My older sibling always seems to judge me and undermine my interests and achievements. We both graduated from reputable universities in our respective fields (mine being technology and theirs being politics), and have good jobs in our fields. We've always been fairly successful in our lives, despite differences in interests.
We have both moved out from our parents' place and thus don't see each other very often. However, whenever I see them they always nitpick and undermine what I'm doing with my life. For example, I recently accepted a position at a reputable medical company. However, their response to this news was, "I wish you would work in a more 'respectable' field" (i.e. military defense or politics, in their mind). This greatly hurt me given I had worked incredibly hard for the job offer.
Whenever I try to stand up for myself, I'm met with either continued judgment or something along the lines of "I'm your older sibling, it's my duty to pick on the younger sibling". While I understand the jest, the nitpicking and judgment are constant, and given the little amount of time I see them on a yearly basis, I would much prefer a celebration of seeing each other, and not constant bullying. Whenever there's a family visit and I see them, I usually leave the event with a sour mood and a great deal of stress. It's gotten so badly recently that it makes me not want to spend any more time with them.
Are there any other ways I can approach these situations without instigating further conflict?
EDIT: To clarify, my sibling is usually serious about their criticisms. It's very apparent to me when they're joking, but in the example above (and other times referring to hobbies, career, other life choices, etc.) they are not.
Side note: I am located in the US
