Software Engineer - Project Offline

At Criteo we face some of the most challenging, but interesting problems in the IT industry. We work at a scale of speed, performance and complexity that few others in the industry can compete with. Our data is not big it's absolutely HUGE. We have about 40 petabytes in our Hadoop storage (more than 30 TB extra per day), we take less than 10ms to respond to an ad request and we deliver billions of ads per day.

To help us solve these challenges, Criteo is looking for the best of the best in terms of engineering talent within our cool and geeky environment!

Challenges of this role

The team is known as “Project Offline”, as its mission is to bridge the gap between what our clients' users do online, and what they do in their real world “bricks n' mortar” stores. Our goal is to expand Criteo's core online solution to include data from the real world (such as in-store user behavior) to build new products for our clients. The team will develop, and iterate on, potential product offerings, to explore the market opportunities related to offline re-marketing. This is your chance to make a difference in a project that will become huge for Criteo.

The project team is organized as a small startup inside Criteo: we are a small team, working alongside Sales, R&D, Product, Finance, all as one team. While each developer has his specialty, everyone will get to work on all technical aspects, just like a start-up team would. This is a fabulous opportunity, with huge potential for learning and career development. You will learn things on this project that will stick with you for your entire career.

Strong candidates qualifications

In terms of skills, here is a list of things we do (we don't expect our next members to know all of it, but you should expect to learn anything):

·  Backend: Java/Scala, NodeJS, Protocol buffers, Kafka, Hadoop, regular backend work.
·  Geo-Localization algorithms: numerical data processing, optimization, classification, learning. You don't have to be an expert in learning or optimization, but understanding how it works in general will be necessary to be able to figure out what goes wrong.
·  iOS code: Swift coding, client to server communication under unreliable network, Bluetooth magic, making code run in the background, etc.
·  Android code: Android Java, client to server communication (in sometimes unpredictable network conditions), Android services, resilience, etc.
·  Plumbing and tools: You will also spend some time changing batteries and do some wall climbing to check on the beacons' state. Things will break, bugs will be detected, and fixes will be made.

Criteo R&D Culture

·  Empowerment – We believe in hiring the best engineers in the industry and then letting them get on with what they do best – designing, coding and releasing state of the art software.
·  Mobility – In our Voyager program our engineers get to pick which team they want to work on for 2-4 weeks, boosting collaboration, networking and maybe even leading to switching teams.
·  Agility - We work in a fast pace environment where we build and release stuff frequently to deliver value soon and adapt to changes quickly.
·  Variety – We have many ways to get your code to production including our Hackathon, 10% projects, Voyager and more.
·  Multicultural – We have engineers from all over the world for you to interact and exchange ideas with.

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, conferences, etc.
