Why here

Gemini AMPM is employee-owned: stay, and you own part of the company. The range on this page is basic salary, deliberately wide, because where you land in it depends on tickets, experience and patch; overtime, call-out and the van sit on top. Progression runs on the Academy ladder, and a human reads every application within three working days.

Tell us what you are worth: the target salary box on the form is there for a reason, and we would rather pay the market than pay an agency.
