Senior Automation QA Engineer (JS)


Corva AI is a technological product company from Texas that creates cutting edge as-it-should-be analytical platform for Oil’n’Gas. Its mission is providing real-time analytics from all possible aspects for every technological process. With providing this solution Corva has become a real innovator in this field. Within only 1.5 years in production, it has captured nearly 10% of the US market in its initial niche (drilling operations) and has strategic development contracts with top companies on the market like Exxon Mobile and Chevron.


For an end-user, Corva is a customizable dashboard with a great number of widgets, that provide real-time analytics to your 10” tablet (for people working afield) or 60” display (for people working in a center of control). Every widget is a front-end for a particular domain engineering model, that has its own computation core and data flow.

From the inside, the product is a framework that provides a holistic foundation for data processing: gathering, storing, processing, streaming and visualizing. The general idea of this framework is that new data applications (widgets, their computation cores and data flows) should be created in a short time (within one month or so).

Today the product has an incoming data flow of 10Tb and manages up to 100 mln API requests per day. The product manages about 200 of atomic factors and provides analytics on more than 50 domain engineering models (it is for drilling operations only). And this amount grows daily.
