At my last job I was hired to fix security issues found in some code being audited. I didn't 'write' or design the code myself. Yet the process was really just the same as regular software engineering. I wrote new code to implement algorithms that were missing, fixed validation logic, improved testing, and wrote some simple scripts to make working with some of the file formats easier. I'd have just been a 'technician' to you but IMO: it involved all the same skills as if I'd have designed it myself. You still need to know what all the code does well enough to have written it and have the skills to improve it. So I'm not sure the distinction really matters here.
