Principal Cloud Engineer - AI Agentic

Comcast · West Chester, PA · 2 mo ago
On-siteEngineeringFull-time

About the Role

Join the AI Agentic Team at Comcast, a Fortune 30 global media and technology company. This team is responsible for designing, building, and operating intelligent agents end-to-end, including agent logic, workflows, integrations, and decision frameworks. The Principal Cloud Engineer will focus on cloud infrastructure, platform reliability, automation, observability, and secure operations for AI-enabled and agentic systems in production. The role requires collaboration with engineering, AI platform, security, and operations teams, leveraging AI-augmented tools to enhance efficiency while ensuring reliability, security, and ethical use of AI technologies.

In most cases, Comcast prefers to have employees on-site collaborating unless the team has been designated as virtual. If a position is listed with both office locations and virtual offerings, Comcast may consider candidates who live greater than 100 miles from the office for the remote option.

Responsibilities

  • Design, implement, and operate cloud infrastructure supporting scalable, highly available AI-enabled and agentic platforms.
  • Apply Infrastructure as Code (IaC) practices (e.g., Terraform, Packer, Ansible) to provision and manage cloud resources consistently and securely.
  • Monitor platform health using metrics, logs, dashboards, and alerts, applying critical thinking to distinguish infrastructure, application, and AI-driven failures.
  • Lead troubleshooting and resolution of complex cloud and platform issues, including distributed system and integration failures.
  • Develop and maintain automation and tooling (primarily Python and shell scripting) to improve reliability, diagnostics, and operational efficiency.
  • Implement and evolve observability solutions (e.g., Prometheus, Splunk, Grafana, CloudWatch) to improve system transparency and alert quality.
  • Collaborate with application, data, and AI teams to ensure platforms are operable, observable, and scalable prior to and after release.
  • Support CI/CD pipelines and release workflows, enabling safe and repeatable deployments across environments.
  • Ensure secure cloud operations, including secrets management, access controls, encryption, and secure networking practices.
  • Apply foundational AI literacy to understand agent lifecycles, orchestration patterns, and non-deterministic execution behaviors that impact operations.
  • Use AI-assisted tools to enhance investigation, documentation, and optimization, while validating outputs with sound engineering judgment.
  • Contribute to and maintain runbooks, platform documentation, and operational standards.
  • Participate in on-call rotations and act as an escalation point during production incidents.
  • Perform other duties and responsibilities as assigned.

Requirements

  • Bachelor's Degree (or equivalent combination of coursework and experience, or extensive related professional experience).
  • 10+ years of relevant work experience.

Skills

Required

  • Cloud Infrastructure Engineering (AWS, Azure, or GCP).
  • Kubernetes & Container Platforms.
  • Infrastructure as Code (Terraform, Packer, Ansible, or equivalent).
  • Python Programming for automation and operational tooling.
  • Monitoring, Logging, and Alerting Systems.
  • CI/CD Tools and Release Automation.
  • Security Fundamentals (IAM, secrets management, encryption, network security).

Preferred

  • Experience supporting AI, ML, or agentic platforms in production.
  • Familiarity with data and streaming platforms (e.g., S3, SQS, Kafka-like systems).
  • Experience with PySpark, Databricks, or data processing pipelines.
  • Understanding of networking and protocol standards.
  • Exposure to hardware security modules (HSMs) or advanced key management solutions.
  • Experience operating large-scale distributed systems.
  • Cloud cost optimization and performance tuning experience.
