Mortgage servicing and originations platform for homeowners

Financial Services Dallas, TX 5,001–10,000 employees Public Company

Mr. Cooper operates a mortgage servicing and originations business at scale (5,001–10,000 employees, public on NASDAQ). The tech stack is enterprise-heavy—C#/.NET Core, Azure, SQL Server, Oracle—with distributed compute (Kubernetes, Docker) and observability (Splunk, New Elasticsearch). Active projects center on loan onboarding, platform retirement, and IVR/branding standardization, while pain points cluster around operational outages, vendor cost management, and reconciliation workflows—typical friction points in legacy financial-services infrastructure.
