Principal Site Reliability Engineer 

Description: 

We are seeking a Principal Site Reliability Engineer (SRE) to support a mission-critical, on-premises “IT department in a box” model. This role ensures the reliability, security, and performance of a highly complex, compliance-driven hybrid infrastructure. You will provide broad support — from architecture and automation to daily system operations and hardening — with a focus on Red Hat Enterprise Linux (RHEL), Windows integration, and VMware-based virtualization. 

As a senior technical leader, you will drive the execution of site reliability engineering across system design, observability, security posture, and automation frameworks. This role requires deep experience across infrastructure layers and a strong commitment to operational excellence, security compliance, and continuous improvement. 

Key Responsibilities 

Mission-Critical Reliability & Recovery 

• Lead response and remediation efforts for complex, high-impact infrastructure issues such as: 

• Large-scale file permission repairs 

• System and service recovery 

• Act as the escalation point for high-severity incidents, providing root cause analysis and durable fixes. 

 

Linux & Hybrid Infrastructure Expertise 

• Apply deep knowledge of Red Hat Enterprise Linux (RHEL) at scale, including SELinux configuration and enforcement. 

• Design and implement secure, high-availability systems that span VMware, Windows, and Linux environments. 

• Manage distributed file operations and migration using tools such as rsync, find, and advanced shell scripting. 

Automation and Configuration Management 

• Lead the development of infrastructure-as-code using Ansible and YAML for system provisioning, state enforcement, and compliance. 

• Leverage Red Hat Satellite or equivalent tooling to manage configuration drift, patching, and lifecycle policies. 

Security Posture & Compliance Alignment 

• Own the implementation and enforcement of security hardening measures, including file integrity, SELinux policy tuning, access controls, and secure configuration baselines. 

• Collaborate with security teams to maintain posture in line with compliance frameworks (e.g., CIS Benchmarks, NIST, STIGs).
