About the Role
We are rebuilding and modernizing Solvace's backend from the ground up. This role sits at the core of our platform transformation and is ideal for a senior backend engineer who enjoys building complex user interfaces, making sound architectural decisions, and delivering high-quality, maintainable code.
You will work closely with frontend, QA, and product teams in a cross-functional squad, helping shape a fast, scalable, and professional user experience used by global industrial clients.
This is not a plug-and-play role. We are looking for engineers who think deeply about UI architecture, performance, and long-term maintainability.
Your Mission
* Build and evolve backend APIs and services with .NET Core 8, C#, and PostgreSQL/SQL Server
* Design for performance, observability, and global scale
* Work closely with frontend, QA, and product teams in agile squads
* Write clean, tested, and maintainable code, with attention to security and resilience
* Help shape architectural patterns and review code across the squad
* Champion code quality through clean architecture, peer reviews, and scalable design patterns, supported by our Definition of Done and SonarQube standards
* Collaborate in a culture that values engineering discipline, automated testing, and continuous improvement across the SDLC
Requirements
* 5+ years of experience in backend development, preferably in SaaS environments
* Strong knowledge of .NET Core (v6+ preferred) and RESTful API design
* Comfortable with SQL and NoSQL data modeling
* Experience with DevOps, Git, CI/CD, and agile delivery
* Clear understanding of modular architecture and versioning for B2B solutions
* Fluent Portuguese (spoken and written)
Nice to Have
* Experience with AWS, containerized infrastructure (e.g., ECS, Lambda)
* Familiarity with MS ecosystem and cloud cost-aware design
