Sr Site Reliability Engineer

Role Summary

The Senior System Analyst is responsible for ensuring the reliability, performance, and security of platform infrastructure across development, test, and production environments. This role focuses on building scalable and resilient Windows/Linux-based systems, improving operational readiness for deployments, and reducing operational toil through automation, monitoring, and engineering best practices.

This role sits within Platform Services and partners closely with application teams, infrastructure teams, and Dev Ops resources to implement scalable, resilient systems while minimizing operational toil.

• Platform Operations & Environment Readiness
• Configure and manage Windows and Linux systems, virtualization platforms, and core infrastructure services.
• Prepare environments for application deployments and validate infrastructure readiness for planned changes and new rollouts.
• Design, implement, and maintain scalable, secure Windows/Linux server environments supporting enterprise application deployments (configuration, upgrades, troubleshooting).
• Reliability Engineering, Monitoring & Observability
• Monitor infrastructure health and performance; proactively detect issues and drive resolution with a root-cause mindset.
• Establish and improve dashboards, monitoring standards, and alerting plans for systems and applications to enable proactive detection and rapid troubleshooting.
• Use monitoring/logging platforms (e.g., Logic Monitor, App Dynamics, and Splunk) to support observability and incident response.
• Automation & Engineering Best Practices
• Develop and maintain automation scripts (Power Shell, Python, Bash) to reduce manual tasks and increase consistency across environments.
• Lead automation initiatives using tools such as Ansible or Terraform where applicable; partner with platform teams to advance infrastructure-as-code and CI/CD integration.
• AI-Enabled Operations (AIOps) & Copilot Enablement
• Evaluate and apply AI-driven features within observability/monitoring tooling to reduce alert noise, improve anomaly detection, and prioritize telemetry for faster triage.
• Help operationalize intelligent dashboards and analytics that answer specific health and reliability questions for the portfolio and enable other teams to use them effectively.
• Use Microsoft 365 Copilot to accelerate creation of runbooks, post-incident summaries, knowledge base articles, and stakeholder communications while maintaining accuracy and appropriate data handling.
• Where appropriate and approved, contribute to building or refining internal copilots/agents (e.g., via Copilot Studio) to streamline support workflows and self-service access to operational knowledge.
• Cross-Team Partnership & Delivery Support
• Act as a liaison across IT infrastructure, security, and development teams; enable solutions spanning multiple IT teams.
• Collaborate with business partners and application development teams to build, refine, test, secure, and debug system capabilities as needed.
• Incident Management & Continuous Improvement
• Respond to system anomalies such as performance and vulnerability alerts; coordinate remediation with relevant teams.
• Conduct root-cause analysis for system-related incidents and drive actions that improve resilience and reduce repeat issues.
• Observe delivery workflows and recommend process/tooling improvements to increase efficiency.
• Documentation & Knowledge Management
• Author and maintain system and process documentation (workflow charts, diagrams, system specifications).
• Contribute to knowledge base content to support repeatable resolution of common issues and reduce escalations.

• 5+ years of experience in analysis, configuration and development on relevant platforms.
• 3+ years hands-on development experience with desired programming languages and database tools.
• 2+ year in an operations role providing production support for large enterprise grade applications.
• Demonstrated experience supporting and improving Windows and Linux-based systems in enterprise environments (dev/test/prod), including operational readiness for deployments.
• Strong troubleshooting and incident response capabilities, including root-cause analysis.
• Hands-on scripting/automation experience with Power Shell, Python, and/or Bash to reduce manual operational work.
• Experience implementing or operating monitoring/observability solutions (dashboards, alerting, log analysis) using tools such as Splunk and Logic Monitor.
• Proven ability to partner across application, infrastructure, and Dev Ops teams to deliver stable, scalable platform solutions.

• Infrastructure-as-code and automation experience using Ansible and/or Terraform.
• Experience supporting hybrid infrastructure and/or cloud transitions (Azure or similar).
• Experience with additional enterprise monitoring platforms such as App Dynamics and/or Solar Winds (where applicable).
• Security-minded administration experience (e.g., SSL certificate lifecycle, endpoint…
