Do i need spare ether to commence the job

Hello everyone I’m new to this world and i have only a bit of idea on how it all works.
I wanted to know that do i need some spare ether to bond 0 k3pr and start job or i can just go with 0 ether and begin a job.

Some ETH is required to bond, and do the initial jobs for the first 14 day period.

Thank you @andre.cronje for your advice, fan of your work!
