Your mission:

Build systems that make the best decision in 50ms, half a million times per second. Across three continents and six datacenters, 24/7.

Find the signal hidden in tens of TB of data, in one hour, using a over a thousand nodes on our Hadoop cluster. And constantly keep getting better at it while measuring the impact on our business.

Get stuff done. A problem partially solved today is better than a perfect solution next year. Have an idea during the night ? Code it in the morning, push it at noon, test it in the afternoon and deploy it the next morning.

High stakes, high rewards: 1% increase in performance may yield millions for the company. But if a single bug goes through, the Internet goes down (we’re only half joking).

Develop open source projects. Because we are working at the forefront of technology, we are dealing with problems that few have faced. We’re big users of open source, and we’d like to give back to the community.

To qualify for this mission:

It’s not really important what technology you’ve used before (Java, C++, C#, Scala, Erlang) – we’re looking for people who can adapt very quickly and with an open mind. Our engineers will chose and use the best tool for the job.

You like to work on a white board and are partial to post-its, we have floor to ceiling white boards and every color of sticky notes.

You love algorithms, languages that nobody knows, work on personal projects, are curious.

You are a problem solver, a fixer, and a creative technologist. We believe coding is a talent and a passion, not just a skill.

You need to be a great team worker and a great communicator.

Bonus Points:

Experience at real Internet scale, using the Hadoop stack, Kafka, Storm, etc.

Experience of Machine Learning (at scale)

Good knowledge of advertising technology
