Junior JavaScript Fullstack Developer

Accelerating business and talents

In just 5 years Brainhub has become one of the fastest-growing companies in Europe, according to Clutch, Deloitte, and the Financial Times. We’re all about keeping the pace by helping our partners never slow down and accelerating the skills and potential of our team. Currently, we have more than 80 talented people on board: developers, UX/UI designers, QA engineers, DevOps engineers, Delivery Managers and Agile coaches. Together we build digital products for companies like National Geographic or Paradox Interactive.

We’d love to have you on our team, too.

Become a team member, not an employee

Brainhub is a place where you can work the way you like and create your own career path. 

There are no corner offices, regional managers, or assistants (to) regional managers here. We have a lean and pretty flat structure. You’ll have a real impact on organisational decisions and become a vital part of the team that deals with challenges together and grows together.

At Brainhub, we:

  • Align people with projects they’re most passionate about,
  • Focus on long-term projects to build a decent product and help clients succeed. We take care of our team, so we make rotations between projects possible,
  • Carefully pick our clients to make sure they fit our culture and work ethic,
  • Help each other and share our knowledge (we organise our own meetup called DevDuck),
  • Actively work on improving our BizDevOps excellence,
  • Dedicate our efforts towards creating a team of T-shaped persons: capable in many things and expert in, at least, one.
