Mentally commit to staying a year and re-evaluate. That is long enough to see what happens with your (now vested?) options and the companies prospects, and you may feel very different about the work and job in that time. Life is too short to spend all of it doing something you don't like; but frankly it's also too long to bail immediately every time we don't love the work you are doing or aren't passionate about a companies mission.
