About the Project

We are starting a long-term collaboration with a client on a full-time front-end role.

This is a legacy project with a large existing codebase written without modern frameworks - no React, no Next.js.

The front-end is based on HTML, CSS (possibly SASS), and vanilla JavaScript.

Your main responsibilities will include:

  • Working with an existing legacy codebase.
  • Implementing new features and maintaining existing ones.
  • Ensuring pixel-perfect implementation according to provided designs.
  • Optimizing and refactoring existing front-end code when necessary.
  • Collaborating with other developers through Git-based workflows.

Requirements

  • 3+ years of experience in front-end development.
  • Strong proficiency in JavaScript (ES6+), HTML5, and CSS3.
  • Experience working with legacy codebases and ability to navigate complex structures.
  • Proficiency with Git: branching, merging, resolving conflicts, and contributing via pull requests.
  • Attention to detail and ability to deliver pixel-perfect layouts.
  • Good understanding of cross-browser compatibility and responsive design.
  • Upper-intermediate English or Ukrainian for communication with the team.

Nice to Have

  • Experience with SASS/SCSS.
  • Basic knowledge of build tools (Webpack, Gulp, etc.).
  • Understanding of UI/UX best practices.

We Offer

  • Full-time engagement with a stable long-term project.
  • Competitive compensation.
  • Remote work with flexible working hours.
  • Collaborative team and supportive environment.
  • Opportunity to work closely with an experienced PM, QA, and senior developers.
