Job Description

Fueled by a fundamental belief that having access to financial services creates opportunity, PayPal (NASDAQ: PYPL) is committed to democratizing financial services and empowering people and businesses to join and thrive in the global economy. Our open digital payments platform gives PayPal’s 375 million active account holders the confidence to connect and transact in new and powerful ways, whether they are online, on a mobile device, in an app, or in person. Through a combination of technological innovation and strategic partnerships, PayPal creates better ways to manage and move money, and offers choice and flexibility when sending payments, paying or getting paid. Available in more than 200 markets around the world, the PayPal platform, including Braintree, Venmo and Xoom enables consumers and merchants to receive money in more than 100 currencies, withdraw funds in 56 currencies and hold balances in their PayPal accounts in 25 currencies.

Messaging Infrastructure team builds and manages the messaging platform that enables asynchronous communication across loosely integrated systems for all of PayPal. This platform serves a variety of SLA requirements that span the entire spectrum of messaging and streaming – from lossless transactional (aka ACID) messaging (zero data loss) to low-latency messaging (in milliseconds) and high throughput streaming (6M+ messages per sec and growing). If you are excited about pushing a Kafka cluster that streams around 500 billion events per day to go beyond 1 trillion events per day, then this team is a perfect match for you. If the thought of working on a platform that moves $2B+ in daily payment volume excites you, you’ve come to the right team. If you believe in building services whose Quality-Of-Service (QoS) parameters should be as easy as adjusting the dials of a thermostat, then let’s chat more.
