Trending @Accenture; I want to switch into the data engineer role.

I am currently working as an implementation specialist on CMS called Magnolia. I wanted to switch into the data engineering role. The thing is, my deal falls under Accenture operations, and data engineering roles are under Accenture Technology. How difficult is it to switch to Tech role from operations? Can I apply from the Accenture career portal directly, or do I need to go via manager? Please advise 🙏

PS.. I am on the Accenture contract and not on payroll.
