Sr. Data Engineer - Nexus / Core Data

Blizzard Entertainment games don’t just begin with game ideas, or end once those games are released. A lot more goes into the creation of a Blizzard product than the work of developers—and we support our games for years after they’re in the hands of gamers world-wide. 

Blizzard Entertainment is looking for a Senior Data Engineer to join our Global Insights team and shape the next generation of the global data infrastructure that powers all of analytics at Blizzard.

In this role, you will be tasked with the evolving design, development, maintenance, and overall integrity of a reliable, scalable data platform that empowers analytics at scale, is a trusted source of truth for analytical data, and provides the security of governance and control without impeding innovation or agility.  You will be an integral part of a cross-functional team dedicated to ensuring both strategic cohesion and operational integration between all components of the Global Insights tech stack; proactively identifying and responding to evolving user trends and needs; maximizing system and service stability, reliability, visibility, and overall output; and establishing best practices, providing ongoing consulting, training, troubleshooting, and optimization.

Ultimately, you will be responsible for providing accurate, timely, reliable, and ultimately useful data to the analytical data ecosystem.  This mandate involves everything from the discovery, access, and integration of source data into the ecosystem to guaranteeing its health and robustness within that ecosystem to modeling and presenting that data in a manner that allows stakeholders within the ecosystem to perform their duties effectively.  You will work closely with other members of the Core Data Team and the Tools and Technology team and will partner fully with the franchise Data Engineers to create a full understanding of the use cases and needs of stakeholders; you will use this deep understanding to develop standardized models and approaches that can then be leveraged by all other parties.  You will ultimately be responsible for designing, developing, implementing, and evolving pipeline components – processes, procedures, technology, et. al. - that together promote the maximum visibility and trust in the analytical data ecosystem overall.

Our ideal candidate is the personification of the Khala: a common thread binding all users together; a leyline into a reservoir of power, giving each individual the ability to tap into something both greater than their own island and shared between many; a give-and-take between the individual and the group by which individuals can take from the group what they need and the group can see what those needs are and make adjustments; something that exists above and beyond, held to a higher standard with a perfect clarity of purpose, but which ultimately exists to serve.
