What you’ll be working with

We’re an agile environment using cutting-edge technology

Build products that make a difference

Marfeel is a product-led company. We use results and data to keep creating better and better solutions to our publishers’ challenges.

As part of our product team you’ll be part of:

  • A 180+ strong team with 70% focused on product development
  • An agile environment delivering 4.8 billion ad impressions per month
  • Solutions built using the latest technology
  • Continuous delivery and 200 daily deploys to production
  • Developments that affect 30 million users a day
  • Leading contributions to the open source community

The best part for me is how data-driven the company is. All the changes in the product get analysed and analysed again. We make changes based on this, not on gut feelings.
