Looking for pipeline example

New to Circle CI.
I have Java projects, some use Maven and some use Gradle.
I’d like to build the artifacts in one job, and then run 3 downstream jobs in parallel: owasp scan, sonar static analysis, and integration tests.
How to do I carry the artifacts build in job #1 into my downstream jobs?
Is that even the right question?
How do people get the most parallelism out of their maven/gradle projects?
