Data Scientist

Position Summary

The Data Scientist supports Credit Union of Texas's vision to be the trusted financial partner for our members and our community by applying statistical, machine learning, and data engineering techniques to credit union data. Working within the Finance function and partnering broadly across the organization, the role develops dashboards, reports, predictive models, and analytics that inform financial forecasting, member experience, marketing effectiveness, and operational decisioning. The Data Scientist collects and integrates operational and market data, identifies trends and variances against forecast, designs and validates models, and operationalizes analytics in partnership with business stakeholders. The role uses CUTX-approved AI and machine learning tools under defined governance, with mandatory human-in-the-loop review on any model output that influences member or financial outcomes.

• Build and maintain data pipelines, queries, and reusable analytic assets using SQL, Python, R, or other CUTX-approved tools.

Model Validation & Monitoring

• Develop and operate an A/B testing framework and test model quality before and after deployment.
• Coordinate with functional teams to implement models in production and monitor outcomes against expected performance.
• Develop processes and tools to monitor model performance, data quality, drift, and accuracy over time, and document validation results.

Governance, Documentation & Collaboration

• Document model purpose, data inputs, assumptions, limitations, validation results, and intended use consistent with CUTX model risk and AI governance expectations.
• Coordinate across Finance, Marketing, Lending, Risk, IT, and Compliance to align analytic work with enterprise priorities.

Core Competencies

Competency

Proficiency Level

Why This Matters in This Role

AI Literacy

Advanced

The role builds, evaluates, and operationalizes AI/ML models (Tier 2) and is expected to recognize when a use case escalates to Tier 3, apply appropriate controls, and ensure human-in-the-loop review.

Analytical Rigor

Advanced

The role is responsible for the statistical and methodological soundness of models that inform financial and member-impacting decisions.

Risk Awareness

Advanced

Model error, bias, or misuse can produce direct member harm, fair lending exposure, or financial loss; the role must identify and escalate model risk.

Member Centricity

Intermediate

Models influence member experience, targeting, and outcomes; design choices must reflect fair treatment and CUTX member values.

Communication

Advanced

The role must translate complex statistical and ML concepts into clear, decision-ready narratives for executives and cross-functional partners.

Operational Discipline

Intermediate

Models, code, and documentation must be reproducible, version-controlled, and audit-ready to meet model risk and AI governance expectations.

Compliance Orientation

Intermediate

Analytic work must respect Fair Lending, UDAAP, GLBA data protection, and TRAIGA-aligned AI governance constraints.

AI & Technology Expectations

AI-Augmented Workflows

The following workflows are AI-augmented in this role. The Data Scientist is expected to work fluently within these workflows, exercise sound judgment over AI outputs, and follow all applicable controls.

• Predictive and statistical model development for financial forecasting, member behavior, and product performance.
• Machine learning model design, training, validation, and monitoring on CUTX data.
• AI-assisted code generation, query authoring, and analytic prototyping using CUTX-approved tools.
• Automated data quality checks, anomaly detection, and model drift monitoring.
• AI-assisted summarization of analytic findings and drafting of stakeholder-facing narratives.

AI Tier and Human-in-the-Loop Responsibility

This role operates in AI Tier 2 for its principal AI-augmented workflows (see Appendix A). The Data Scientist retains accountability for any decision, communication, or member/employee-impacting action influenced by AI output, consistent with the CUTX Generative AI Usage Policy §3.4.

The Data Scientist is required to:

• Apply human-in-the-loop review on every model output, recommendation, or analytic finding that informs a member-impacting or material financial decision before it is acted upon.
• Validate AI-assisted code, queries, and analytic artifacts before they are used in production or shared with stakeholders.
• Escalate to the CIO and the AI Council any use case that involves direct member-impacting decisioning, automated adverse action, or regulated decisioning, which is treated as Tier 3 and requires additional controls.
• Stop reliance on AI or model output and escalate immediately if the output appears inaccurate, biased, non-compliant, or outside the role's documented scope (Generative AI Usage Policy §3.5).
• Refrain from entering member non-public personal information (NPI), confidential CUTX information, or material non-public information into any AI tool not explicitly approved for that data classification.
• Complete all required AI training within thirty (30) days of hire and maintain annual currency.

Approved AI Tools

The role is approved to use the following AI tools in performing essential functions (subject to the Generative AI Usage Policy and any tool-specific guidance issued by the AI Council):
