• Mentor and review the code of other developers
• Contribute to the architectural direction of the system

Required Experience

• Expert-level C# .NET knowledge (C#, ASP.NET) with several years of commercial C# .NET development experience

• Good development practices — test automation, IoC, SOLID principles, observability, logging and monitoring with Grafana or similar
