Is LinkedIn a purely Java shop? Do they use other stacks besides Java? (not including frontend js, html, css, etc. )
SRE uses python, AI uses scala
What AI nowadays uses Scala?
Most internal tooling is developed using Python. This includes all UI and CLI apps and automation systems. Some tools use Java but those are few. Some legacy adtech still has scala in the front end but those should be replaced soon if they haven’t been already. Some of our data systems use Scala like parts of Kafka. A few data systems and infra are developed in c++. Scala is used most by people who use Spark such as data engineers and AI. Everything else is Java. Java without Spring.
Yes, SRE org is all python/flask
