What’s a tech related career for someone who has a learning disability

From experience in dev, there are multitudes here with learning disabilities of many different kinds. Without knowing more specifics, I'd say just about anything is open to someone from a wide range of learning disabled backgrounds. Personally, I'd recommend a person with a learning disability particularly focus on what he or she is intensely interested in. It's generally a good idea, but intense interest can help push through a lot of challenges, from my own experience.

I know a couple of devs with dyslexia, their variable naming/spelling is pretty atrocious but they are stellar engineers.

Learning disability is a too wide term to answer your question.
