What You'll Do:

  • As a backend engineer at Criteo you'll build first-in-class business systems to support our Retail Media Platform. Our systems are designed and optimized to handle billions of ad requests daily, ensuring low latency and high reliability.
  • You'll tackle complex challenges in data modeling, performance tuning, and modernizing legacy code to meet the demands of a rapidly evolving ad tech ecosystem
  • Design, develop, ship and maintain backend systems to support our advertisers and retailers advertising needs
  • Understand product and customer priorities, and balance those against operational and technical needs
  • Guarantee top quality code; practice code reviews, unit tests, integration tests, end to end tests in a continuous integration environment
  • Work with over 400 million SKUs, and decide which products ads to serve in less than 10ms
  • Work with Product teams and other cross-functional stakeholders to design products that customers love and that support the reliability and quality they need

Who You Are:

  • You are passionate about shipping high-performance, reliable, and efficient code in a fast-paced environment
  • You take ownership of your work and proactively drive initiatives forward
  • You thrive on solving complex problems, fixing issues, and bringing creative technical solutions to life—because coding is your passion, not just a skill
  • You are a strong communicator and a collaborative team player, eager to work cross-functionally and efficiently with others
