We are building a Chief Software Engineer (.NET / AWS) role to steer the design and modernization of mission-critical applications at scale. You will lead a cloud-native shift to AWS event-driven architectures using C# (.NET 8/9) and React while guiding migration from .NET Framework 4.8 on ASP.NET/IIS. You will set architectural direction, deliver secure RESTful APIs, codify infrastructure with IaC, and coach engineers—apply now
