Senior Software Engineer, Cluster Services

At Quantcast, data is king, and the Cluster Services team knows how to process it. The unique features of our custom map/reduce implementation include a revolutionary petabyte sort mechanism; an efficient and flexible petabyte join and lookup, based on innovative data indexing and partitioning mechanisms; dynamic task size adjustment in running jobs; and a self-tuning system that learns and improves job performance without developer intervention. In the last 5 years it has allowed Quantcast to scale from processing 400 to 40,000 terabytes of data per day. For the typical ETL, analytics, and machine learning work at Quantcast, our big data processing platform is on average 4 to 5 times more efficient than the popular open source solutions.

Quantcast is looking for senior engineers to help this team build the next generation big data platform. From integrating and improving new open source technologies, to inventing your own, there are many opportunities to have a tremendous impact.
