To be honest, it sounds like an extraordinarily interesting field to work in:
"This is a one-of-a-kind opportunity for someone who lives and breathes spying and espionage to become part of a world where wild fantasies of undercover operations become reality. If you think you have what it takes, we want to hear from you."
Unfortunately their opportunity is out of reach, as I'm not in the UK nor Israel -- and they're not specifically seeking technical skills, per se.
