What is a QA Engineer at OpenX?
At OpenX, a QA Engineer plays a critical role in maintaining the integrity, performance, and reliability of one of the world's largest independent programmatic advertising exchanges. The adtech ecosystem operates at an immense scale, processing billions of ad requests daily with millisecond-level latency requirements. In this high-throughput environment, even minor software regressions can lead to substantial financial losses, compromised user experiences, or ad quality failures.
As a QA Engineer, you will be responsible for ensuring that the complex web of ad servers, real-time bidding engines, and publisher integrations functions flawlessly. Your work directly impacts the quality of ads served to millions of users globally and protects the revenue streams of both publishers and advertisers. You will collaborate closely with software developers, product managers, and operations teams to build robust automated test suites, validate data pipelines, and investigate complex ad delivery flows.
This role requires a unique blend of traditional software testing expertise, strong data validation skills, and deep domain knowledge of digital advertising technologies. You will not just be writing basic test scripts; you will be analyzing complex systems, validating massive data sets, and ensuring that OpenX continues to deliver industry-leading ad quality and marketplace efficiency.
