Who we are looking for

OpenX, a leading provider of digital and mobile advertising technology, seeks a Senior Cloud SRE (Site Reliability Engineer).

OpenX serves 100 billion ad requests per day and operates worldwide. We are currently in the process of migrating our entire infrastructure footprint into Google Cloud Platform (GCP).

Similar to Google’s approach to SRE, you should adhere to the engineering discipline that combines software and systems engineering to build and run large-scale, massively distributed, fault-tolerant systems.

Much of your software development focuses on optimizing cloud-native systems, orchestrating cloud infrastructure and eliminating manual work through automation.

The ideal candidate has extensive experience with software engineering practices, building and supporting on-demand, burstable, virtualized and cloud-native environments on major public cloud providers (GCP preferred).

Excellent communication skills are required in order to successfully interact with globally distributed OpenX teams operating in a 24x7 manner.
