Senior JavaScript Developer


Hello! We’re the Ads Interface Team , a group of people making waves in Nordic advertising.

We develop the Admarket platform, where advertisers can book their campaigns directly by themselves to be displayed on top sites in Sweden and Norway. Our goal is to provide the best possible experience and features for them and make our platform the cream of the crop in the world of self-serve advertising.

Tech-wise, we’re big on JavaScript, with React leading the way.

Our Technology Stack:

  • Frontend: JavaScript (+Typescript), React (React Query, Sagas, Formik, React Testing Library, and more)
  • Backend: Node.js (Express)
  • Tools: Babel, Webpack, ESLint, Prettier, Husky, and more
  • CI/CD: Travis CI, GitHub Actions
  • Infrastructure: AWS, Kubernetes
  • Version Control: Git & GitHub


Every day we’re improving our platform to make it the best one and now we need YOU to help us reach our goals! In this role, you will be working on the Admarket platform, collaborating closely with Project Managers, UX designers, Quality Assurance Managers, and - of course - software developers from our team and other teams across our fantastic Ads Tech department.

  • In this role you will be working with Javascript with a focus on the client side (React), but also with Node.js on the backend.
  • In our team, collaboration is the key - we enjoy working together inside the team and collaborating with other teams.
  • We’re bringing our JavaScript and React expertise for a user-friendly experience.
  • We have a very strong knowledge-sharing community in our Ads Tech department, so you can expect a lot of opportunities to improve your skills!
  • We love to experiment and tweak for top-notch ad products.


  • Solid JavaScript and React skills.
  • Front-end tools know-how (Webpack, Babel, ESlint, Prettier, you know the deal).
  • Appreciation for quality code and delivering excellence.
  • Effective communicator and a team player – we value collaboration.

​​This will be a bonus:

  • Familiarity with the Node.js ecosystem and a nod to backend aspects
  • Familiarity with AWS.

We work in a hybrid way and would like to catch up with you at our vibrant and colourful office in Kraków 1-2 days per week. This allows for collaboration and meaningful connections with the team. If you’re not the working-from-home kind of person, you are of course welcome in our office every day!

If you’re ready to contribute to reshaping Nordic ads, enjoy experimenting, and can align with our team spirit, we’d love to hear from you! Let’s make Admarket even better together.
