DevOps Engineer

PubNub runs a globally distributed “Data Stream Network”, a cloud service that developers use to build and scale large real-time apps. We have thousands of customers, and process billions of realtime messages each month. We power a variety of realtime applications including multi-player games, ride dispatch services, social events, online auctions, education apps, telecom infrastructure and more. We develop software close to the bare iron and optimize performance in microseconds.

The Engineering team is responsible for designing, developing, operationalizing, sustaining and scaling PubNub’s Data Stream Network. This includes our secure, distributed messaging bus as well as all add-on services and data pipelines including Storage/Playback, Presence, Access Management, Push Gateways and more. We are a strong team of Engineers and Architects who are low on drama and high on results. Our mission is to use uptime, performance and scale as tools, to extend the fabric of real-time possibilities and stay true to the trust and confidence reposed in us by customers to deliver delightful user experiences. We believe that teams, which balance linear progression and non-linear innovation, achieve the best results. Consequently, we place the team ahead of the individual when solving problems and celebrating achievements. If you are on a journey to seek a team whose norm is to swarm and perform, we are your destination! As a DevOps Engineer, you would be directly responsible for championing tools and technologies; adopting and adapting frameworks and services used/needed by current and forward looking features. In net terms, you’ll serve as a productivity multiplier for other developers in the team.
