PE Operating Role

Interesting in getting some insight & guidance from this group on best approaches to make the transition into a PE operating role.

Background: 6 years in tech/IT sales & leadership positions with a PE backed firm, developing new markets, assisting w/ GTM, helping to integrate sales/customer success teams post acquisition, & increasing overall revenue through net new reoccurring business.

I am trying to make the transition to working with PE fund to assist with their portco ops & help improve their overall fund value. From my understanding, most of these roles are occupied by former c-level executives. Has anyone seen or know of a path into these roles besides that? Am aware that Insight Partners has a "sales center of excellence growing" with more lower level professionals & these operating roles are becoming more relevant to many funds that invest in the tech space.
