Senior Software Engineer

At Criteo, we connect 1.2 billion active shoppers with the things they need and love. Our technology takes an algorithmic approach to determining what user we show an ad to, when, and for what products. Our dataset is about 40 petabytes in Hadoop (more than 30 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.

Challenges of this role

In order to cope with the load, we have opened 15 datacenters around the world, hosting a total of 30k servers. We forecast as much as 50k servers in the coming years. In such a fast growing environment, the tools conventionally used by hosting and network engineers are no longer enough. 

The team you will join aims at inventing and building the next generation tools that will allow the 50+ hosting and network engineers at Criteo to scale up, open new datacenters and extend existing ones at an even greater pace. 

Such an ambitious undertaking includes (not limited to): 

- revisiting asset management 
- assisting with datacenter design over constraints 
- automating cabling specifications
- streamlining intervention process on hardware 
- exploring custom hardware qualification 
- as well as being creative with visualization 

Strong candidates qualifications

We are looking for talented developers who:  

- have at least 5 years of successful professional experience 
- get things done and know what it means to put code into production 
- are proficient with at least two languages of different paradigm 
- feel responsible for the success of his/her whole team

Bonus points

In addition, it would be awesome if you could also bring: 

- prior knowledge about datacenter design, ramp-up and operation 
- expertise with Python, Django and/or Javascript
- hand-on experience with Chef
- good intuition about UX and web UI

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.
