Full Stack Engineer - Backend Focused at Ansa

It’s time that payments work for merchants, not the other way around. Ansa is building a branded wallet solution to increase customer retention and unlock new growth opportunities.

Ansa 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.

We’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? Let's chat!
