Job Description

Platform Engineer (Entry Level)


PubNub is a globally distributed "data stream" network, a cloud service that developers use to build and scale real-time applications. We power hundreds of millions of devices with trillions of monthly real-time transactions in social apps, online auctions, multi-player games, financial services, telecom infrastructure and e-commerce to name a few. PubNub is also used as the communication backbone of many Internet of Things (IoT) solutions for home automation, connected cars, retail and transportation.

When we aren't tending to product needs, forging building blocks that meet stringent availability and scale requirements, you can find us crafting beer or enjoying one at a local bar.
