This role requires strong software design skills, practical application of SOLID principles and design patterns, effective use of AI-assisted/code-generation tools, and the ability to mentor other engineers and raise engineering standards across the team. Essential Responsibilities: Design and develop scalable, secure, maintainable applications using C#, modern .NET Core, REST APIs, React, microservices, and micro frontend architectures. Translate business and product requirements into effective technical designs, APIs, services, components, data models, and integration solutions. Apply SOLID principles, clean architecture, separation of concerns, dependency injection, domain-driven design concepts, and appropriate software design patterns. Design services with appropriate boundaries, minimizing coupling while supporting independent development, testing, deployment, and scaling. Build and deploy applications in a cloud environment, using cloud-native services, containers, CI/CD, configuration management, logging, monitoring, and observability Develop and integrate RESTful APIs, asynchronous messaging/events, and third-party/external system integrations. Navigate the iterative development and release management processes within the Scrum framework. Collaborate closely with Product Managers, Tech Leads, Architects, QA, DevOps, application support, security, and other engineering teams in an Agile/Product Operating Model Mentor junior and mid-level developers in software design, coding standards, debugging, testing, AI-assisted development, and engineering best practices. Troubleshoot complex production issues, perform root-cause analysis, and implement sustainable corrective and preventive solutions. Develop and maintain comprehensive technical documentation. Take ownership of assigned capabilities from technical design through development, testing, deployment, production validation, and ongoing support. Qualifications: Bachelor’s degree in Computer Science, Information Technology, or Engineering (or equivalent experience). Typically, 10+ years of professional software development experience, with substantial hands-on experience developing enterprise applications using C# and .NET. Strong experience designing and developing full-stack enterprise applications rather than primarily maintaining existing applications. Demonstrated ability to independently take a complex requirement from analysis and technical design through implementation and production deployment. Excellent communication (written & verbal), knowledge sharing, and collaboration skills. Experience within team environments and Agile project methodologies is a must. Technical Expertise: Strong hands-on expertise with C#, modern .NET Core, ASP.NET Core, Web API, RESTful services, dependency injection, asynchronous programming, LINQ, Entity Framework/EF Core, and enterprise application development. Strong experience with React, JavaScript/TypeScript, HTML5, CSS, component-based development, state management, API integration, and modern frontend development. Experience with micro frontends is strongly preferred. Demonstrated ability to design applications using SOLID principles, clean code, design patterns, layered/clean architecture, microservices, API-first design, event-driven concepts, domain modeling, resiliency patterns, and loosely coupled architectures. Experience developing and operating applications in a public cloud environment—Azure preferred—including CI/CD pipelines, containers, cloud services, application configuration, secrets management, monitoring, logging, and observability. Strong SQL/PLSQL and relational database skills, preferably SQL Server, along with experience designing data access layers, integrations, APIs, messaging/event-based integrations, and performance-efficient database interactions. Maintain a solid understanding of security practices, including authentication and authorization services. Strong experience with automated unit testing, mocking, integration testing, API testing, code-quality practices, static analysis, secure coding, and automated quality gates. Create, update, and enhance Stored Procedures, SSRS reports, and SSIS packages. Demonstrated ability to effectively use generative AI and code-generation tools throughout the SDLC—not simply generate code—including requirement clarification, technical design, implementation, refactoring, test generation, debugging, documentation, and PR/code review.
