About the role

Key responsibilities & impact

Architect and build a .NET chassis that abstracts cross-cutting responsibilities for product teams:
Database persistence and migrations
Publishing and consuming events via messaging
Distributed observability (structured logs, metrics, tracing)
Authentication and authorization integrated with the corporate identity provider
Resilience patterns (retries, circuit breaker, rate limiting)
Test framework with real infrastructure (integration and architecture)
Ensure a new service based on the chassis can be configured and deployed in under 2 hours
Serve as the technical reference for stream-flow teams during incremental migrations (Strangler Fig)
Work side-by-side with the Digital Account team, which will become the company’s .NET reference team

Requirements

What you’ll need

Active use of AI-assisted programming tools (Claude Code, Cursor, GitHub Copilot or similar) in daily work — not as a curiosity, but as part of the development workflow
Experience modernizing legacy systems using the Strangler Fig pattern — incremental migrations without a big-bang rewrite
Experience working in or leading a Platform team (building a chassis, archetypes, enabling other teams)
Deep knowledge of Ruby — even if not your everyday language; the monoliths you will decompose are Rails apps, and understanding their patterns and pitfalls is essential
Genuine polyglot profile: proficiency in multiple languages with the ability to move across paradigms
Solid understanding of distributed software architecture (events, messaging, resilience, observability)
Experience with modern .NET — ideally someone who knows Ruby from their background and uses .NET today
Experience with an opinionated microservices chassis or framework (Spring Boot, .NET, etc.) as a conceptual reference
Experience in PCI DSS environments and/or regulated sectors (BACEN, Open Finance)
Knowledge of cloud infrastructure (AWS or GCP) and container/Kubernetes practices
