The official specialist descriptions can be found here.

 Specialists can be hired every 18 hours starting at hour 4 from the start of the game.  The specialists presented for hire are mostly random but will consist of 1 Offensive, 1 Defensive, and 1 Other specialist. 

The selection process as outlined by the dev: 

Here's the process from the devs: 

  • Each specialist is classified as attack, defense, or other
  • We take 3 copies of all attack specialists and put them in a "deck" and "shuffle" it
  • We similarly create defense and other decks
  • Each round we draw one specialist from each deck and present it to the player 
  • The player selected specialist depletes the pool of specialists in the deck for the next pick, making duplicates less likely[1]
