Question for the tech leads out there: what is your job like?

I have had multiple startups and in one of them I have lead a team of half a dozen developers on small projects. The startup in question was a software house, so part of my job was being a sort of solutions architect (understanding what the client needed, getting deep into the processes their companies had and coming up with a software solution for them) and another part of my job was then leading the team to develop the software (and I did hands-on coding as well).

I’m now thinking of ditching the startup world and looking for a job, but I want something that pays well and I want responsibility, I work well under pressure and responsibility motivates me to work.

I consider myself a senior developer because I have worked with many different things and built many projects end-to-end. I also believe I understand quite well system design and architecture.

HOWEVER I have never worked on big scale enterprise software. I mean, I did in another company when I was hired as a junior a few years back, but the project was a complete total mess and I didn’t learn much there, I sorta already knew everything I was doing.

But I’m not that confident in my ability to be a tech lead or some higher position like that even though I have already worked as one. Problem is I did it only in small scale projects and never really had a great mentor I could look up to, I learned everything on the job.

In the end I’m wondering if the experience I have is enough to be able to get a job like that and not fuck things up.
