Many companies and startups appreciate engineers who can deep dive into tasks without constant interruptions. Have you considered roles like a Backend Developer, Systems Engineer, or even Research positions in the tech field? These often require minimal interaction compared to some other roles, and you can predominantly rely on your technical skills.
Remote work has also gained a lot of traction over the last few years, and you could look for positions that allow for this flexibility. Being remote could reduce the number of meetings and allow you to focus on tasks. Also, written communication becomes vital in remote positions, which sounds like a strength of yours.
If you're open to branching out, tech writing or documentation might be a direction to consider. Here, your technical knowledge would be invaluable, and you'd be mainly communicating in writing.
Lastly, have you thought about freelancing or consulting? With your experience, you could take on projects that align with your strengths and set boundaries on your terms.
Whatever you decide, remember that everyone has their unique strengths and challenges. Finding the right fit can take time, but it's out there. Best of luck, and hang in there! :)
