The Senior Site Reliability Engineer will serve as the first line of defense for our 24/7 operations. You will act as the guardian of our production environment, utilizing Dynatrace to maintain a holistic view of both Infrastructure and Application health.

You will not just monitor uptime; you will actively test system resilience, manage major incidents, and facilitate stability reporting. You will be the primary notification point for all P1/P2 incidents, responsible for deep-dive triage, quick remediation, and coordinating Major Incident Management (MIM).

Primary Responsibilities:

24/7 Incident Command & Alerting

• 24/7 Availability: Participate in a shift rotation or on-call schedule to ensure continuous coverage. You are the "eyes on glass" for the organization.
• Unified Alerting: Manage the notification workflow. Ensure that Critical Alerts for both Infrastructure failures and Application failures trigger immediate notifications to the 24/7 team.
• Major Incident Management (MIM): Lead the technical response during critical outages. Coordinate cross-functional teams to restore service rapidly.
  
  

Observability Strategy (Dynatrace Focus)

• Dynatrace Administration: Act as the Subject Matter Expert (SME) for our Dynatrace implementation.
• Configure Management Zones, Alerting Profiles, and Dashboards to provide a "Single Pane of Glass."
• Utilize Dynatrace PurePath for distributed tracing to identify bottlenecks in microservices.
• Leverage Davis AI to automatically detect anomalies and reduce alert noise.
• Comprehensive Monitoring Scope:
• Network Health: Monitor VPN Tunnel status, Load Balancer (ALB/NLB) health, and DNS latency. Trigger: Alert on packet loss or high latency.
• Infrastructure Health: Monitor Disk/Volume usage, CPU/Memory saturation, and SSL Certificate expiry.
• Security: Monitor for DDoS attack patterns and WAF spikes.
  
  

Resilience & Chaos Engineering

• Chaos Engineering: Plan and execute Chaos Engineering exercises (e.g., simulating pod failures, network latency, zone outages) to test the systems resilience and verify that failover mechanisms work as expected.
• Reliability Recommendations: Proactively analyze trends and provide architectural recommendations to development and infrastructure teams to improve system stability.
• First Line Troubleshooting: Serve as the L1/L2 troubleshooter for Kubernetes (EKS), AWS, and Linux issues. Execute "Quick Fix" runbooks to mitigate impact before escalating to platform engineering.
  
  

Application Triage & Analysis

• Deep-Dive Triage: Go beyond "system check" to perform deep analysis using Dynatrace. Analyze stack traces and exception logs to pinpoint the exact line of code causing the failure.
• Root Cause Differentiation: Rapidly differentiate between an Infrastructure Issue (e.g., Network timeout) vs. an Application Logic Error (e.g., NullPointer caused by bad data).
• Blameless RCA: Facilitate Root Cause Analysis sessions to ensure permanent fixes are applied to recurring problems.
  
  

Governance & Reporting (Stability Cadence)

• Stability Calls: Facilitate and lead the Weekly/Bi-Weekly Stability Call. Present the health status of all technical towers to leadership and stakeholders.
• Reporting: Generate regular reports on system uptime, error budgets, incident trends, and MTTR (Mean Time To Recovery).
• Cross-Tower Visibility: Ensure that the dashboards and reports provide value to all teams (Network, App, Cloud), ensuring no siloed "blind spots" in production.
  
  

Automation & Toil Reduction

• Remediation Scripting: Develop scripts (Python/Bash) to "Auto-Heal" common issues (e.g., clearing logs when disk is full, restarting stuck services).
• Process Improvement: Identify manual checks and convert them into automated Dynatrace alerts or synthetic tests.
  
  

Qualifications:

• Shift Availability: Must be willing to work in a 24/7 shift environment or strictly defined on-call rotation.
• Dynatrace Expertise: Deep experience administering and using Dynatrace in a production environment (Dashboards, OneAgent, PurePaths).
• Troubleshooting Expertise:
• Network: Understanding of DNS, TCP/IP, Load Balancing, and Firewalls.
• Compute/Storage: Understanding of block vs. object storage, CPU stealing, and memory management.
• Governance: Experience facilitating technical management calls and producing executive-level reliability reports.
• Application Debugging: Ability to read application logs (Java, Node, Python) to understand why a service failed.
• Cloud (AWS) & K8s: Solid understanding of EKS, EC2, and other AWS Services
