Software Engineer III, Backend

Here at Shippo, we are the shipping layer of the internet and we consider ourselves to be one of the core building blocks of e-commerce.

Our mission is to make merchants successful through world class shipping. With our products and solutions, we level the playing field by providing our customers with best-in‑class solutions that otherwise wouldn’t be available to them. Through Shippo e‑commerce businesses, marketplaces, platforms and a variety of logistics infrastructure providers are able to connect to shipping carriers around the world from one API and dashboard.

We provide our customers with the most competitive shipping rates, print labels, automated international documents, shipment tracking, facilitate the returns process and more.

We are looking for a Software Engineer to join our Engineering Enablement Team! This team is responsible for finding hidden problems in our software ecosystem and solving these problems in order to enable other teams in the Core Connectivity Division to build reliable and performant shipping APIs which allow Shippo’s customers to connect to carriers, calculate rates, create labels and track their packages, allowing stream‑aligned teams to deliver value to our customers at a faster pace with higher quality.

We need a proactive, pragmatic, and collaborative person who adapts to the team dynamics and helps us find these hidden problems and design the solutions that will empower the entire division to build the best shipping API of the internet.
