Technology, Information and Internet Huntington Beach, California 51–200 employees Founded 1978 Privately Held

The Mortgage Office operates a 45-year-old loan management platform serving 1,100+ lenders managing $190B in loans, now undergoing significant technical transformation. The stack reveals a hybrid architecture—C# / .NET backend with SQL Server, transitioning toward modern web (React, Node.js, TypeScript) and AI (LangChain, PydanticAI, Hugging Face, PyTorch). Active projects show two concurrent pushes: legacy data migration and first AI products around loan intake and underwriting. Hiring skews senior-to-mid engineering (7 engineers), suggesting complex modernization work rather than feature velocity.
