In all honesty, talking to people in an engaging way is a key skill no matter what industry you want to be in, Computer Science or otherwise.
If you really want to avoid people, you can maybe follow the stereotype of grumpy sysadmin, but even then you need to land the role in the first place.
Really just find something you are passionate about (hopefully Computer Science!) and talk to someone about it passionately. Then talk to someone else. Then someone else. Rinse and repeat until you can convince someone you really want the job they have on offer.
In some cases they will even prepare the recruitment team at the employer by explaining that you know your stuff but struggle to communicate effectively early in the process.
Find some other CS people in your country and ask around for a good recruiter.
