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 Streams Infrastructure team at Linked In builds and operates highly scalable and available pub-sub, stream processing and data pipeline services for all of Linked In’s data platforms and applications. Kafka, Samza and Brooklin all originated at Linked In and form the backbone of the streaming infrastructure. More than 20+ trillion messages/day are ingested into the Kafka clusters from tracking site engagement to metrics and logging, while over 4+ trillion messages/day are processed by Samza for real-time data analytics that powers member notifications, threat screening, ads infrastructure etc.

Data pipelines which include Brooklin moves over 6+ trillion messages/day and powers tens of thousands of data streams including Kafka mirroring.
