Challenge
We’re looking for a hands-on Senior .NET Engineer to help design, build, and deliver high-quality, scalable enterprise SaaS applications. This role is ideal for someone who enjoys solving complex problems, writing clean code, and taking full ownership of their work—including testing and quality.
Responsibilities:
- 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.
Mandatory Skills:
- 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.
Nice to Have:
- Real-world experience building AI-powered features (e.g., smart forms, intelligent search, NLP features).
- Experience working in a Shift Left environment with full feature ownership—design to production.
- Exposure to event-driven architecture or messaging patterns.
