Job Description

Infrastructure Architect 
Location: Northfield/IL, Northbrook/IL (Hybrid)
Contract-To-Hire

About the Role

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

o Define the target state infrastructure architecture to support microservices, modern web frontends, and legacy system coexistence during migration.

o Lead design and implementation of infrastructure components on Microsoft Azure, including networking, storage, compute, security, and observability.

o Develop infrastructure blueprints and patterns to support Spring Boot APIs and Next.js MFEs.

o Collaborate with application and platform teams to guide the phased sunset of Oracle ATG systems.

· Cloud Infrastructure & DevOps

o Architect and implement Infrastructure as Code (IaC) practices using tools like Terraform, Bicep, or ARM templates.

o Define CI/CD infrastructure strategies using GitHub Actions, Azure DevOps, or similar tools.

o Champion containerization and orchestration using Docker, Kubernetes (AKS), and Helm.

o Implement Zero Trust security principles, role-based access, and ensure infrastructure compliance with enterprise standards.

o Work closely with security teams to ensure network segmentation, encryption, and threat detection are built into the infrastructure layer.

o Ensure high availability, disaster recovery, and auto-scaling designs are embedded across services.

o Conduct architecture reviews to optimize cost, performance, and reliability across cloud-native components.

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.
