Sr Engineer Site Reliability
Job Summary
We are Optimum, a leader in connectivity, and we are seeking a Site Reliability Engineer III to optimize our Hybrid Cloud infrastructure. Your role will involve stabilizing and unifying our GCP and On-Premises environments into a single, reliable platform.
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): Deep proficiency in Linux (RHEL/Ubuntu) and Unix (Solaris/AIX) administration and kernel tuning, hands-on experience with GCP (IAM, VPC, Compute Engine), proven ability to manage complex environments using Terraform and Ansible, proficiency in Fiber Channel, iSCSI, and NFS, experience with enterprise arrays (NetApp, Dell/EMC, or Pure Storage), strong scripting ability in Python or Go to build internal tools and automation, strong understanding of CVE lifecycles and cryptographic standards (AES-256), familiarity with AI Tools and AI First mindset.
Education: 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.
