What are the responsibilities and job description for the Data Scientist position at Optimize Search Group?
Title: Data Scientist
Location: Dallas
Duration: Direct Hire
The Senior Data Scientist supports the development, maintenance, and enhancement of analytics and predictive modeling for small business lending. This role requires practical, production-focused experience with real-world datasets and a strong balance of technical execution, business impact, and ownership mentality.
This is not a research-oriented role. The ideal candidate is highly hands-on and comfortable performing deep data cleaning, feature engineering, data manipulation, and model development in fast-paced production environments.
The Senior Data Scientist partners closely with Credit, Risk, and Engineering teams to build and maintain production-ready credit risk and fraud detection models that support lending decisions. This individual is responsible for preparing complex datasets, developing predictive models, and delivering accurate, high-quality analytical outputs that inform underwriting and portfolio strategy.
Success in this role requires strong AI-driven thinking, attention to detail, proactive problem-solving, and the ability to independently drive projects from exploration through deployment and ongoing monitoring.

- Develop and maintain production-ready credit risk, fraud detection, and predictive models that support small business lending decisions.
- Clean, transform, and prepare large, complex datasets for modeling and analysis.
- Work with diverse data sources including business credit bureau data, bank transaction data, financial statements, and alternative datasets.
- Apply AI-driven approaches to improve modeling efficiency, automate workflows, and enhance model performance.
- Deliver high-quality analytical outputs that directly support underwriting and credit strategy.

- Collaborate effectively with Credit, Risk, Product, and Engineering stakeholders to deliver scalable analytical solutions.
