The Engineer II, ML & AI Engineering role at CarMax is responsible for building and operating scalable machine learning and AI capabilities across the organization. You will partner closely with Data Scientists to productionize models and develop reliable inference services, with a focus on testing, monitoring, scalability, and operational excellence. This role plays a key part in delivering resilient, high-performing AI and ML solutions that power critical business and customer experiences.

We are looking for an engineer with a strong foundation in software and cloud engineering who is passionate about transforming machine learning and AI innovations into mission-critical, high-visibility capabilities that support CarMax's iconic customer experience.

Essential Responsibilities:

• Build and maintain production machine learning capabilities spanning feature engineering, training, evaluation, deployment, and model inference supporting initiatives across the organization, with attention to latency, throughput, and cost

• Design and build agentic AI systems, including tool use, orchestration, memory, and the evaluation harnesses and observability needed to run them reliably in production.

• Own the operational health of production ML and agentic systems: monitoring and alerting for model performance, data drift, and prediction quality, plus on-call incident response end to end and the follow-through that prevents repeat failures

• Collaborate with Data Scientists to translate experimental work into tested, maintainable, production-grade code.

• Partner with engineering and product teams to turn machine learning models into mission-critical, high-visibility capabilities that support CarMax's iconic customer experience

• Demonstrates a passion for Data Science and Machine Learning, continuously driving innovation and improvement in these domains.

• Proficiency in a programming language such as Python, Java, or C#, and hands-on experience with ML frameworks such as PyTorch or TensorFlow

• Working knowledge of distributed databases (e.g., DynamoDB, Cosmos DB), caching systems, and vector databases, with experience applying them to high-throughput, low-latency production workloads

• Excellent communication skills, with the ability to adapt messaging to technical and non-technical audiences

• Experience on a fast-paced, highly collaborative agile team within a product-oriented organization

Preferred Qualifications:

• Agentic development workflows: Comfortable using AI coding agents to plan, implement, test, and review software, along with sound judgment about where agent-generated work requires human verification

• MLOps practices: experiment tracking, model registries, reproducible training, and CI/CD or automated retraining for ML (MLflow, Azure ML, SageMaker, Kubeflow, or equivalent)

• Experience with model serving platforms and real-time inference (Azure ML endpoints, Databricks, SageMaker, or equivalent)

• Experience designing or operating microservices and distributed architectures (containers, Kubernetes, service-to-service APIs)
