Full Stack Engineer - Backend Focused

Ansa · San Francisco

About the role

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. • Help grow our engineering team 🎉

👋🏼 About you • You have 6+ years of experience independently owning and driving scalable, impactful projects end to end. • Based in the SF Bay Area (or willing to relocate!) and excited about working closely in-person with a tight-knit team. • Innately curious and brave enough to consider new payment paradigms or verticals for applications, can navigate low information environments. • Execution oriented, excited by the high-ownership nature of joining a team at this stage. • Interested in building a top class engineering culture from the ground up. • Appreciates and looks for elegant solutions but understands trade-offs of robust designs/engineering vs. moving fast. • Experience building fast, reliable cloud applications.

😊 Nice to haves • Operated at a growth stage startup before. • Familiarity with Golang web frameworks, AWS, Postgres. • Experience in building one of these areas: core ledgers, money movement platforms/services, and merchant facing APIs for in-app/online POS. • Bonus points if you have experience in mentoring other team members, and have previously worked closely with designers.

🎉 Our culture

We’re a small team with a big mission. That means we have to hold ourselves to a high bar, by design. With limited resources and high ambition, excellence in quality, communication, and ownership, ambition isn’t optional — it’s how we move forward. • Ownership — if you see it, you take it. We don’t wait to be told. • Nosiness — curiosity across boundaries, asking questions, stepping beyond scope to solve problems. • High agency — proactive and self-directed. You move the work, not the other way around. • Accountability — we do what we say, and communicate proactively • Relentless drive — we work with focused intensity and follow through, even when it’s hard. • Thoughtful execution — shipping work that’s not just fast, but intentional. Think about how decisions today will affect us down the road. • Pride in your craft — we sweat the details and take our work personally, because it reflects who we are. • Kindness and trust — we give each other respect, empathy, and the benefit of the doubt. We assume good intent and act like teammates.

🥞 Benefits • Stellar health, dental, vision insurance coverage, including fertility benefits and One Medical. • Unlimited PTO and observed local holidays. • We also offer 401(k), healthcare FSA, and dependent care FSA to fit your needs.
