Our cloud\-native SaaS platform digitizes paper\-based processes, accelerates cash flow for carriers and shippers, and drives operational efficiency across the freight ecosystem. Trusted by thousands of carriers and brokers, Transflo processes billions of dollars in freight payments annually. Every engineer at Transflo ships software that real customers depend on every day. **Role Overview** We are looking for a Senior .NET Software Engineer who thrives in a dual\-mode environment: maintaining and methodically retiring a mature .NET/C\# codebase while simultaneously building out a modern cloud\-native replacement. This is not a greenfield\-only role, nor a pure legacy\-support role—it requires equal comfort in both worlds and the judgment to know when to stabilize, when to migrate, and when to rebuild. You will join a cross\-functional product engineering team focused on workflow automation products that power document capture, load management, and payment processing for transportation and logistics customers.
