you don't really "join" you earn reputation points...

anyway : you need to be MR3 or higher,

get their sigil from the console in your orbiter,

equip the sigil on your warframe, and do missions (part the affinity earned in mission will be converted into syndicate rep),

after you get enough rep, you can rank up and do specific missions to earn more rep...
