Job Description

At PayPal (NASDAQ: PYPL), we believe that every person has the right to participate fully in the global economy. Our mission is to democratize financial services to ensure that everyone, regardless of background or economic standing, has access to affordable, convenient, and secure products and services to take control of their financial lives. We’re a purpose-driven company, and our beliefs are the foundation of how we conduct business every day. We’re guided by our core values of Inclusion, Innovation, Collaboration, and Wellness. Collectively, these values inspire us to work together as One Team with our customers at the center of everything we do, and to take care of ourselves, each other, and the communities in which we live and work. We challenge the status quo, ask questions, and find solutions. Join us as we enable the hopes, dreams, and ambitions of millions of people around the world.

Job Description Summary The Commerce Solutions and Services Engineering (CSSE) team is responsible for building solutions and platforms used by all PayPal’s merchants, focusing on the largest customers – the Enterprise, Channel Partners and Marketplaces customer segments. We build applications, services and platforms that allow PayPal customers to accept payments globally across all channels, including the Commerce Platform for Enterprises (, Commerce Platform for Platforms and Marketplaces (, Braintree platform (, Hyperwallet platform (, among many other responsibilities. As a Principal Engineer in our team, you will be leading development to define how large-scale merchants worldwide integrate with the current and next-gen PayPal Commerce Platforms.

These platforms combined are responsible for processing more than half of PayPal’s transactions worldwide, so this is a high-stakes role – there are very few mission critical APIs like this in the world, with this kind of scale and complexity, and that power so much commerce and so many businesses worldwide. You will play a key and critical role defining how the platform developer experience is shown to the world.
