Job description

What You'll Do:

What's the Core Product Component group?
The Core Product Component group, composed of seven agile and human-sized teams that deliver reusable business components that power and accelerate Criteo’s product solutions, ensuring consistency, reliability, and speed across the platform.
 

How You'll Make An Impact
As a Software Engineer in the Commerce Properties team at Criteo, you’ll shape how companies integrate their e‑commerce properties (e.g., tracking events) with Criteo. You’ll evolve our real‑time events ingestion back‑end with a focus on scalability, low latency, and reliability, and you’ll help imagine, design, and implement user flows that reduce client integration time by leveraging AI for guided setup, auto‑validation, and just‑in‑time assistance.
 

What You’ll Do

  • Build new capabilities and maintain our high‑throughput events collection back‑end, one of Criteo’s largest data pipelines by volume.

  • Partner with Product and Program to deliver fit‑for‑purpose architecture and reusable components across platforms.

  • Design, implement, and ship back‑end features end‑to‑end with strong testing and observability.

  • Help build web applications when needed, including AI‑assisted flows for configuration, validation, and troubleshooting.

  • Collaborate with multi‑cultural R&D teams and Internal IT to ensure robust integrations between client‑facing apps and Criteo systems.

  • Own stability, usability, and continuous delivery, raising the bar on reliability and developer experience.

  • Promote a strong engineering culture focused on quality, testing, and modern CI/CD; bring insights from meetups and conferences to keep our stack state‑of‑the‑art.

Technical environment: C#, Java, Scala, Angular, TypeScript

Who You Are:

  • You have experience building, maintaining, and evolving large‑scale applications.

  • You care deeply about high‑throughput systems and prioritize reliability, performance, and scalability in your work.

  • You’re skilled at making complex problems simple and solvable.

  • You stay curious about new technologies and adopt proven design and engineering best practices.

  • You bring a can‑do, collaborative mindset and approach problems with positivity and ownership.

  • You have experience in Agile teams and are passionate about shipping high‑quality, well‑tested code.

Bonus

  • You have experience in full‑stack development with modern JavaScript and in building web services in C#, Java, or Python.

  • You contribute to Product and UX discussions, turning customer needs into simple, intuitive solutions, and you apply AI where it clearly improves outcomes.

We acknowledge that many candidates may not meet every single role requirement listed above. If your experience looks a little different from our requirements but you believe that you can still bring value to the role, we’d love to see your application!​
