This role bridges software engineering and cloud operations, ensuring mission-critical systems remain highly available and resilient. By integrating reliability early, the SRE fosters a culture of shared responsibility while enabling rapid and safe feature delivery. What you will do • Design and build fault-tolerant, high-performing systems that meet Service Level Objectives (SLOs) and Service Level Agreements (SLAs). • Implement monitoring, alerting, distributed tracing, and logging to ensure real-time system health visibility and proactive issue resolution. • Act as a first responder for production incidents, conduct blameless postmortems, and drive root cause analysis (RCA) and corrective actions. • Develop self-healing, automated deployments, and scaling solutions to minimize toil and improve system efficiency. • Improve continuous integration and deployment pipelines to enable safe, rapid, and reliable feature rollouts. • Review code, debug issues, and perform quality assurance (QA) on software components to enhance system reliability and performance. • Work closely with development teams to ensure best practices in software architecture, coding standards, and operational readiness. • Forecast scalability needs and optimize cloud infrastructure costs while balancing performance and efficiency. • Ensure production environments meet security and compliance requirements, collaborating with teams to mitigate vulnerabilities and enforce best practices. • Work closely with development teams to embed reliability at every stage rather than treating it as an afterthought. • Use error budgets to balance feature velocity with system stability. • Implement observability and automation-first principles to measure system health and drive continuous improvement. • Leverage game days, chaos engineering, and resilience testing to validate system robustness and refine operational processes. What you will have • Extensive experience in distributed systems, cloud-native architectures (AWS, GCP, Azure), and DevOps practices. • Proficiency in Kubernetes, Terraform, CI/CD pipelines, and Infrastructure as Code (IaC). • Strong scripting and automation skills in Python, Go, Bash, or similar languages. • Expertise in observability tools such as Prometheus, Grafana, Datadog, Splunk, New Relic, and OpenTelemetry. • Ability to troubleshoot complex production issues and drive scalable, resilient solutions. • Experience reviewing code, debugging applications, and conducting software testing to ensure high reliability and quality.
