Is there a career path that connects IT with passion for foreign languages?

tldr: I'm a software developer looking for a career path utilizing both my 10 years of experience in IT and my love to foreign languages and linguistics. Any ideas?

(this is quite a long post, feel free to skip it and simply answer the tldr question above)

About me: I'm a software developer with about 10 years of experience. I feel I'm "pretty good" at it, and my bosses and colleagues generally agree. I'm fine financially and never had problems with finding a new job. I worked with various technologies, from mobile apps through web to the embed software. I was also engaged in activities like architecture designing, UI/UX preparation, and now I'm even a part time Scrum Master. I was, and still am passionate about all this - I like improving my skills, learning new things, etc. To be frank: I'm very happy with the fact that I'm being paid for something I really like.

Recently however, I started to have a feeling that I need some change. I'd like to try different things and I'm afraid that if I stick to what I'm doing now, I won't discover other things I could like even more. I briefly thought about leaving IT altogether, but given the relative stability of this career path and the fact that I've already put so much effort into it, I don't think it would be a good idea. However, changing to something else but still within IT, or to some multidisciplinary field where it plays a big role, could be a very interesting option for me.

One of my biggest passions except programming are languages (natural) and linguistics. I may not be extremely good at it, but I've always found it very interesting. In the area of languages, adding to my native Polish, I managed to learn two foreign ones - German and English - to a relative fluency. I'm currently trying to learn Finnish and vaguely think about other Nordic languages. Regarding linguistics, I've learned quite a lot of theory behind the languages I speak, reaching quite far from what's usually useful for language learning (including historical information, theory of languages, etc) - very interesting things, but for me still secondary to actual usage of foreign languages.

So I started to wonder, if there exists a career path, where I could connect my two big passions. I was thinking, talking to friends and family, but despite some ideas popping up, my main concerns are still not solved, thus my turning to Reddit.

Below are the three most obvious ideas I (or someone I asked) stumbled upon - all seem to have major flaws. Or at least that's what I believe - feel free to point out my wrong assumptions.

Obvious idea #1: stay within the IT, but move to another country to learn and use the local language there - the problem is, I already did it.

I'm a Polish national, but I moved to Germany a few years ago. There were a few reasons to that, but one of the most important was that I always liked German and this way I got a possibility to learn it in a place where it's daily used. This worked well, I'm currently more or less fluent. Now however, I'm pretty happy with my life here and don't really consider moving somewhere else permanently (but if I had a chance to travel often enough to justify learning more languages, I'd be happy to try it!).

Obvious idea #2: go study what you love - sounds cool, but that doesn't really solve the problem.

There's one more thing to my IT career: I've never graduated from a university. I studied Computer Science for two years, but decided to stop and go directly to the industry. In retrospective, it was a good choice, but now I'm thinking about going back to school and studying something completely different. And obviously, something related to languages or linguistics pops up in my mind here too. I could go study general linguistics or a specific languages family for a few years and be perfectly happy with that.

But, this somehow moves the problem for later and doesn't solve it. The only direct benefit from such a study would be a formal graduation which could help, even in IT (in case my career ever stucks because of the lack of formal education). But I don't want to spend 3-5 years of my life for just a piece of paper (one reason why I left the uni), I want to learn something that I could utilize in my career.

Basically, if I find a good career path for later, I'll be fine to study something from this field. But that's not easy. All obvious jobs "after linguistics" like teaching, translation or research, may be interesting, but they wouldn't let me utilize my IT experience, and frankly - are plainly worse financially (I'd be so happy if these turned out to be wrong assumptions!).

Obvious idea #3: find an international IT company and help in cooperation with people from different countries - sounds great, but is it even possible?

When researching language-related jobs, you sometimes see mentions of international companies, which use language and cultural knowledge in international business. Sounds logical and I could imagine this working fine in a field like trade. But in IT? Here everybody and their moms speak English anyway, I doubt there would be an actual added value from knowing native languages of the international partners (again, please point out if I happen to be wrong about that).

Bottom line: I have a lot of doubts and don't know what I actually want. Pretty vaguely I'd like something where both my IT and (current and future) language/linguistics skills make a difference and aren't merely additions. For example, at my current work, I have many colleagues with different mother tongues, but learning them would be useless, since everything is discussed anyway - that's something I would prefer to avoid.

Any ideas?
