You are going to have more success if you take ownership of this yourself. At any given job / company, you will 'learn' / become an expert in their internal legacy systems, while your knowledge of "Algorithms and data structures - Imperative and OO programming - Control flow - Design patterns" + "Front-end frameworks - Back-end frameworks - Cloud services - Testing - Automation and Deployment" will atrophy.

Employers look for people who have learnt this stuff outside the company, and bring them in to teach their current staff who haven't kept up to date.
