Cloud Infrastructure and Security Engineer

Position Summary

InfraSec builds and secures Harris Associates' cloud foundation on Microsoft Azure. The team runs the estate as code - identities, networks, virtual machines, Kubernetes, and data platforms are defined, reviewed, and deployed through automated pipelines rather than managed by hand. It's a lean, hands-on team that partners closely with DevOps, Data, and Application teams, and holds a high bar for security given the firm's regulated environment. The Cloud Infrastructure and Security Engineer is a hands-on, individual-contributor role at the center of this infrastructure-as-code operation, working across environments and cloud regions with deep involvement in identity, networking, compute, and data-platform security. We're looking for an experienced infrastructure or security engineer who thinks in systems, is comfortable owning production-grade cloud environments, and wants the scope to shape how a growing platform is built and secured.

Responsibilities

• AI-enabled tooling: Build and manage AI/LLM-based skills and agentic workflows that give the team leverage, governed under the same security review and least-privilege discipline as any other credentialed automation, with human review before anything ships.
• Patching and on-call: Share the team's operational rotations — patch the estate roughly three to four Saturdays a year, and serve as on-call first responder for infrastructure and security issues about one week a month, resolving directly or escalating as needed.
• Infrastructure as code: Author and maintain Terraform across roughly 18 repositories, multiple environments and regions, with Azure Storage state backends — holding the line on version/provider discipline, import safety, and plan-diff review.
• Identity and access management: Provision and govern Microsoft Entra ID — app-role and role-assignable groups, PIM/JIT, Conditional Access, Workload Identity Federation, and Microsoft Graph — designing least-privilege grants and auditing existing ones.
• Cloud networking: Design and operate hub-and-spoke topology, management-group policy and custom roles, NSG/firewall rules, routing, and trusted network locations, and troubleshoot when it breaks.
• Virtual machines and golden images: Provision hardened Azure VMs from a shared module (secure boot, vTPM, encryption at host, Hybrid Benefit), and build/maintain golden Windows Server images with Packer.
• Kubernetes and containers: Support the AKS platform alongside DevOps — workload identity, service-mesh and egress behavior, and connectivity troubleshooting.
• Data and analytics platform access: Govern access and security settings for Databricks, Snowflake, Power BI/Microsoft Fabric, and Purview, and manage platform-level governance.
• Monitoring and incident response: Keep signal high and noise low with Azure Monitor, and lead root-cause investigations across pipelines, capacity, and connectivity.
• CI/CD, review, and automation: Deliver every change through Azure Pipelines and a gated Terraform flow, review pull requests for what CI can't catch, and improve the automation itself.

Qualifications

• 7+ years of hands-on cloud infrastructure engineering experience, with production-grade experience on a major cloud platform (Azure preferred).
• Strong Infrastructure-as-Code skills - Terraform or a comparable tool - including state management, provider discipline, and safely importing existing resources.
• Solid grounding in identity and access fundamentals: RBAC, service principals/managed identities, and least-privilege design.
• Cloud networking expertise: hub-and-spoke or equivalent topologies, firewalls/NSGs, routing, and DNS.
• CI/CD delivery experience with a platform like Azure DevOps, plus scripting in PowerShell and/or Bash.
• A security-first mindset, with comfort working inside change-control and approval gates.
• Clear written communication skills for documenting decisions and processes.

Preferred

• Kubernetes/AKS operations experience - node pools, workload identity, and service mesh.
• Experience with Packer or golden-image build pipelines.
• Data-platform governance experience (e.g., Databricks, Snowflake, Power BI/Microsoft Fabric).
• Experience in a regulated or financial-services environment.

Special Requirements

This role shares the team's operational rotations: a monthly Saturday patching cycle (roughly three to four Saturdays per year) and a weekly on-call rotation (about one week per month) as first responder for infrastructure and security issues. Occasional early-morning, evening, or weekend work may be required to support patch windows and critical incidents. Flexibility with working hours is key.

Pay & Benefits

• Expected range for this Chicago-based role: $190,000 - $210,000 USD
• Comprehensive benefits package including medical, prescription drug, dental and vision insurance, paid time off, profit sharing plan, 401k plan, tuition reimbursement, commuter and holistic wellness benefits along with volunteer programs.
