Senior Site Reliability Engineer

Position Specifications Attribute Details Position Title Senior Site Reliability Engineer (RHEL Specialist) Primary Location Remote Minimum Experience 5+ Years in Systems Engineering, DevOps, or SRE roles Reporting Structure Reports to the Head of Infrastructure & Platform Engineering Language Requirements Portuguese and English 1.3 Role Summary 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. Core Mission Statement: 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. 1.4 Ideal Candidate Profile The ideal candidate is a proactive problem-solver with a "software-first" approach to infrastructure. We are looking for an individual who: Possesses a deep-seated expertise in the RHEL kernel, system internals, and performance tuning. Views Ansible and Python as their primary tools for managing complexity at scale. Demonstrates a proven track record of managing Docker and Kubernetes workloads in high-traffic production settings. Is naturally curious and proactive, often identifying and resolving system bottlenecks before they trigger an alert. Thrives in a collaborative DevOps culture and is comfortable navigating the complexities of hybrid-cloud environments (AWS, Azure, or GCP). 2. Key Responsibilities 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. 2.1 Automation & Infrastructure Orchestration 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. 2.2 Development & Toil Reduction 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. Kernel & OS Optimization: Leverage deep Linux knowledge to tune system parameters and develop automated checks for system health and performance bottlenecks. 2.3 CI/CD & Release Engineering Pipeline Construction: Build and optimize robust CI/CD pipelines using Jenkins or GitLab CI to automate the testing and deployment of infrastructure code and application workloads. Deployment Strategies: Implement modern deployment methodologies such as Blue-Green or Canary releases to minimize downtime and risk during system updates. Artifact Management: Oversee the lifecycle of container images and software packages, ensuring they are securely built, scanned, and distributed across the RHEL landscape. Focus on Proactive Optimization: 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. 2.4 Service Level Management & Observability 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. Capacity Planning: Utilize performance data to forecast future resource requirements and automate scaling actions across the hybrid-cloud estate. 2.5 Incident Response & Reliability Leadership 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. Post-Mortem Analysis: Conduct blameless post-mortems to identify the root causes of incidents and drive the implementation of automated p… Read the full description on Himalayas.
