We are looking for a Big Data Engineer to our partner company to help their team improve and maintain their big data pipelines at scale. The team is contributing directly to the success of the company's Identity Engine by building systems that process terabytes of transaction data every day.

The network ingestion team provides the data for our data scientists – both in terms of labeled transactions for experimentation and model training, and for calculating features for production evaluation of transactions over the deployed models. This involves various processing steps on a large amount of incoming transactions – including the calculation of various complex features called the network signals –, which we execute with distributed computations.
