5+ Years in Systems Engineering, DevOps, or SRE roles
Reports to the Head of Infrastructure & Platform Engineering
The Senior Site Reliability Engineer (RHEL Specialist) is a critical technical leadership role responsible for ensuring that our production environments are resilient, performant, and highly automated. Unlike traditional systems administration, this role treats infrastructure as a software problem. You will be the primary custodian of our Red Hat Enterprise Linux (RHEL) ecosystem, applying advanced engineering practices to manage thousands of nodes across on-premise virtualization and public cloud platforms.
Your mission is to bridge the gap between software development and systems operations by designing self-healing systems and robust Ansible-based automation frameworks. You will be expected to proactively identify system inefficiencies, optimize kernel performance, and architect CI/CD pipelines that empower development teams while maintaining strict production stability.
To engineer a world-class RHEL environment where manual intervention is the exception, not the rule. Through advanced automation and deep observability, you will ensure our services achieve 99.99% availability while enabling rapid, low-risk software delivery.
The Senior Site Reliability Engineer (RHEL Specialist) is responsible for the availability, latency, performance, efficiency, change management, monitoring, emergency response, and capacity planning of our enterprise Linux services. This role demands a unique blend of systems engineering expertise and software development skills to build and run large-scale, distributed, fault-tolerant systems.
Ansible Framework Design: Architect, implement, and maintain enterprise-grade automation solutions using Ansible for our Red Hat Enterprise Linux (RHEL) fleet. This includes developing custom Ansible roles, modules, and playbooks to automate system provisioning, configuration management, and patching.
Standard Operating Environment (SOE): Maintain and evolve the RHEL SOE across hybrid-cloud environments, ensuring consistency between on-premise virtualization (VMware/KVM) and public cloud instances.
Infrastructure as Code (IaC): Transform manual infrastructure workflows into automated code-based processes, ensuring that every component of the RHEL environment is version-controlled and reproducible.
Scripting & Tooling: Develop advanced scripts in Python and Bash to automate repetitive operational tasks (toil). You will be expected to build internal tools that enhance the productivity of the entire engineering organization.
System Integration: Write code to integrate infrastructure components with internal APIs, monitoring tools, and service management platforms to create seamless, end-to-end automated workflows.
A primary accountability of this role is the continuous identification of system inefficiencies. You will not just react to failures; you will actively hunt for potential failure modes, performance regressions, and architectural weaknesses, proposing and implementing automated fixes before they impact the business.
Defining SLOs/SLIs: Collaborate with product and development teams to define meaningful Service Level Indicators (SLIs) and Service Level Objectives (SLOs) that accurately represent the user experience.
Monitoring & Alerting: Design and implement comprehensive monitoring frameworks that provide deep visibility into RHEL system health and application performance, ensuring alerts are actionable and signal-rich.
Incident Management: Participate in a tiered on-call rotation and lead the response for critical production incidents. You will be responsible for stabilizing systems under pressure while maintaining clear communication with stakeholders.
The Senior Site Reliability Engineer (RHEL Specialist) must possess a deep technical foundation in enterprise Linux systems and modern DevOps methodologies. We are seeking a candidate who has transitioned from traditional systems administration to an automation-first engineering mindset, capable of managing complex, distributed environments.
A minimum of 5 years of professional experience in Site Reliability Engineering, DevOps, or Senior Linux Systems Administration is required. Candidates must demonstrate high-level proficiency in managing production RHEL environments at scale.
Ansible Expertise: Expert-level proficiency with Ansible Core and Ansible Automation Platform (Tower) . This includes architecting complex roles, utilizing Jinja2 templating, managing dynamic inventories, and developing custom Ansible modules to meet specific infrastructure needs.
Preferred Certifications: Red Hat Certified Engineer ( RHCE ), Red Hat Certified Architect (RHCA), or Certified Kubernetes Administrator (CKA) are highly desirable and will be given preference.
While technical proficiency in RHEL and automation is paramount, the effectiveness of a Site Reliability Engineer is heavily dependent on their ability to navigate complex organizational dynamics and maintain a calm, analytical mindset during system failures. We are seeking a candidate who embodies the cultural tenets of SRE: a blend of high empathy, radical transparency, and a relentless drive for efficiency.
The ideal candidate does not wait for an alert to trigger before acting. You should possess the ability to look at complex systems holistically and identify latent defects or architectural weaknesses. We value engineers who think strategically about "toil" and can justify automation efforts based on long-term reliability gains rather than short-term fixes.
Accountability: When systems fail, you focus on remediation and long-term prevention. You are comfortable standing by your technical decisions while remaining open to constructive feedback during blameless post-mortems.
We are looking for an individual who remains "calm under fire." The ability to maintain focus and lead a technical team through a high-pressure P1 incident is just as important as the code you write.
The Senior Site Reliability Engineer (RHEL Specialist) occupies a pivotal position within the technology organization, serving as a bridge between core infrastructure management and modern software delivery. This role is designed for a technical leader who can influence architectural decisions while remaining deeply embedded in daily operational excellence.
This position reports directly to the Head of Site Reliability Engineering (or the Director of Cloud & Platform Infrastructure ). This reporting line is structured to provide the SRE team with the necessary mandate to prioritize reliability, automation, and performance tuning over feature velocity when system stability is at risk.
While reporting into the centralized SRE leadership, the candidate will function within a cross-functional "Squad" or "Chapter" environment. This model emphasizes high-touch collaboration across various technical disciplines:
Software Development Teams: Collaborating as a "Reliability Consultant" to help developers architect RHEL-friendly applications, optimize container workloads, and refine deployment strategies.
Quality Assurance (QA): Working together to integrate automated reliability testing and performance benchmarking into the CI/CD pipeline.
Cybersecurity: Partnering with the SecOps team to automate RHEL hardening, manage SELinux policies, and ensure rapid, automated vulnerability patching.
Cloud Architects: Assisting in the design of hybrid-cloud solutions that ensure RHEL workloads move seamlessly between on-premise virtualization and public cloud platforms.
Our organization operates on a "You Build It, You Run It" (with SRE support) philosophy. As a Senior SRE, you are not a siloed gatekeeper; you are an enabler who empowers other teams through the creation of self-service automation and reliable platform abstractions.
