work features, test plans, decisions in Confluence or equivalent, in a way others can follow without you in the room.

What we're looking for?

Frontend fundamentals

  • Currently pursuing, or recently completed, a degree in Computer Science, Engineering, or a related field (final-year students welcome).
  • Working knowledge of React.js fundamentals components, state, hooks.
  • Familiarity with HTML5, CSS3, and JavaScript/TypeScript basics.
  • Some exposure to Next.js, Git , and modern frontend tooling is a plus, but not required, we'll teach you.
  • No prior professional experience required; personal projects, coursework, or hackathon work count.

Mindset

  • Curiosity about how production software actually ships — not just how it's coded.
  • Comfortable asking for feedback and iterating quickly on it.
  • Genuine interest in testing discipline and quality, not just feature output.

You'll be preferred if you've

  • Any exposure to AWS services (S3, DynamoDB, Cognito) through coursework or personal projects.
  • Familiarity with Playwright, Cypress , or any automated testing framework.
  • A GitHub profile or portfolio showing projects you've built.
