CDI - temps plein

Description de l'offre

Who we are
At Criteo, we connect 1.5 billion active shoppers with the things they need and love. Our technology takes an algorithmic approach to predict what user we show an ad to, when, and for what products. Our dataset is about 50 petabytes in Hadoop (more than 120 TB extra per day) and we take less than 10ms to respond to an ad request. This is truly big data and machine learning without the buzzwords. If scale and complexity excite you, join us. 

Most of all, we are creators. From designing ground-breaking products to finding unique ways to solve technical challenges at an exceptional scale, our tech teams work with state of the art methodologies to shape the future of advertising.

The Software Engineering team builds the products that make Criteo tick: from developing industry leading machine learning techniques, to building high scale/low latency real-time applications (over 5M qps, handling over 300 Bn HTTP requests daily), to delivering first class client interfaces, both API and UI, with forward-thinking UX at their core, all using state of the art technology.

What you'll do

All new Criteo products are built in a self-service first perspective, which help us collect clients' feedback as quickly as possible to make them autonomous.
The Budget & Webapps Engineering team holds a central position and provides technical solutions for UI/APIs used by both advertisers and publishers’ platforms. More specifically, we provide both product (Budget configuration APIs & external APIs) and technical (Analytics) pipelines. In partnership with Product and R&D teams, you will be working on the whole Criteo data flow: from Kafka streams (Flink), designing jobs running on the HDFS on our Hadoop cluster, building both internal & external REST services to access this data. Other topics we cover include: authentication,
analytics using Elasticsearch, emailing solutions etc. The biggest challenge is that we need to work across the whole Criteo stack. This requires a general knowledge on how to build APIs and know your way around both streaming and batch processing.

As a software engineer, you are able to:
- Understand the functional needs from Product & R&D
- Write technical specs, design and implement systems to match those
- Test with unitary, integration and end to end tests and provide quality
- Review code of team members to ensure we commit only high-quality
- Continuously deploy the applications

This is only part of the job. Using the information collected through meetups and conferences, you strengthen our system 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 stack is built around .NET CORE, running in marathon containers on Mesos, Java/Scala written jobs running on the cluster, Python, Flink library, Elasticsearch.
