Shippos in the wild:

Our people, much like the packages we help ship, are all over the world.

For locations outside of the US and Ireland, the employment contracts are powered by Remote.com (all Shippo perks still apply - including equity!). What we want to emphasize is that you can be successful at Shippo regardless of location.

We leverage AI to review all resumes during the application phase to ensure fairness, comprehensively evaluate each submission, and mitigate bias. However, all decisions at every stage of the process are made by a real person.
