Decision Platforms Engineer

Republic Finance, LLC • Plano, TX • 1d ago

Overview & Responsibilities

In business for more than 70 years, Republic Finance is proud to be a trusted lender in over 300 communities across the United States! We specialize in providing flexible lending solutions and outstanding customer service. Driven by our shared mission to pursue excellence for our team, our customers, and our performance, we are continuously improving our customer offerings in tandem with opening more branches in new states each year. We also regularly promote from within and enjoy giving back to the communities we serve. In a nutshell, our company culture is about helping customers, investing in our employee's future, and ensuring that our performance makes an impact on our community!

Republic Finance is seeking a technically strong, detail-oriented professional to join the Fraud and Decision Platforms team. In this role you will be the hands-on builder behind our credit, underwriting and fraud decisioning - translating business policy into configured, tested and governed logic inside our decision platforms, and connecting those platforms to the data vendors, bureaus and internal systems that feed them. This role reports to the Manager of Fraud and Decision Platforms and will be based out of our Plano, TX HQ on a hybrid schedule. Key responsibilities are as follows:

Implement credit, underwriting and fraud policies within the decision platforms, translating business requirements into decision flows, rulesets, scorecards, matrices and cutoff logic.

Deploy machine learning models produced by the Data Science team into the decision platforms - via PMML, native scorecard logic, or API calls to externally hosted model endpoints - and validate that in-platform scoring reproduces the model owner's expected results.

Coordinate with data vendors, credit bureaus and solution partners to build and maintain connectors that enable API-driven decisioning, including request and response mapping, attribute parsing, authentication, and timeout and fallback handling.

Partner with business teams to ensure requirements are clear, complete and testable before development begins; document decision logic, assumptions and edge cases so that changes are reviewable and auditable.

Develop a comprehensive understanding of Republic Finance's business systems - loan origination, servicing and data platforms - and how the decision engine interacts with them end to end.

Build and maintain robust governance processes, including version control, change management, peer review, release documentation and rollback procedures, so the decision platforms run reliably and every production change is traceable.

Perform thorough testing before any production release, including unit, regression, integration and user acceptance testing, using Postman and other automated testing or simulation software; build reusable test case libraries and batch simulations to confirm expected decision outcomes.

Monitor changes post-implementation - tracking decision volumes, approval rates, error rates and response times - and confirm the agreed business success criteria are met before closing out a change.

Troubleshoot production decisioning issues, perform root cause analysis, and implement preventive controls and monitoring to reduce recurrence.

Requirements

Bachelor's degree or equivalent experience in a quantitative or technical subject area is required, an advanced degree is attractive. Extensive experience and skills in Decision Platforms can waive the requirement for a degree.

1-3 years of professional experience programming, working with databases, and configuring or supporting Decision Platforms such as those from GDS Link Modellica, Provenir, FICO, Experian PowerCurve or comparable rules and decisioning engines. Consumer lending or financial services experience strongly preferred.

Intermediate to Advance knowledge of SQL, Snowflake and relational databases.

Intermediate to Advance knowledge of programming using Python.

Intermediate to Advance knowledge of Excel and BI skills; Power BI preferred.

Working familiarity with REST APIs and JSON or XML payloads, and experience using Postman or similar tools for API testing.

Excellent analytical and problem-solving skills, with strong attention to detail and a strict, test-first approach to production changes.

Excellent communication and should be a standout colleague willing to collaborate and help other team members.

A high level of initiative, intellectual curiosity and creativity, and strong time management skills with the ability to lead multiple concurrent releases.

Preferred Qualifications:

Experience deploying machine learning models into a production decisioning environment.

Familiarity with credit bureau data and attributes (Experian, Equifax, TransUnion) and with third-party fraud or identity verification vendors.

Exposure to model risk management, fair lending, or ECOA/Regulation B adverse action requirements as they apply to automated decisioning.

Experience with version control (Git) and structured release management or CI/CD practices.
