Role Overview

Position Summary

DevOps Platform Administrator supporting internal DevOps platform capabilities within a regulated healthcare environment. Primary focus on administering Azure DevOps agents (Linux/Windows), GitHub runners, JFrog Artifactory, SonarQube, and implementing GitOps with ArgoCD for Kubernetes deployments across Azure and AWS.

Key Responsibilities

• Design, implement, and maintain CI/CD pipelines (Azure DevOps, ArgoCD, GitOps)
• Support cloud platform infrastructure across Azure and AWS in hybrid/regulated environments
• Administer Azure DevOps agent pools (self-hosted Linux and Windows agents)
• Manage GitHub runners and GitHub organization administration
• Configure and maintain JFrog Artifactory for artifact management
• Integrate SonarQube for code quality gates in CI/CD pipelines
• Deploy, operate, and support containerized workloads on Kubernetes (AKS/EKS)
• Drive platform-wide initiatives including GitHub → Azure DevOps migrations
• Implement artifact management and build promotion workflows (JFrog Artifactory)
• Enhance observability across CI/CD pipelines, Kubernetes platforms, and tooling
• Develop automation scripts primarily in PowerShell
• Partner with application, platform, and infrastructure teams
• Participate in on-call rotations providing L3-level support
• Operate within healthcare compliance requirements (HIPAA, SOC2)

Required Technical Skills

• Cloud Platforms: Azure and AWS (hybrid enterprise environments)
• Containers & Orchestration: Kubernetes (AKS, EKS), Docker
• CI/CD & GitOps: Azure DevOps, GitHub, ArgoCD, GitOps workflows
• Artifact Management: JFrog Artifactory (preferred), Nexus, GitLab
• Scripting & Automation: PowerShell (required); Bash or Python
• Observability: CI/CD and platform monitoring, logging, operational tooling
• Source Control: Git-based workflows, build agent configuration

Interview Preparation Structure

Core Question Categories

1. "Tell Me About Yourself"
2. CI/CD & GitOps - Azure DevOps, GitHub, ArgoCD stories
3. Kubernetes & Platform Ownership - AKS/GKE, production incidents
4. Cloud Platforms - Azure/AWS hybrid environments
5. Migrations - GitHub → Azure DevOps, source control transitions
6. Artifact Management - JFrog/Nexus/GitLab workflows
7. PowerShell & Automation - Platform onboarding, operational scripts
8. Observability & On-call - Monitoring, L3 support, incident response
9. Compliance & Security - Regulated environments, HIPAA/SOC2
10. Behavioral - Team collaboration, conflict, decision-making

Humana Round 2 Focus Areas

For the Humana 2nd round, expect deeper questions in these areas:

• Azure DevOps agent pools – operational aspects, reliability, and cost optimization strategies.
• Automation with PowerShell, Ansible, and Terraform – agent maintenance and infrastructure as code.
• Troubleshooting CI/CD and platform reliability – pipeline stability, observability, and incident handling.
• Containers & Kubernetes (AKS and GKE) – real projects, production incidents, and lessons learned.

Map your answers to existing story files:

• Agent pools, CI/CD reliability → star-stories/ci-cd-gitops.md, star-stories/observability-oncall.md
• PowerShell/Ansible/Terraform → star-stories/powershell-automation.md
• AKS & GKE → star-stories/kubernetes-platform.md
• • Agent concepts & terminology → star-stories/agent-concepts.md
