• Work closely with product managers and frontend engineers on API and workflow design

• 6+ years of backend engineering experience
• Strong expertise in C# and .NET
• Experience designing production-grade REST APIs and backend workflows
• Strong understanding of clean architecture and separation of concerns
• Deep experience with Entity Framework, SQL, and relational databases
• Experience handling concurrency, idempotency, and transactional consistency
• Experience with Azure and/or AWS cloud platforms and distributed microservices architectures
• Strong debugging, architecture, and problem-solving skills
• Fluency in English

Nice to Have:

• Experience in banking, fintech, CRM, or customer onboarding platforms
• Experience with matching engines, orchestration workflows, or distributed systems
• Experience mentoring engineers and leading technical initiatives
• Fluency in Portuguese
