PRIMARY RESPONSIBILITIES

Define, implement, and own SLIs, SLOs, and error budgets for critical microservices in collaboration with product and engineering teams.

Use error budgets to influence release decisions, prioritize reliability initiatives, and manage operational risk.

Design and maintain observability platforms, including metrics, logs, traces, and real-time telemetry.

Track, manage, and reduce operational toil by converting repetitive operational tasks into Jira stories and epics with clear ownership and measurable outcomes.

Design, implement, and validate resiliency mechanisms such as graceful degradation, redundancy, automated failover, and disaster recovery.

Lead incident response efforts, act as an escalation point for high-severity incidents, and drive blameless postmortems.

Capture incident action items and reliability improvements in Jira, ensuring accountability, closure, and continuous improvement.

Partner with Scrum teams to improve reliability through release readiness reviews, production change validation, and testing strategies.

Perform deep root cause analysis, debugging, and performance tuning across distributed systems.

Promote shift-left reliability practices by embedding operability, monitoring, and failure testing early in the SDLC.

Drive continuous improvement through automation, self-healing systems, chaos engineering, and capacity planning.

Maintain runbooks, playbooks, and knowledge repositories, linking documentation to Jira tasks to reduce MTTR.

Provide technical leadership and mentoring to junior SREs and engineers.

Collaborate with global, distributed teams, leveraging Jira for transparent planning, dependency tracking, and execution.

Conduct production readiness reviews and ensure services meet operational excellence standards before deployment.

Track and improve operational KPIs such as availability, MTTR, MTTD, deployment success rate, and incident recurrence.

Collaborate with security and platform teams to ensure reliability, compliance, and operational security best practices are embedded into systems and deployment pipelines.

Explore opportunities to leverage AI-driven observability, anomaly detection, and operational automation to improve system reliability and reduce manual effort.

Experience with containerization and orchestration technologies such as Docker and Kubernetes (EKS, AKS, or GKE).

Familiarity with Infrastructure as Code (IaC) tools such as Terraform, CloudFormation, or Ansible.

Understanding of operational KPIs including availability, MTTR, MTTD, deployment success rate, and incident recurrence metrics.

Experience conducting production readiness reviews and implementing operational governance processes.

Ability to collaborate with security and platform engineering teams to ensure reliability, compliance, and operational security best practices.

Exposure to AI-assisted operations, anomaly detection, intelligent alerting, and automated remediation solutions.
