About Us
QupleTech is data-driven automated advertising platform for mobile gaming. We've aggregated most important traffic sources, including multiple ad networks, ad exchanges and Facebook under one roof, and built advanced machine learning-based optimization engine, that automatically selects best traffic from these sources and ensures above-market ARPU, LTV and LT, while decreasing CPC/CPI.

Java Engineer

Company & Product

We are working on next-gen data-driven programmatic advertising platform for mobile gaming. The product allows game marketers to acquire most valuable users for mobile game through display and video advertising.

We collect and analyse audience data to predict gamers behavior, and show personalized, high relevant ad.

From engineering standpoint, our product is SaaS service consisted of several technically sophisticated elements: high performance Real Time Bidder, very fast audience data storage, ETL engine for processing of complex data, Prediction System based on machine learning.

We deal with true high load and process tens of thousands of complex requests each second, so we build horizontally scalable clustered architecture to ensure reliable load tolerance.

Our data is really big, we store, process, transform, and search on tons of fuzzy structured data sets, so we apply a lot of complex data management approaches like NoSQL, in-memory storages, Hadoop, distributed storing, data sharding and replication.

We face with strong algorithmic challenges, specifically tree and graph processing, search algorithms, multi-dimension optimization tasks etc. 

The heart of our solution is Prediction System which is machine learning statistics engine designed for user consuming behavior forecasting.

So, we solve the tasks that were never solved before and we scout smart guys who looking for challenge and know how to deal with challenge.
