Skroutz S.A, Greece
Job Description
At Skroutz, we have a vision to make everyone's life better by creating the most trustworthy, trouble-free, and easy to use online discovery and shopping experience. We want to provide this experience not only to our users and partners, but also to our team members.
Today we are going through one of the most exciting times for Skroutz. We are rapidly transitioning to a marketplace model, we constantly invest in technology and innovation and we acquired MyJobNow Delivery to enter in the last mile market.
If a problem is hard then it is worth solving. It's our role to isolate the problem from the solution and give users what they actually want, not what they think they want.
We firmly believe that people drive our business forward and we strive daily to build a powerful team that shares the same passion and enthusiasm for eCommerce and technology.

- Don't over anything. Don't over-engineer, over-analyze, over-regulate, you get it.
