Staff AI Engineer

Job Description Staff AI Engineer Mission Design and deliver trustworthy AI systems, machine-learning solutions, data products, and applications that improve decisions, automate work, and create measurable business impact across Sales, Service, Marketing, and Global Markets. This is a hands-on Staff AI Engineer role for an experienced individual contributor who can move from business problem framing and analytical discovery through data engineering, model and AI-system development, application delivery, and production operation. The role combines practical data science with strong software and platform-engineering skills to build reusable, secure, maintainable, and adopted AI capabilities at scale. Key Responsibilities Applied AI and Machine Learning Translate ambiguous business problems into clear AI objectives, solution strategies, evaluation plans, and measurable success criteria. Develop, validate, and improve predictive, forecasting, classification, segmentation, optimization, natural-language, generative-AI, and decision-support solutions. Select practical statistical, machine-learning, and AI techniques based on the business decision, available data, operational constraints, risk, and expected value. Apply methods such as experimentation, time-series forecasting, causal analysis, retrieval-augmented generation, agentic workflows, or other modern AI patterns when they are fit for purpose. Partner with stakeholders to identify when AI is appropriate—and when simpler analytics, rules, or workflow automation will create better outcomes. Data and Feature Engineering Define data requirements and partner with data engineering, platform, and business teams to establish reliable, documented data sources. Build scalable ingestion, transformation, aggregation, feature, embedding, and knowledge pipelines using batch or streaming patterns as appropriate. Create reusable data products, analytical datasets, semantic models, feature assets, and retrieval indexes that support multiple use cases. Perform exploratory analysis, data-quality assessment, schema validation, feature selection, leakage detection, and data-availability analysis. Work across structured and unstructured data, including customer, vehicle, dealer, sales, service, warranty, incentive, document, conversation, and operational datasets. AI Application and Platform Engineering Build production-grade AI applications, services, APIs, assistants, dashboards, and workflow tools that make AI capabilities accessible to end users. Translate models and AI systems into intuitive user experiences, decision-support tools, automation workflows, and self-service capabilities. Design clean interfaces between data pipelines, models, foundation models, tools, backend services, and front-end or workflow applications. Implement retrieval, grounding, tool use, orchestration, prompt management, evaluation, and human-in-the-loop patterns where appropriate. Develop secure, testable, observable, and maintainable software using sound engineering practices, code review, version control, and automated testing. Partner with architects and software engineers on application structure, integration patterns, authentication, authorization, deployment, and operational support. Evaluation, Reliability, and Production AI Establish evaluation frameworks that reflect real-world business outcomes, not only offline technical metrics. Assess model and AI-system quality, calibration, bias, interpretability, robustness, factuality, groundedness, safety, usability, latency, and operational fit. Design and analyze experiments, pilots, red-team exercises, and champion/challenger approaches to validate value and manage risk before broad adoption. Deploy solutions as APIs, batch processes, scheduled workflows, app
