Job Description

At Criteo, our culture is as unique as it is diverse. From our offices around the world or from home, our incredible team of 2,700 Criteos collaborates to develop an open and inclusive environment. We aim to create a place where people can grow and learn from each other while having a meaningful impact. We work together to achieve our goals, push boundaries, and share successes. All of this supports us in our mission to power the world’s marketers with trusted and impactful advertising.

All new Criteo products are built in a self-service first perspective, which help us collect client's feedbacks as quickly as possible to make them autonomous. In particular, in order to extend our reach, we are always looking for new ways to onboard clients and partners. This can be by making the setup of your first Criteo Ads easy as a breeze, or by providing developers who wants to use our APIs all the tools they need to build and manage their applications.  

The API Developer Experience team is building the applications and framework that make the Criteo API possible. Our focus on developers is both internal and external: building a usable & consistent public API should be made trivial for our internal teams, using the Criteo API should be seamless and powerful.

What you'll do

  • Get the functional needs from Product, from R&D teams looking to expose APIs and from our API Guild recommendations on the shape of APIs.

  • Iterate with UI/UX to design user friendly interfaces,

  • Implement what has been designed,

  • Test the applications with unitary, integration and end to end tests,

  • Review code of team members to ensure we commit only high-quality code that will stand the test of time,

  • Interact with multiple multi-cultural R&D teams to ensure the right communication between the client-facing applications and the other Criteo systems,

  • Continuously deploy the applications,

  • This is only part of the job. Using the information collected through meetups and conferences, you will strengthen our systems by building a state-of-the-art application, whether in terms of framework or library, or in terms of best practices (testing, continuous integration/deployment strategies).

  • Our current tech stack is built using C#/ASP.NET Core on the back-end, as well as Angular on the front-end.  

Who you are

  • You believe that APIs will drive the world.

  • You are interested in Developer Experience, and want to make sure that what you ship facilitates the life of other developers.

  • You are curious about innovative technologies, eventually leading personal subjects on the matter.

  • You have experience with developing and extending large and complex systems.

  • You have worked in Agile environments and are passionate about shipping high quality code!

What is in it for you

  • You will be part of a recognized engineering R&D team in our industry with an active presence to international conferences, meetups and demos all around the globe.

  • Our culture keeps evolving, and you will be expected to contribute actively with new ideas to complement and enhance the existing programs that include frictionless internal mobility, 10% time, mentoring, technical talks, hackathons, etc.
