Front-end (react) Developer

MobPro (Mobile Professionals) is looking for an experienced front-end (react) developer who can perfect the usability and performance of our very own real-time bidder platform.

What's this about?

We have an automated platform which, based on our clients’ needs, automatically bids on more than 20.000 bids per second. Our goal: to show relevant advertising to the right consumers’ smartphones.

Every month we design and execute dozens of mobile advertising campaigns. For this, our Sales and Campaign teams use the interface to create, optimise and monitor those campaigns.

In order to keep up with a growing number of advertising campaigns and opportunities in the advertising industry, our platform and its features are constantly being refreshed. You will be responsible for taking our existing interface to the next level. Every day you will facing new challenges that requires experience in how to detect and how to solve it proactively.

Your responsibilities as a front-end developer:

  • Using your React skills, you transform highly complicated concepts into smart, clean and outstanding interfaces.
  • Working with our Sales and Campaign teams, you will determine the requirements for the new features and updates to the interface.
  • The new interface will communicate with the backend using APIs. You determine which APIs you need and your developer colleagues will take care of the rest.

Get to know your team:


Our tech director. With his contagious enthusiasm he knows how to trigger you. During work and a table-tennis game.


Kees likes building and experimenting on our systems. He is the data engineer who keeps our engine smart and powerful.   


Maria loves to plan and implement software architectures! She left Lisbon to join MobPro as a back-end developer.


This Canadian Python developer never takes an answer for granted. Whether it’s about machine learning or the best maple syrup. He is up for discussion. 

Our setup

The development team at MobPro uses Agile methodologies. We are a team of 7 developers, that works together to coordinate changes and additions to the API. We also work very closely with our Sales and Campaign teams. The Sales and Campaign teams use the interfaces and dashboards to create, optimize and monitor advertising campaigns. When the Sales and Campaign teams identify new opportunities in the market, it is our task to implement the technical aspect of the solution. We roll out updates every day and instantly get feedback on the features we deliver.

Innovating you

Together we'll make it happen

Is this you?

You have already experienced professional projects building great interfaces, not only websites. Although you may be not have actual design skills, UX is your second nature.

  • UX and IA is second nature to you.

  • Experience with automated testing would be an asset.

But also:

  • Sitting back and relax is not your thing. You identify new opportunities quickly and takes action immediatly to make new things happen.
