Job description

About Yum!

Our story might surprise you. We are the world’s largest restaurant company, encompassing KFC, Taco Bell, and Habit Burger & Grill, but there is much more happening behind the scenes than frying chicken, baking pizzas, and serving tacos.

We connect customers with our brands through apps, websites, kiosks, point-of-sale systems, and other digital dining experiences. Behind those experiences is a growing ecosystem of data, artificial intelligence, and machine learning solutions that support restaurant operations and customer engagement around the world.

Job Summary

We are seeking an experienced AI Support Engineer with a Machine Learning Engineering focus to join our 24/7 AI operations team.

This role is responsible for supporting, maintaining, and improving production machine learning platforms, pipelines, APIs, and deployment environments. The engineer will independently investigate complex operational issues, coordinate incident response, and partner with Machine Learning Engineers, Data Scientists, AI Engineers, platform teams, and cloud engineering teams to restore service and improve system reliability.

In addition to responding to incidents, this role will help strengthen the operational maturity of our AI ecosystem by developing automation, improving observability, refining support processes, and identifying recurring issues that should be addressed through engineering changes.

The successful candidate will have hands-on experience supporting cloud-based production systems and will be comfortable operating across machine learning, infrastructure, software engineering, and DevOps domains.

Key Responsibilities

Production Operations and Reliability

• Monitor and support production machine learning pipelines, inference services, APIs, feature-processing workflows, and deployment environments.
• Independently diagnose and resolve moderately complex issues involving model inference, data dependencies, deployment failures, service availability, latency, capacity, and infrastructure performance.
• Assess the operational impact and urgency of production issues and take appropriate action to restore services.
• Perform detailed root cause analyses for incidents, document findings, and recommend corrective and preventive actions.
• Identify recurring failure patterns and partner with engineering teams to implement permanent solutions.
• Support production readiness reviews and validate that new AI and machine learning services meet operational support requirements before release.
• Participate in an on-call rotation supporting a 24/7 production environment.

Incident and Problem Management

• Serve as a primary responder for AI- and MLE-related incidents identified through monitoring platforms, automated alerts, or user reports.
• Lead or coordinate the technical investigation of incidents within the role’s area of responsibility.
• Engage appropriate engineering, data, infrastructure, and vendor teams when cross-functional support is required.
• Maintain clear communication during incidents, including impact, status, mitigation actions, and expected next steps.
• Ensure incidents are tracked through resolution and that follow-up actions are documented and completed.
• Analyze operational metrics such as mean time to acknowledge, mean time to resolution, incident volume, availability, and recurring failure categories.
• Provide recommendations to improve reliability, supportability, and incident response effectiveness.

Deployment and Platform Support

• Support CI/CD workflows used to test, package, deploy, and promote machine learning models and AI services.
• Troubleshoot issues involving containers, Kubernetes workloads, cloud resources, infrastructure-as-code deployments, configuration, networking, permissions, and service dependencies.
• Assist with model and platform releases, including deployment validation, rollback support, and post-release monitoring.
• Partner with Machine Learning Engineers to improve deployment patterns, environment consistency, scalability, and recoverability.
• Help manage production configurations, operational dependencies, and service-level requirements across development, staging, and production environments.

Automation and Continuous Improvement

• Design and implement scripts, utilities, and automated workflows that reduce manual support effort and improve response times.
• Automate common operational activities such as service recovery, endpoint scaling, health validation, deployment checks, log collection, and resource-management tasks.
• Improve monitoring, logging, dashboards, alerts, and operational telemetry to provide earlier identification of production issues.
• Develop and maintain runbooks, troubleshooting guides, support procedures, and operational playbooks.
• Recommend improvements to architecture, tooling, processes, and support models based on operational experience.
• Contribute to reliability, resilience, capacity-planning, and disaster-recovery initiatives for AI and machine learning services.

Cross-Functional Collaboration

• Partner with Machine Learning Engineers to support the deployment, maintenance, and optimization of production models and machine learning infrastructure.
• Collaborate with Data Scientists and AI Engineers to ensure new solutions are supportable, observable, and production ready.
• Work with cloud, DevOps, cybersecurity, data engineering, and enterprise support teams to resolve issues spanning multiple technology domains.
• Provide technical guidance to junior support engineers and assist with knowledge transfer, troubleshooting practices, and operational procedures.
• Communicate complex technical issues clearly to both technical and nontechnical stakeholders.
