Mid Level Software Engineer | Core Banking

Curitiba | On-site

EBANX is one of the most successful fintechs to emerge from Latin America — and today, we are building a truly global payments company. Our mission has remained constant from day one: to unlock access and enable companies and consumers to participate in the digital economy, no matter where they are. What started as a bold vision has grown into a platform that connects some of the world’s largest digital businesses with customers across 21 of the fastest-growing markets.

We operate where complexity exists — turning local challenges into global opportunities, and building the infrastructure that allows payments to move further, faster, and smarter. We are a team of builders and problem-solvers. We think globally, act with curiosity, and believe diversity of thought is a competitive advantage.

As EBANX enters its next phase of hyper growth, we are looking for people who want to shape the future of payments, expand what’s possible, and help connect businesses and consumers across borders. Let’s build what’s next — together.

In our Brazilian operation, EBANX has its own payment institution, duly regulated by the Central Bank of Brazil, which is connected to key regulated products such as Pix. Thus, we are looking for a Mid-Level Software Engineer to join our Core Banking Team (Payment Institution).

You will work with a team of experienced developers and be responsible for maintaining a platform that processes millions of transactional requests daily. We cultivate an engineering culture that values and promotes sustainable quality, high availability, quick feedback, meritocracy, and accountability.
