STEM OPT extension for IB as a CS major

Hello! I recently graduated college with a degree in computer science. I have an opportunity to work in IB. Didn’t get H-1B picked this year, so have to apply for STEM extension. Does it sound like a possibility to relate an IB job with a CS degree to be stem extension eligible? I am unsure about taking up this opportunity until I’m sure that I would be approved for a stem extension. Any insights would be appreciated!
