Job description

From enabling a smooth shopping experience to ensuring we fulfill our customers’ orders efficiently in our warehouses, there’s a wide range of products to work on. Product teams are also supported by the work of our platform teams on key technologies and infrastructure.

Also, we don’t hide what we do. Instead, we open-source with the community that helped us grow. Here’s proof: http://picnic.tech
