Infrastructure Architect / Illinois

We are seeking an experienced Infrastructure Architect to lead the modernization and evolution of our enterprise platform. Our current technology stack includes a legacy Oracle ATG-based ecommerce system, which is transitioning to a modern cloud-native architecture featuring Azure, Spring Boot microservices, and a Next.js-based micro frontend (MFE) framework. This role will drive the infrastructure strategy, ensure secure and scalable design patterns, and support the build-out of our cloud-native application ecosystem.

Key Responsibilities

• Architecture & Strategy
  • Define the target state infrastructure architecture to support microservices, modern web frontends, and legacy system coexistence during migration.
  • Lead design and implementation of infrastructure components on Microsoft Azure, including networking, storage, compute, security, and observability.
  • Develop infrastructure blueprints and patterns to support Spring Boot APIs and Next.js MFEs.
  • Collaborate with application and platform teams to guide the phased sunset of Oracle ATG systems.
• Cloud Infrastructure & DevOps
  • Architect and implement Infrastructure as Code (IaC) practices using tools like Terraform, Bicep, or ARM templates.
  • Define CI/CD infrastructure strategies using GitHub Actions, Azure DevOps, or similar tools.
  • Champion containerization and orchestration using Docker, Kubernetes (AKS), and Helm.
• Security & Compliance
  • Implement Zero Trust security principles, role-based access, and ensure infrastructure compliance with enterprise standards.
  • Work closely with security teams to ensure network segmentation, encryption, and threat detection are built into the infrastructure layer.
• Performance, Resilience & Cost Optimization
  • Ensure high availability, disaster recovery, and auto-scaling designs are embedded across services.
  • Conduct architecture reviews to optimize cost, performance, and reliability across cloud-native components.
• Cross-functional Collaboration
  • Partner with application architects, frontend developers, DevOps, and security teams to deliver seamless integration between infrastructure and applications.
  • Provide technical leadership and mentoring to engineering and operations teams.

Required Qualifications

• 8+ years of experience in infrastructure or cloud architecture, with 3+ years in Azure.
• Deep experience with Azure services (App Services, AKS, VNet, Key Vault, Storage, Functions).
• Strong knowledge of Spring Boot based microservice infrastructure patterns.
• Familiarity with Next.js or other React-based micro frontend patterns.
• Hands-on experience modernizing Oracle ATG or other monolithic legacy systems.
• Proficiency with Infrastructure-as-Code (Terraform, ARM, Bicep).
• Understanding of container platforms (Docker, Kubernetes, AKS).
• Strong understanding of cloud security, performance tuning, and operational excellence.
