Is there an apocalyptic religious movement in Iran? Similar to American Evangelists hoping for Armageddon?
The entire Shia sect is basically an apocalyptic religious movement. Has been since the start when Ali, the first Imam and fourth Caliph for the Sunnis, was assassinated, his sons following him, only for the assassination mastermind to usurp his Caliphate. Combine that with the millenarianism of the Safavids in the 15th and 16th centuries.

It's more of a Jihad/Martyrdom ideology that's driving them.

That's a rather different issue, and luckily one that at least causes a lot less problems in practice. Sam Harris has some decent material on why this is(a lot of it comes down to important differences in doctrine).
There is a potential for bias among Iranian converts to Christianity, but for those whose stories I've listened to, the common answer is yes, there is an apocalyptic religious movement in Iran.
