[Job-20798] Senior Data Scientist, Colombia We are tech transformation specialists, uniting human expertise with AI to create scalable tech solutions. With over 6,500 CI&Ters; worldwide, we have built partnerships with more than 1,000 clients over our 30 years of history. Artificial Intelligence is our reality. When applying for one of our positions, you agree to the use of AI in the early phases of the selection process, where your profile will be evaluated by our virtual assistant. For more information, visit our opportunities page. Role Overview CI&T; is seeking an experienced Data Scientist to join our nearshore team working on a project for our client in the mortgage technology sector. This role focuses on analyzing patterns in third-party API usage and developing algorithms to optimize the sequence and decision-making around these API calls. You will work with verification services to create intelligent "waterfall" strategies that minimize unnecessary calls while maintaining verification effectiveness. Your work will impact cost efficiency and processing speed in mortgage verification workflows. Key Responsibilities 1. Analyze historical patterns of third-party API usage in verification processes (income, employment, assets). 2. Develop statistical models and algorithms to optimize the sequence and necessity of API calls. 3. Create intelligent "waterfall" strategies to minimize expensive API calls while maintaining verification quality. 4. Build predictive models to determine when verification services are likely to provide value versus cost. 5. Design algorithms for real-time decision-making on verification service calls based on available data. 6. Quantify and track cost savings achieved through API call optimization. 7. Collaborate with engineers to implement models and algorithms into production systems. 8. Develop metrics and KPIs to measure efficiency gains and cost savings. 9. Work with stakeholders to understand verification requirements and translate them into optimization strategies. 10. Research and implement machine learning techniques to enhance decision-making around third-party services. Required Qualifications - Solid experience in data science or machine learning roles. - Experience with optimization algorithms and decision trees. - Proven track record of cost optimization through data analysis. - Experience analyzing API usage patterns and creating efficient workflows. - Strong knowledge of statistical analysis, probability, and experimental design. - Advanced or fluent English communication skills (written and verbal) for remote collaboration. Preferred Qualifications - Experience with optimization problems, especially cost/resource optimization. - Knowledge of decision theory and sequential decision-making. - Familiarity with financial verification processes or systems. - Background in operations research or similar analytical fields. - Programming skills in Python and experience with ML libraries (scikit-learn, TensorFlow, PyTorch). - Experience with AWS services (SageMaker, Lambda, S3). - Experience with A/B testing and experimental design. - Knowledge of data ethics and privacy considerations. - Previous experience working with international teams. - Understanding of balancing business rules with cost optimization. If interested, just apply and good luck!
