**Company Description** MORE THAN A CARD READER, MORE THAN A DIGITAL ACCOUNT: a complete solution for our customers, a business built by people, for people. We were founded with the purpose of improving lives, sharing dreams and achievements. We do this through innovative solutions that transform, with simplicity and efficiency, the financial management of individuals and businesses. And now, we are part of Serasa Experian: together, we are building a better future for everyone, expanding opportunities here and now. In addition to our customized business solutions, we are also partnering with Serasa on consumer-facing solutions, driving a series of initiatives that contribute to financial education, financial management, and financial empowerment of the population. Through the Serasa platform, we enable the offering of the Serasa Digital Account—a payment account that allows consumers to make various payments, including debt negotiations via Serasa Limpa Nome, quickly and securely. At PagueVeloz, we want to do things differently—to be disruptive—welcoming and attracting entrepreneurs and demonstrating that the financial market can indeed be: less bureaucratic, slower, outdated, and far less complicated. To achieve this, we are building a strong, diverse, and fearless team. Here, diversity is an ally of transformation. Therefore, we encourage and safeguard applications from professionals who are: women; Black, Indigenous, Asian, and/or multiracial individuals; members of the LGBTQIANPN+ community; persons with disabilities (PcD); and people facing vulnerability.
