About Applied Business Software, Inc.

Applied Business Software, Inc. (ABS), the maker of The Mortgage Office®, is the industry leader in private lending and loan management technology. Since 1978, our software has powered thousands of lenders, including private money firms, municipalities, CDFIs, Tribal Nations, universities, franchisors, third-party servicers and other non-bank lenders, helping them streamline, automate, and scale their lending operations with confidence.

This is a senior individual contributor role focused on building customer-requested functionality, integrations, and data solutions using C#, .NET, and SQL Server.

While execution-focused, this role also offers the opportunity to help establish and mature our Professional Services development function — including contributing to development standards, reusable patterns, documentation, and technical processes as the team grows.

It is best suited for someone who enjoys hands-on development, clear direction, and the chance to help shape how work is delivered, without people management or product ownership.
