• Technical responsibility: You will develop and further evolve complex backend and frontend components based on Java (Spring Boot) and TypeScript (Vue.js). • System architecture: Actively shape the architecture of our platform — modular, scalable and maintainable. • Feature ownership: Take responsibility for entire feature areas, from the initial architecture design to operation in production. • Sustainable code quality: Drive refactoring initiatives, design migrations and consistently improve existing modules. • Engineering culture: Contribute to our development processes — through automated tests, clean CI/CD pipelines, meaningful code reviews and practical tools. • Cross-functional collaboration: Work closely with UX, Product and DevOps — always with a focus on the best overall outcome.

• Develop and maintain backend services and APIs using C# and ASP.NET Core. • Support the implementation of microservices and integrations, following established architectural patterns. • Build and maintain RESTful APIs and contribute to event-driven integrations (Azure Service Bus). • Implement background processing tasks using Azure Functions or similar tools. • Work with Azure SQL and Entity Framework Core for data access and persistence. • Follow coding standards and contribute to clean, maintainable, and testable code. • Apply security practices using authentication and authorisation standards (OAuth2/OIDC, JWT). • Contribute to CI/CD pipelines and support deployment processes. • Troubleshoot issues using logs and basic monitoring tools. • Collaborate with team members and participate in code reviews and technical discussions.

• Design, build, and maintain backend microservices and integrations using .NET 8/9 and ASP.NET Core within a CQRS + Clean Architecture ecosystem. • Contribute to solution design, making informed trade-offs around performance, scalability, and maintainability. • Develop RESTful APIs (command/query separation) and integrate systems using event-driven patterns (Azure Service Bus). • Implement and maintain background processing using Azure Functions and message-driven workflows. • Work with Azure SQL and Entity Framework Core, including data modeling and query optimization. • Apply structured patterns to ensure code quality, maintainability, and consistency. • Follow and contribute to security best practices using Azure Entra ID (OAuth2/OIDC, JWT). • Contribute to CI/CD pipelines (Azure DevOps) and support containerized deployments (Azure Container Apps). • Troubleshoot production issues using Application Insights, logs, and distributed tracing. • Collaborate with cross-functional teams and participate in technical discussions and design reviews. • Support knowledge sharing and help mentor less experienced engineers.

• Lead the strategic planning, design, and modernization of the .NET application development and production architecture. • Define and execute the transition from legacy ASP .NET Framework environments to modern platform, while ensuring both environments remain stable, secure, and fully supported throughout the lifecycle. • Ensure alignment with enterprise technology strategies and seamless integration with network architecture and complementary development platforms. • Oversee and administer both legacy and future development and production environments, including installing, configuring, upgrading, securing, and optimizing frameworks, toolsets, and pipelines. • Provide technical leadership through training, coaching, and mentoring IT&R staff on modern design, development patterns, and migration strategies, while also supporting ongoing work within the legacy environment.
