Criteo – Why Work For Us?

We are a global community, united by our contagious energy and hunger for performance. We are challengers, go (Go, GO)-getters, innovators, makers, logicians, and technical magicians. We dissect, debate, and deliberate, dreaming big and aiming high.

Belonging to Criteo means having the freedom to drive your ideas. Taking risks, moving quickly, and enjoying every moment. When you combine our computational power and unparalleled datasets with the intelligence of our people, anything is possible. 

From our entrepreneurial beginnings to the success we share today, it’s been a journey of global proportions. But through it all Criteo wouldn’t be the company it is today without the amazing people behind it.

We create impact at scale

We serve 5 billion ads a day. That’s about 4 million requests per second. We push the limits of deep learning and AI. And we don’t plan on slowing down. From intern to engineer, our people make a real impact. As a collective, we are hungry to succeed and push each other to be the best. Sure, it’s a LOT of hard work, but it’s also incredibly rewarding.

We go, Go, GO

We are all about moving quickly, innovating constantly and delivering real change. Here you can take every opportunity and run with it. It’s your chance to drive your ideas and have the freedom to make them happen. In return, we expect you to be all in.

We connect through playful energy

Our best perk is amazing people. While we take our work seriously, we love to have fun and laugh along the way. Every office is filled with equal measures of hard work and playful energy. From yoga to rooftop parties, early morning kale smoothies to late night karaoke sessions – we do it all, together. 

Be part of something big. 600 TB of daily shopper data big. 

We’re a company that’s sharply aware our world is primarily driven by technology. At Criteo we face some of the most challenging, but interesting problems in the tech industry. We work at a scale of speed, performance and complexity that few others in the industry can compete with. Every day is different and we’re proud to make it a culture that always challenges your skills.

Our 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: You will work with diverse perspectives, alongside global team players and some of the brightest minds in the industry

    I have been working at Criteo full-time (More than a year)


    Impressive tech stack.

    Still a good mix of startup spirit and big company: 'No fear' approach on the one hand and all needed resources to try on the other (talents, infrastructure). If a project failed/late/killed - happens, keep moving (no blame/punishment).

    Proactivity is encouraged and expected: no matter how junior you are, new ideas are welcomed (of course there is a challenge to get them planned). I.e. there is a Hackathon every year which gives the winners an opportunity to work on their projects.

    Internal mobility: managers try to take into account engineers preferences and help to change the scope if a guy doesn't want to work on the topiс anymore (unfortunately not always possible, but the effort is away bigger than in my previous companies). Also, there is a cross-offices Voyager program: any engineer can join another R&D team for a few weeks to learn new stuff.

    Diverse environment: >10 nationalities for appx 100 people in the office.
    Work-life balance: no work during the weekends or late in the evening, flexible working hours (people can shift a bit their schedule when needed, can WFH occasionally; no official WFH policy though).

    Reasonable management: most managers have regular 1-1s with their direct reports + occasional ones with the rest (i.e. anybody can request a 1-1 with any Director or VP); top management is open for discussions on any topic (even negative anonymous reviews are being discussed in a positive manner: 'lets brainstorm together what we can do better')


    Working with HQ in Paris is challenging due to 9 hours difference + lots of technical dependencies (management tries to mitigate it by having isolated projects when possible, but it's still hard).
    Less variety of projects than in Paris (natural for any non-HQ office and difficult to change).
    Diving stock price (and no recipe to fix it so far)
    Quarterly planning is heavy and takes lots of time.

    Advice to Management

    Be even more transparent on future plans and performance review procedures to reduce some employees anxiety about these topics.

    Average Interview


    I applied through other source. The process took 5 weeks. I interviewed at Criteo in August 2013.


    Talent Manager was super charming and did a great job of selling the position/company. She also provided a very clear picture of what I'd be walking into. The rest of the interview panel had a good understanding of my background without me having to tell too much - it was clear they knew the industry/function well.

    Interview Questions

    • it may sound silly but the MD asked me "Why Criteo? why should we hire you?" and I was caught a bit off guard.   Answer Question


    got what I asked for right off the bat
