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).

• Perform ad‑hoc data analysis, translate business questions into data models and metrics, and validate data quality.
• Partner with stakeholders to define KPIs and deliver actionable, trustworthy reporting.
• Act as lead on assigned projects: gather and document requirements, define scope, size and estimate effort, build timelines, and manage deliverables to completion.
• 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.

Best Practices, Documentation & Governance

• 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.
