Did you switch within the same company? I have made attempts to apply to Solutions Engineer and Developer Advocate roles to match how my personality has changed over time, but have found that no one responds to my resume / applications, even when I have spent several years teaching, consulting, and building content and demos on the side to supplement my engineering experience and prove I can do the job. I immediately get responses and enthusiasm when I apply as Senior Software Engineer, but it seems people are skeptical of why I would want to change to Solutions Engineer or Developer Advocate when the title is not already on my resume.
