Sexist is still sexiest, even if it's coming from a woman dictating that they "step it up".
This is for a sales team. They all need to step it up, and be at their most attractive, because that's how sales works. The people they will be talking to that evening need to be persuaded that life would be so much better if you were riding their CI pipeline rather than that frumpy old Jenkins'.
This is how companies get money to pay coders to wear sweatshirts to work and not shave and still be paid good money.
