8 years...that's all? Hell, around here we measure time by decades...
All kidding aside: the "experience" requirements list shows that the project is likely in a state of complete disaster where the supposed "architects" simply couldn't pick a technology so barfed all over several competing ones.
For javascript: jQuery AND AngularJS/bootstrap.
Database: MongoDB AND Oracle. - okay, not quite so bad, but still.
Web services: RESTful, SOAP AND mulesoft?
Build server: Gradle, Jenkins, Hudson AND Bamboo? Are they just hoping for *someone* that knows what CI is in order to implement it for them?
Testing: SPock, jUnit, Geb - (I'm hoping that's what they are using Geb for )
Given the location, the crapshoot of tools involved, the fact they want a Jr. Dev with 8 years exp and that CI is listed 3 times - good indicator that mgmt is currently pissed off that things aren't talking to each other - I'm guessing this has "healthcare" written all over it. If so, no wonder that beast cost like a bazillion dollars to build -- but I'm hoping that I'm wrong. Either way, the job looks like the winning candidate would be stepping into a shit storm.
