Job Summary

As a Site Reliability Engineer III, you will be a primary driver in the long-term management and stabilization of our Hybrid Cloud infrastructure. We maintain a permanent dual-hosting strategy, operating both Google Cloud Platform (GCP) and mission‑critical On‑Premises Unix/Linux footprint. You will bridge the gap between physical hardware and modern cloud‑native operations, applying software engineering principles to ensure our systems are scalable, secure, and predictable across all platforms.

The Mission

Hybrid Reliability & Stabilization

Your mission is to unify our GCP and On‑Premises environments into a single, reliable platform. Your first 12 months will focus on Stabilization and Observability. You will lead the transition away from "toil" (manual, repetitive operations) toward high‑leverage automation, aggressively addressing on‑prem technical debt while implementing modern SRE practices across our global data centers and cloud projects.

Responsibilities

• Hybrid Platform Standardization: Audit, harden, and standardize Unix (Solaris/AIX) and Linux (RHEL/Ubuntu) environments across both GCP Compute Engine and physical bare‑metal servers.
• Infrastructure Stewardship (DC Support): Serve as the engineering lead for our Eastern U.S. data centers; ensure hardware health, power redundancy, and physical security standards are enforced through code and automated checks.
• Storage Engineering (Specialization): Architect and manage enterprise‑grade SAN/NAS environments alongside GCP Cloud Storage/Persistent Disk. Optimize for low latency and high IOPS while ensuring all data‑at‑rest complies with our Annual Encryption Strategy.
• Automation of Toil: Design and maintain robust automation pipelines (Ansible, Terraform, Python) to ensure configuration parity and eliminate drift between cloud and on‑premises environments.
• Vulnerability Management: Transition the fleet from a "vulnerable" state to a "reliable" one by establishing a sustainable, automated monthly patching cadence. Unified Observability: Implement and scale a "single pane of glass" monitoring stack (Prometheus, Grafana, Loki) to provide real‑time health metrics for the entire hybrid estate.
• Incident Response & Post‑Mortems: Participate in a sustainable on‑call rotation. Lead Blameless Post‑Mortems for incidents involving cross‑platform dependencies to ensure we "fix the system, not the person".

Qualifications

Technical Requirements (SRE3)

• OS Internals: Deep proficiency in Linux (RHEL/Ubuntu) and Unix (Solaris/AIX) administration and kernel tuning.
• Cloud Proficiency: Hands‑on experience with GCP (IAM, VPC, Compute Engine) or equivalent public cloud providers.
• Infrastructure as Code: Proven ability to manage complex environments using Terraform and Ansible.
• Storage Protocols: Proficiency in Fiber Channel, iSCSI, and NFS. Experience with enterprise arrays (NetApp, Dell/EMC, or Pure Storage) is highly preferred.
• Software Engineering: Strong scripting ability in Python or Go to build internal tools and automation. Security: Strong understanding of CVE lifecycles and cryptographic standards (AES‑256).

The Ideal Candidate

• Bachelor’s degree in Telecommunications, Computer Engineering, or related discipline.
• 6+ years of experience in IP networking and infrastructure support, with at least 4 years in reliability‑focused roles.
