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!   🤔 What you will be doing? Scale our core ledger that tracks both digital and physical money movement. Scale our card network integrations that power in-store payments. Build and maintain complex reconciliation infrastructure to make sure we never lose a cent across our partner bank, payment processors, merchants, and card networks. Build and scale our financial reporting & accounting integrations that allow our merchants to close their books seamlessly. Design and maintain our payment APIs and SDKs that make for frictionless integration. Design and build features that prime us for enterprise-readiness, including SSO and RBAC. Design and ship products that help merchants drive end-user adoption and engagement, creating a flywheel of user spend (i.e. our incentives engine and analytics). Scale up our cloud infrastructure as we move towards fully containerized, blue-green deployment. Own end-to-end design, implementation, and release of features. Design and implement engineering processes. Prototype new ideas and iterate towards the ideal user experience. Contribute to our engineering infrastructure.
