Infrastructure Engineer

Overview

The Princeton DMIA Integration team is seeking an experienced Infrastructure Engineer to be the backbone of our Integration Services team. This role owns the provisioning, configuration, security, and ongoing maintenance of all infrastructure that supports our integration platforms - spanning API integrations, data pipelines, and the shared services that underpin them. You will work across our current on-premises Linux environment and be instrumental in building out the cloud infrastructure as we modernize our platform stack.

This position is a hybrid role.

Architect, Design and Develop

• Provision, configure, and maintain all infrastructure supporting integration, and data and platforms including WSO2, and related middleware on on-premises Linux servers.
• Design and build Azure cloud infrastructure hosting platform using AKS (Azure Kubernetes Service), and other Azure services for the organization’s next-generation API, data, and applications, following infrastructure-as-code (IaC) principles.
• Manage and harden on-premises server environments including OS patching, package management, service configuration, and security hardening on Linux.
• Administer IAM integrations including LDAP directory services, Active Directory, service account management, and certificate lifecycle management.
• Own network configuration relevant to integration workloads: DNS, firewall rules, load balancers, VPNs, and API gateway networking.

Collaborate and Coordinate

• Collaborate on CI/CD pipeline infrastructure, including build agents, artifact repositories, and deployment automation tooling.
• Support API and data engineering teams with environment provisioning, capacity planning, and performance tuning of integration runtimes.

Production Support

• Participate in on-call production support rotation and serve as escalation point for infrastructure-layer incidents.
• Implement and maintain monitoring, alerting, and logging infrastructure (log aggregation, metrics dashboards, uptime monitoring) for all integration services.
• Lead disaster recovery planning, backup procedures, and environment restoration for integration platform components.

• • Azure cloud infrastructure - compute, networking, storage, identity, security
