Job Purpose

To provide technical leadership and architectural direction for the Radius product, driving the design, development, modernization, performance, scalability, and long-term technical evolution of the platform. The role requires deep expertise in .NET and enterprise application development, strong understanding of ERP/business systems, and the ability to work across engineering, product, QA, support, and customer teams to deliver high-quality business solutions.

Core Responsibilities

• Provide technical leadership and architectural direction for the Radius product, ensuring solutions align with product strategy, business objectives, and long-term technology direction.
• Lead the design and development of complex product capabilities using C#, .NET 8 or above, ASP.NET Core, Entity Framework Core, and SQL Server.
• Define and promote scalable, maintainable, secure, and high-performance application architectures and development practices.
• Drive the modernization of the Radius platform, identifying opportunities to improve legacy components, architecture, technology stack, performance, maintainability, and developer productivity.
• Lead technical discussions and architecture reviews, evaluate alternative approaches, and make pragmatic technology and design decisions.
• Work closely with Product Owners and Product Management to understand business requirements, challenge assumptions where appropriate, identify technical implications, and translate business needs into effective technical solutions.
• Provide technical leadership during story refinement, estimation, sprint planning, implementation, and delivery of complex initiatives.
• Act as a technical mentor and provide guidance to Senior Software Engineers and other developers through design reviews, code reviews, technical discussions, and knowledge sharing.
• Establish and promote engineering best practices around clean code, SOLID principles, design patterns, API design, testing, observability, performance, security, and maintainability.
• Design and optimize data access solutions using Entity Framework Core and SQL Server, including complex queries, indexing, data modelling, transactions, and database performance optimization.
• Analyze and resolve complex technical and customer issues, leading root-cause analysis and ensuring that corrective actions address underlying problems rather than only immediate symptoms.
• Support critical customer escalations and work directly with Support, Product Owners, and customers when required to understand issues and drive effective technical solutions.
• Identify product-wide technical risks, architectural limitations, technical debt, and opportunities for improvement, and proactively drive their resolution.
• Establish appropriate unit testing, automated testing, CI/CD, and quality practices to improve product reliability and reduce regression risk.
• Contribute to the evolution of CI/CD and DevOps practices, build automation, deployment processes, and engineering productivity.
• Provide technical guidance on Docker, containerization, cloud technologies, and cloud-native application practices.
• Provide technical guidance for frontend integration and Angular-based applications where required.
• Promote effective use of AI-assisted development tools such as GitHub Copilot and similar technologies to improve engineering productivity, code quality, testing, debugging, documentation, and solution exploration.
• Evaluate new technologies, frameworks, tools, and development approaches and recommend their adoption where they provide measurable value to the Radius product.
• Work across teams and projects to ensure architectural consistency, reuse of common capabilities, and alignment with broader Packaging Suite technology direction.
• Participate in technical planning for major releases, modernization initiatives, customer-driven enhancements, and strategic product investments.
• Prepare and maintain technical documentation including architecture decisions, design specifications, API documentation, technical standards, and implementation guidelines.
• Identify opportunities for automation and process improvement across development, testing, deployment, and support activities.
• Actively contribute to building a strong engineering culture through mentoring, knowledge sharing, technical standards, and continuous improvement.
• Other duties as assigned.

• 10–12 years of hands-on software development experience, with significant experience in enterprise application development using C#, .NET / .NET Core, and ASP.NET Core.
• Strong hands-on experience with .NET 8 or above and modern .NET application architecture and development practices.
• Extensive experience developing RESTful Web APIs, backend services, and enterprise applications using ASP.NET Core.
• Strong expertise in Entity Framework Core, including LINQ, relationships, query optimization, transactions, migrations, and efficient data access patterns.
• Strong expertise in Microsoft SQL Server, including database design, complex SQL queries, stored procedures, indexing, execution plans, performance tuning, and troubleshooting database-related issues.
• Proven experience designing scalable, high-performance, and maintainable enterprise application architectures.
• Strong understanding and practical application of SOLID principles, design patterns, clean architecture, API design, dependency injection, and software engineering best practices.
• Strong experience with unit testing, automated testing, testability, and quality engineering practices.
• Strong understanding of CI/CD, DevOps, build automation, and software delivery practices.
• Experience with Docker and containerized applications and a good understanding of container-based application architecture.
• Experience with cloud technologies and cloud-based application development is desirable.
• Experience with Angular / TypeScript or modern frontend technologies is a plus.
• Experience working with ERP, manufacturing, business management, or other complex enterprise applications is highly desirable.
• Demonstrated experience in technical leadership and architecture, with the ability to influence technical decisions across teams.
• Proven ability to analyze complex technical problems, identify root causes, evaluate alternatives, and drive solutions through to completion.
• Strong experience in application, API, and database performance optimization.
• Experience working with large and/or complex legacy codebases and leading modernization initiatives.
• Strong understanding of software architecture principles, distributed systems, integration patterns, reliability, scalability, security, and maintainability.
• Ability to assess technical debt and establish pragmatic strategies for balancing new feature development, modernization, stability, and technical debt reduction.
• Proficiency in using AI-assisted development tools effectively for coding, code analysis, debugging, testing, documentation, and technical problem solving.
• Ability to quickly understand complex business domains and translate business requirements into robust technical architectures and solutions.
• Strong ownership and leadership mindset, with the ability to work independently and take accountability for technically complex initiatives.
• Ability to influence and collaborate effectively without relying solely on formal authority.
