Ansa is building a branded wallet solution to increase customer retention and unlock new growth opportunities.\nAnsa helps innovative and growing companies by providing an enterprise-grade, white-label stored value wallet platform paired with incentive tooling. Our platform enables our customers to turn stored value and loyalty programs into a powerful growth engine that increases customer retention, drives repeat purchases, and boosts margins, all without the cost and complexity of building it in-house.\nWe’re seeking a Backend Engineer who wants end-to-end ownership of core backend systems and the chance to have an outsized impact on a product used by fast-growing consumer brands. You’ll make meaningful architectural decisions and work closely with leadership to influence both product and technical strategy. Does this sound like you?

That means we have to hold ourselves to a high bar, by design.
