Financial Services São Paulo 501–1,000 employees Founded 2015 Partnership

FitBank is a Central Bank-authorized neobank operating on a B2B2X model, offering white-label financial infrastructure to corporate clients across payments, lending, and capital markets. The tech stack is split between .NET/C# backend (SQL Server, MongoDB, RabbitMQ) and modern frontend layers (React, Vue), deployed on AWS and GCP with Kubernetes orchestration—a pattern matching their stated pain points around multicloud scalability and cost optimization. Engineering-heavy hiring (50% of open roles) focused on mid-to-senior levels, paired with active infrastructure projects (DevOps CI/CD, observability, IaC automation, container orchestration), signals FitBank is scaling operational maturity to support regulated, multi-geography expansion beyond Brazil.
