Full Time
Before you read on, take a look around you. Chances are, pretty much everything you see has been shipped, often multiple times, in order to get there. E-commerce is exploding, and with it, parcel shipping is becoming a meaningful factor in a business' ability to succeed. Creating a compelling shipping experience for customers is hard but necessary.

At Shippo, our goal is to level the playing field by providing businesses access to shipping tools and terms that would not be available to them otherwise.

Shippo lowers the barriers to shipping for businesses around the world. As free and fast shipping becomes the norm, better access to shipping is a competitive advantage for businesses. Through Shippo, e-commerce businesses, marketplaces, and platforms are able to connect to multiple shipping carriers around the world from one API and dashboard. Businesses can get shipping rates, print labels, automate international documents, track shipments, and facilitate returns.

Internally, we think of Shippo as the building blocks of shipping. Shippos are a diverse set of individuals. We look for cultural and skill fit in every new person. Join us to build the foundations of something great, roll up your sleeves, and get important work done everyday. Founded in 2013, we are a proud team based out of San Francisco.
