Description

Define and integrate key data sources (internal UPS data and external datasets) to deliver predictive and generative AI models. Develop and implement robust data pipelines for cleansing, transformation, and enrichment of large, multi-source datasets. Collaborate with data engineering teams to validate and test data pipelines and models during proof-of-concept and production phases. Perform exploratory data analysis (EDA) to identify trends, correlations, and actionable patterns that meet business needs. Design and deploy generative AI solutions, integrating them into analytics and product development workflows. Define and track model KPIs, ensuring ongoing validation, testing, and retraining of models to align with business objectives. Create reusable and scalable solutions through clear documentation, process flows, logs, and clean, well-commented code. Communicate findings through concise reports, data visualizations, and storytelling to both technical and non-technical stakeholders. Present operationalized insights and provide strategic recommendations to business and executive-level stakeholders. Apply best practices in statistical modeling, machine learning, generative AI, distributed computing, cloud-based AI, and performance optimization for production deployment. Leverage emerging tools, open-source frameworks, and cloud technologies (including Vertex AI, Databricks, and IBM WatsonX) to create predictive and prescriptive analytics solutions. Bachelor's degree in a quantitative discipline (e.g., Statistics, Mathematics, Computer Science, Engineering, Operations Research, or related field). Minimum 5+ years of experience in applied data science, machine learning, generative AI, or advanced analytics. Proven experience in building and launching moderate-to-large-scale analytics and AI projects into production. Proficiency in Python, R, and SQL for data preparation, querying, and model development. Strong knowledge of supervised, unsupervised, and generative AI techniques such as regression, classification, clustering, causal inference, and large language models (LLMs). Hands-on experience with GCP Vertex AI, IBM WatsonX, Databricks, or SageMaker, and frameworks like TensorFlow, PyTorch, and Keras. Familiarity with data visualization tools (e.g., Tableau, Power BI, Shiny, D3) to communicate insights effectively. Experience working with Linux/Unix and Windows environments. Familiarity with Java or C++ is a plus. Strong analytical skills with attention to detail and a rigorous problem-solving approach. Ability to translate complex business problems into high-level AI and analytics solutions. Excellent oral and written communication skills, with the ability to explain analytical and generative AI concepts to both technical and non-technical stakeholders. Strong storytelling skills to communicate data-driven insights in a clear, impactful way. Expertise in cloud AI technologies (GCP, IBM WatsonX, AWS, Azure) and modern data pipelines. Demonstrated success in implementing generative AI (LLMs, text-to-image, summarization, conversational AI) for business use cases. Track record of curiosity and innovation, with the ability to explore complex datasets and generate actionable insights. Background in operations research or quantitative social science is a strong plus.
