I've been working professionally as an software engineer for nearly twelve years and found myself in a medium to large size corporation in their CTO group as their cloud solution architect and principal architect for close to four years now in a very challenging domain. I've managed this trajectory without an undergraduate, jumping straight into work with IBM after completing my associates and a few IT certifications.

I find myself enjoying working with the C-suite team and defining our higher level goals and trajectory more than I do on specific technology these days. I also feel like the current position, though admirable to most, could be where I retired if I am complacent and I'm not done climbing yet. I can't imagine going back to finish my computer science degree in an attempt to use it as a stepping stone to a MBA or executive program but I'm not certain how to take the next step. Thoughts? Suggestions? Thank for reading.

I would try to clearly define your career goals before making the next step.

For (most) people in your position, taking one (or two) years out of their career to take an MBA can help catapult them to the next level.

However, there are some fields and companies where it's hard to get out of the game for that long. Of course, there are part-time MBAs / Online programs for this type of person.

The lack of undergraduate degree might be a dealbreaker for many schools.

Look at programs in the UK, maybe?
