info iconBasic Information

Let us introduce ourselves before we dig deeper into the job description.

OCM is one of the leading Digital Media companies in Europe. We specialize in our clients' income boost with several cutting edge technologies, either in-house, or with solid partnerships. As one of the few Google Certified Publishing Partners and, recently, a proud member of Prebid.org, we thrive in the Ad Tech industry building a solid future for the members of our team.

job description iconResponsibilities

You will be working mainly on OCM's JavaScript-driven services.

Some examples are:

  • Nodejs running on Cloud Functions and Cloud Run

         These functions work along the whole ecosystem of GCP, interacting with MemoryStore Redis instances,                         BigQuery tables, PubSub messaging, Firestore datasets, other Cloud Functions written in Python etc.

  • ES6 JavaScript (using either webpack, or browserify) for usage on our publishers' websites, to supply our wonderful services
  • Advanced Ad Serving
  • DOM manipulation

This may look brief, but trust us, it's not. Behind your code, lay several other dependencies that need to be addressed (updated, maintained etc.) on a daily basis. Especially now that we are contributing directly to prebid.org, there is a lot to be done, not only for OCM, but the whole ecosystem.

Our work is organized with tools like:

  • Slack
  • Gitkraken
  • Wrike task management
  • Zendesk
