A goaltender is a goalkeeper: the player who tends the goal, meaning they look after it and try to stop shots. The word is at home in North America, and you will hear it most in ice hockey. A soccer report in Britain will almost always say goalkeeper instead. Same job, different dressing. It feels a little more official than goalie, which is the short, friendly form. Though actually, even at a hockey rink, fans still shout “goalie” more than “goaltender”. Tender here is a person who tends something, not the adjective meaning soft.

守門員。美加用法，尤指冰球；台灣講足球多半仍說守門員或門將。
