Guidance Residential, LLC is a strong, growing company that specializes in residential mortgage lending. Our team members are a vital strength in our ability to grow and continue to serve our customers.
We are seeking an experienced Application Developer to support and extend our mortgage loan origination platform (Integra EPIC LOS). Reporting to the Hiring Manager and working under the direction of our Lead Application Developer, this role designs, builds, and maintains LOS configurations, system integrations, and reporting/analytics that keep our lending operation running efficiently and in compliance.

- Coordinate work across the team and with business stakeholders and vendors; communicate status, risks, and dependencies clearly.
- Break large initiatives into workable, well-sequenced tasks.
- Follow SDLC and coding best practices: standards, peer code review, testing, and disciplined change control.
- Use industry-standard source/version control and team collaboration tooling for all work.
- Produce and maintain clear technical and functional documentation — specifications, data dictionaries, runbooks, and user guides.
