Project description:
Our partner is a market leader in developing complex ETL and machine learning solutions. With published authors and award-winning data scientists who contribute some of the major machine learning and distributed data technologies such as Apache Spark, they are a friendly, passionate group of engineers making a career out of building great software for their customers.

They are dealing with hundreds of millions of data points every day, generated from over two thousand data processes running through workﬂows, huge distributed computations in spark, streaming data coming in twenty-four hours a day at hundreds of times a second.

Their engineering culture is underpinned by sharing knowledge, coaching, and growing together. You will have the opportunity to explore/innovate new technologies, mentor engineers, and lead Technology initiatives. You will enjoy this role if you love writing code, learning cutting edge new technologies, solving problems, and winning as a team.

As a Data Engineer, you will be working across their entire stack, so a real passion to drive the product and technology forward is something that they value. Your responsibilities will include helping with a vision for the future architecture of this complex data system, adding innovative ideas that use the latest cutting edge technology. You will work closely with Web and Data Science teams to deliver user-centric solutions to their customers and become an expert in developing high-quality technical solutions.
