The Discipline 

Our engineering discipline builds the technology that enables MoonPay to learn quickly and scale easily. We organise in small cross-functional squads of 3-5 engineers and an embedded Product Manager, Product Designer and Product Data Analyst. We currently have 3 squads across Payments / Finance, Compliance / Fraud and Core Product / Growth. Over time these squads will split out and we are also building new squads focusing on new revenue streams and product verticals. We’re pragmatic and believe in having fluid structure, this means people can move between teams or specialise.
