Having just taken a job as a l Lead SRE in a large consultancy despite not being skilled or experienced enough I'm terrified that I'll struggle to move to a new org solely because of my job title. It's jarring how much of an impact it has made on me and I don't really know what to do about it. I'm aware that it's only really a problem when I move but I don't think the work and tech I'll be exposed to will help me reach a level where I'll be confident.

Just rephrase the job title on your resume so it's faithful to reality but not the literal title.

At my last job, my formal title was "Systems Integration Engineer", which has a real industry definition as recognized by various engineering fellowships. Since I did very little formal Systems Integration at the job, I labelled myself as a "Cargo Logistics Engineer" on my resume. It worked fine.
