Continuity banks on the assumption that the institutions people currently trust will not outlive their money. We need an actuary willing to price that assumption correctly, out loud.
Responsibilities
Model failure modes most banks are contractually unable to say out loud. Design the infrastructure layer that survives the collapse of whatever's running on top of it today. Sleep fine after doing so.
Requirements
Comfortable being the most pessimistic person in a room full of bankers, and correct about it. Prior experience at an institution that no longer exists is a plus.
