At Linked In, our approach to flexible work is centered on trust and optimized for culture, connection, clarity, and the evolving needs of our business. The work location of this role is hybrid, meaning it will be performed both from home and from a Linked In office on select days, as determined by the business needs of the team.

Reporting to the VP of Online Infrastructure
, this role will be based in Mountain View, CA, and will lead an organization of approximately 50 engineers and managers.

The Derived Data Systems team is a cornerstone of Linked In's data-driven ecosystem, responsible for architecting, building, and operating the high-performance platforms that create and manage high-value, queryable assets used by nearly every product on the site.

This team's charter spans two mission-critical platforms:

Graph Database (Liquid): The backbone for most Linked In products, providing the definitive source for all connections data. It supports real-time, high-QPS graph queries across a massive, highly connected dataset, powering features like Feed Personalization and core applications that leverage member connections.
