Job Description

Senior FullStack Engineer – Integrations Developer

Ubiminds

• Break down large or complex problems into smaller parts, design clean solutions, and implement the core framework. • Build and maintain RESTful APIs and backend services using C#, .NET Core, Entity Framework, and Web API. • Apply software architecture patterns like Domain-Driven Design (DDD) and CQRS to build modular and scalable systems. • Work directly with SQL Server—designing databases, writing stored procedures, optimizing queries, and tuning performance. • Use Entity Framework (EF Core or EF6) for ORM and data access. • Write clean, testable, and maintainable code with proper documentation. • Take full ownership of testing your own code—unit, integration, and performance testing—as part of a Shift Left / No QA team setup. • Collaborate with product managers and other teams to understand requirements and deliver customer-focused features. • Use AI development tools (required)—including GitHub Copilot, Claude, or similar—to assist with code generation, refactoring, documentation, and development speed.

Job Requirements

  • 5+ years of experience in enterprise or SaaS software development.
  • Strong hands-on experience with:
  • C#, .NET Core, Web API
  • Angular or other frontend frameworks.
  • Entity Framework (EF Core or EF6)
  • SQL Server – writing queries, stored procedures, indexing, and performance tuning
  • Solid understanding of object-oriented programming, design patterns, and enterprise architecture.
  • Experience with DDD, CQRS, and clean layering of business logic and data access.
  • Familiarity with multi-threading, asynchronous programming, and system performance tuning.
  • Comfortable with Git and working in a modern development environment (CI/CD, Agile).
  • Strong debugging and troubleshooting skills.
  • Excellent communication skills (written and verbal) in English.
  • Experience working across multiple teams or squads.
  • Required: Active daily use of AI development tools like GitHub Copilot, Claude, or similar in your workflow.

Benefits

  • You are placed in a product-based company, with the same treatment as their full-time employees.
  • Have our full back-office support, from career guidance to HR and concierge services.
  • Enjoy our remote-first policy – we are a distributed team, after all.
  • Get your own MacBook (none of that "bring your own device" stuff here).
  • Have access to growth opportunities with other amazing technology professionals, through tech talks, chapter meetings, and even remote happy hours for tons of fun!
  • Improve your English through free lessons with a native English speaker - get to the next level on your communication skills!
  • Candidate Referral bonus (promote Ubi to your tech friends, and get paid for it!)
  • Miss working in the office? Our cool Florianópolis headquarters is available, whenever you want, with weekly quick massages & tasty snacks, soft drinks, and games
