Reports to the Head of Infrastructure & Platform Engineering

Portuguese and English

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.

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).

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.

Hands-on experience with Docker/Podman and enterprise orchestration via Kubernetes or Red Hat OpenShift.

Experience managing RHEL workloads on VMware vSphere and/or KVM (libvirt/QEMU) environments.

Practical experience managing Linux infrastructure in at least one major cloud provider: AWS, Azure, or GCP.

Proficiency in building and managing deployment pipelines using Jenkins or GitLab CI.

Mentorship, code review of Ansible playbooks, and guiding technical troubleshooting.

Negotiating SLOs and providing data-driven insights on how system reliability impacts user experience.

Managing technical support escalations and staying informed on upcoming RHEL roadmap features.
