Site Reliability Engineer

• Provide expert guidance on managing large data centers, including hundreds of bare metal servers and virtual machines (VMs), ensuring optimal configuration and performance.
• Monitor and troubleshoot system performance, reliability, and availability using modern observability tools and techniques, with strong emphasis on diagnosing and resolving issues in operating systems and bare metal environments.
• Manage the server hardware lifecycle — firmware and BIOS baselines, out-of-band management, failure triage, vendor and RMA coordination, capacity forecasting, and refresh planning.
• Administer virtualization platforms and manage storage appliances across all data center locations worldwide.
• Automate bare metal  and VM provisioning and OS lifecycle at scale.  
• Work hands-on with data center network infrastructure — VLANs, routing, link aggregation, load balancers, and firewall rules — troubleshooting latency, throughput, and packet loss from the Linux host outward, including multi-site and colocation resiliency. 
• Design, implement, and maintain scalable, reliable infrastructure using containers, Kubernetes, and microservices architecture, including clusters on bare metal and on-premises VMs. 
• Oversee configuration management for consistent, reliable releases across environments, using Ansible for system configuration, patch management, and provisioning across data center infrastructure, and eliminating configuration drift across the fleet. 
• Design and operate high-throughput Kafka clusters for event streaming — topics, partitions, replication, consumer lag monitoring, and disaster recovery across data center infrastructure. 
• Implement name services and server management practices, including DNS, DHCP, NTP, directory and authentication services, and certificate management. 
• Collaborate with development teams to influence system design choices and operational policies, and continuously evaluate and integrate new technologies, hardware platforms, and automation approaches to improve operational efficiency and reliability. 
• Participate in on-call rotations supporting production systems, conduct blameless post-mortems with root cause analysis, and maintain incident response runbooks and procedures. 
• Create comprehensive technical documentation — runbooks, architectural diagrams, network topology maps, rack elevations, and capacity models — and maintain knowledge bases for operational procedures and best practices.
