Senior Software Engineer - .NET | Dynamics | Sharepoint | Dev & App Support
📍 Sydney CBD (Hybrid) | Long-term contract

This role defines full-stack Microsoft engineering with a strong focus on application support, custom development, and platform stability. From building out new functionality in .NET and Azure - to maintaining the complex integrations and Dynamics 365/CE-based business applications that power the organisation - you'll work across every layer of delivery.

You'll join a lean, high-impact team inside a large and complex enterprise. It's the kind of environment where your code and your troubleshooting skills both matter - and where you'll be trusted to own application health, performance, and continuous improvement end-to-end.

🛠 What you'll work with:
* .NET Framework & .NET Core - app logic, integrations, legacy support
* C# - backend services, REST APIs, logic layers
* MS SQL Server - core enterprise database
* BizTalk Server - current primary enterprise integration layer
* Dynamics 365 / CE & SharePoint - critical business platforms you'll support and extend
* Azure App Services & Logic Apps - cloud-native builds and workflow automation
* Azure DevOps - CI/CD and repo management
* ReactJS - in play on newer front-end builds

✅ What you'll be doing:
* Maintain and support core applications across both custom code and OTB platforms
* Build new features and integrations in .NET, Azure, and Dynamics
* Investigate, troubleshoot, and resolve issues in production systems
* Collaborate closely with Tech Leads and BAs to shape technical outcomes
* Uphold quality through structured testing, documentation, and peer reviews

💡 Why this role:
* Core Microsoft stack work with strong application ownership
* Deep involvement across support, build, and integration
* Contract role with the longevity of perm - 5+ year programs
* Sydney CBD base with hybrid flexibility (Weds anchor day)

📍 Location: Sydney CBD (Hybrid)
