Senior Backend Software Engineer (Booking Platform & APIs)

About this role

• Most travel platforms are built around overnight rooms. ResortPass is building the platform for everything else a hotel can offer
• A day pass is sold by capacity. A cabana is reserved as a unit. A massage needs a time slot, provider, or room. Events have tickets. Food and beverage may be a product, an add-on, or part of a bundle. Each category has different rules for pricing, inventory, fulfillment, and cancellation
