IT Infrastructure Support Site Reliability Engineer II

About the Job

We are seeking an experienced Site Reliability Engineer to join our IT Infrastructure Support team,
responsible for ensuring the reliability, scalability, and performance of critical physical security
infrastructure and supporting systems. In this role, you will combine software engineering expertise with
operations knowledge to build and maintain automation tools, monitoring systems, and processes that
support enterprise-grade server, network, and security device management. You will work closely with
cross-functional teams to define and enforce service level objectives, reduce operational toil through
automation, and drive continuous improvement in system resilience. This position requires 24x5
availability with on-call rotation to ensure uninterrupted support for mission-critical infrastructure.

Key Responsibilities

 Partner with leadership to establish, monitor, and enforce Service Level Indicators (SLIs) and
Service Level Objectives (SLOs) for infrastructure tooling, including configuration compliance
rates, patch success rates, and deployment latency metrics.
 Provide Level 3 expertise for tooling-specific incidents, focusing on automating incident
remediation workflows and reducing Mean Time To Repair (MTTR) through intelligent
automation and runbook development.
 Identify and automate repetitive manual tasks across managed infrastructure, targeting measurable
reductions in operational overhead (e.g., 50% reduction in manual server build time) through
scripting and workflow automation.
 Conduct thorough root cause analysis and lead blameless postmortems for all major service-
impacting incidents, driving systemic improvements in tooling reliability and infrastructure
resilience.
 Engineer and maintain automated processes and scripts to populate, update, and synchronize asset
management platforms (e.g., NetBox), configuration management databases, and monitoring
systems for internal and external stakeholders.
 Design, develop, and deploy full-stack applications, custom plugins, and automation scripts to
extend functionality of management and monitoring systems, enabling direct device interaction for
configuration management.
 Develop and maintain fully automated Infrastructure-as-Code configurations for Windows and
Linux server roles using tools such as Ansible, Terraform, or Puppet, including drift detection and
auto-remediation capabilities.
 Build end-to-end automation pipelines for vulnerability patching, security baseline enforcement
(CIS benchmarks), and continuous compliance auditing against internal and regulatory standards
for physical security devices.
 Develop API-driven tools for network configuration management, automated firmware updates,
pre/post-change validation, and real-time network health monitoring across the device fleet.
 Deploy and standardize monitoring agents, centralized log collection systems, and custom
dashboards with alerts based on critical SLIs (latency, error rate, saturation, traffic) for servers and
edge devices.
 Build automation scripts for intelligent ticket handling, problem validation, and escalation
workflows within enterprise ticketing systems, ensuring 2-hour initial response SLAs are
consistently met.
 Participate in 24x5 on-call rotation to provide timely support for infrastructure systems, security
devices, and related tooling, ensuring service continuity and rapid incident response.

Required Skills

 6+ years of experience in Site Reliability Engineering, DevOps, or Infrastructure Engineering
 Strong proficiency in Python, Bash, and PowerShell for automation scripting, with experience in
Go for building high-performance backend services and APIs.

 Hands-on experience with Infrastructure-as-Code tools (Terraform, Ansible, Chef, or Puppet) and
configuration management practices, including drift detection, version control, and automated
remediation.
 Advanced knowledge of Linux and Windows server environments, including Tier 3
troubleshooting capabilities, system hardening, and enterprise-scale server management.
 Solid understanding of enterprise networking concepts, Cisco device administration, network
automation protocols (NETCONF/RESTCONF), and experience with network monitoring and
flow analysis tools.
 Experience implementing and managing monitoring solutions (Prometheus, Grafana, Datadog)
and centralized logging platforms (ELK Stack), with ability to create custom dashboards and
alerting rules.
 Proficiency in implementing CI/CD pipelines, automated testing frameworks, and deployment
strategies using modern DevOps tooling, with strong emphasis on code quality, security, and
maintainability.
