Wisebits — is an international IT holding with a strong technical team!

Our key product is a high-load video hosting platform used by millions of people worldwide every day. With over 15 years on the market, we’ve built a professional team that values engagement and initiative.

If you’re excited about working with a high-load product and want to have an impact on its development, join us!

Who we're looking for: a Frontend Developer to join our video player team.

What you’ll be working with:

  • Our codebase is primarily written in vanilla JavaScript, with some occasional work in Svelte. Previous experience with Svelte isn’t required—it’s a lightweight framework that’s easy to pick up.
  • There’s also some legacy PHP code you may need to work with from time to time, although we’re gradually phasing it out.
     

What we expect from you:

  • Strong command of vanilla JavaScript (ES2015+), a solid understanding of how the language works, and experience conducting code reviews;
  • A good understanding of client-side and server-side rendering;
  • Hands-on experience with at least one popular UI framework, such as React, Vue, or Svelte;
  • Good knowledge of TypeScript 4+;
  • A solid understanding of object-oriented programming;
  • A willingness to dig into the code and understand how things work, even when using AI-powered tools;
  • The ability to work independently and take ownership of your work.
     

Nice to have:

  • Experience with video-on-demand technologies, HTML5 video, or HLS.js;
  • A general understanding of backend development, particularly PHP and Node.js;
  • Experience with CSS preprocessors such as LESS or SCSS, as well as the BEM methodology;
  • Experience writing tests with Jest and Testing Library;
  • A solid understanding of asynchronous programming and multithreading;
  • Good judgment and an eye for quality :)
     

What we offer:

  • No bureaucracy and flexible working conditions.
  • Extended benefits package, including private medical insurance, tax support, language courses, professional education, and all necessary hardware.
  • Relocation support: coverage of travel expenses for you and your family, visa assistance, and the first month of accommodation.
  • A friendly, international team that values professionalism and open collaboration.
  •  

Work format: Remote 

Salary:  from €3,500 net per month. The final compensation level may be higher and depends on relevant experience, skills, and overall match with the role requirements.
