Description

As a Site Reliability Engineer your primary responsibilities include ensuring system reliability and availability. This involves monitoring performance, participating in on-call rotations, and helping to design highly available systems. You also automate and manage infrastructure, implementing Infrastructure as Code. Collaboration with cross-functional teams, documenting systems, and planning for capacity and scalability are crucial.

Responsibilities

• Monitor the health, performance, and availability of production systems, and respond to alerts to maintain agreed SLOs/SLAs
• Participate in on-call rotations, acting as a first responder to production incidents — triaging, diagnosing, and resolving issues across the full stack (infrastructure, backend services, and client-side/front-end).
• Design, build, and maintain highly available, fault-tolerant systems across on-premise and cloud environments (AWS/GCP), incorporating redundancy and failover best practices.
• Automate infrastructure provisioning and configuration using Infrastructure as Code and configuration management tools (e.g., Ansible, Puppet, Terraform)
• Develop and maintain operational tooling and automation scripts in Python or Go to streamline workflows, improve observability, and reduce repetitive manual work
• Administer and optimize Kubernetes clusters and container orchestration for scalability, resilience, and efficient resource utilization
• Conduct capacity planning and performance tuning — analyzing traffic patterns, resource utilization, and application behavior to proactively scale systems ahead of demand
• Perform root cause analysis on incidents and participate in postmortems, translating findings into concrete reliability improvements and preventive automation
• Document system architecture, runbooks, and operational procedures clearly for both technical and non-technical stakeholders
• Contribute to the ongoing evolution of reliability practices and infrastructure automation standards across multi-platform cloud and on-premise environments

Minimum Qualifications

• 3 years hands-on experience as a systems, storage or cloud engineer
• Knowledge of Linux (OEL, RHEL, CentOS) utilities and programs
• Expertise in version control systems (Git, SVN), automated build and testing (Jenkins, Vagrant)
• Expertise in Kubernetes platform, on-premise or Cloud
• Expertise with at least one cloud infrastructure platform (AWS, GCP)
• Understanding of enterprise storage platforms (NetApp, Isilon, Object Storage, etc.)
• Experience with configuration management (e.g. Puppet, Ansible)
• Understanding of virtualization technologies (VMware, KVM)
• Experience automating workflows with Python or Go
• Knowledge of networking technologies including IPv4/IPv6, DNS, network segmentation, etc.

Preferred Qualifications

• 5+ years of hands-on experience in an SRE role including technical ownership of production systems at scale
• Background supporting high-traffic, consumer-facing web platforms
• Excellent verbal and written communication skills — able to articulate, document and otherwise communicate technical concepts/details to both technical and non-technical audiences
• Working knowledge of basic web technologies including HTTP, HTML, CSS, JS etc. and hands on experience debugging web applications at the network/protocol level
• Experience with GitOps infrastructure automation
• Experience with multi-platform cloud and on-premise applications at scale, particularly with AWS and/or Alicloud
• Experience building web applications and services at scale in Go
• Experience performance-tuning web applications, especially across all contributing factors
