Job Title
Senior Dot Net Developer
Job Description
Professional Experience
Candidates should have 6 to 8 years of hands-on experience in the .NET ecosystem, focusing on backend development and architecture.
Technical Skills
•Proficiency in C#, .NET (Core), RESTful API design, and SQL is essential for building scalable, integrated services.
•Experience with PostgreSQL, including the pgvector extension for AI/ML vector operations, is a plus.
•Experience working with .NET 10 and knowledge of its new features is an advantage.
•Knowledge of logging and monitoring mechanisms, including OpenTelemetry for distributed tracing, metrics, and observability, is highly valuable.
Cloud and Development Patterns
•Familiarity with Azure services and modern development patterns like REPR supports cloud deployment and maintainable code.
•Understanding of scalable architectural patterns such as:
•CQRS (Command Query Responsibility Segregation)
•DDD (Domain-Driven Design)
•EDA (Event-Driven Architecture)
•Multi-tenant application architecture
Quality and Productivity
•A quality-driven mindset with experience using AI-assisted tools enhances clean code and advanced developer productivity.
Business Logic Migration
•Migrate and refactor existing business logic currently spread across multiple repositories into a modern, domain-driven architecture (DDD).
•Rebuild the core system of the Smartenance SaaS platform using .NET in a scalable, modular, and maintainable structure.
•Ensure functional parity with the legacy system while improving maintainability, testability, and domain clarity.
API Design and Integration
•Design and implement a single unified API that serves all platform services, replacing fragmented legacy interfaces.
•Follow an OpenAPI-first approach, defining specifications upfront to ensure consistency, reusability, and clear contracts between teams.
•Integrate existing logic into the new service layer.
•Build secure, high-performance API endpoints that integrate seamlessly with internal and external systems.
Authentication & Security
•Implement and maintain PingOne authentication and authorization within the new unified API architecture.
•Support migration from Azure AD–based authentication to PingOne, ensuring secure identity flows, seamless user access, and minimal disruption during transition.
•Ensure all API endpoints follow enterprise-grade security standards, including token validation, claims-based access, and secure session handling.
Database Development
•Design and implement robust relational database structures with clean domain- and tenant-level separation to ensure performance, scalability, and reliability.
•Support migrations from legacy database structures(Azure SQL and CosmosDB) into the new domain-aligned model in PostgreSQL.
