We participate in the construction and evolution of the Group's digital ecosystem, developing applications and services across multiple domains (channels, products and services, cross-functional operations, data/AI, risk & compliance, and corporate support).

We combine human judgment with automated execution to enhance software quality and multiply team productivity.
We are looking for professionals who do more than just code, and who enjoy designing both the "what" and the "how" of software: understanding problems, formalizing them into specifications, and delegating implementation to AI agents.

- Develop software following Secure Software Development Lifecycle (SSDLC) principles.
- Collaborate with architecture and security teams to capture principles, technical decisions, and regulatory requirements, explicitly incorporating them into the context and workflows of AI agents that perform development tasks.
- Drive the adoption of automation for application behavior analysis (response times, resource consumption, logs, etc.).
- Work with multidisciplinary Agile teams, acting as a technical reference and helping raise the engineering standards of the team.
- And, of course, celebrate every success together.
