Core Responsibilities

Primary Functions

  • Design, build, and operate robust monitoring, logging, and alerting solutions to provide deep insight into system health and performance.
  • Lead and coordinate real-time incident response efforts, including triage, troubleshooting, and post-mortem analysis to identify root causes and prevent recurrence.
  • Develop and enforce Service Level Objectives (SLOs) and Service Level Indicators (SLIs) in close collaboration with product and engineering teams.
  • Automate infrastructure provisioning, configuration, and application deployments using Infrastructure as Code (IaC) tools like Terraform, Ansible, or Pulumi.
  • Systematically reduce operational toil by identifying repetitive manual tasks and building automated solutions, scripts, and tools to eliminate them.
  • Participate in a sustainable on-call rotation, serving as the first line of defense for production issues and ensuring timely resolution.
  • Proactively conduct capacity planning and performance analysis to ensure our systems can handle future growth and traffic spikes.
  • Build, maintain, and enhance CI/CD pipelines to enable fast, safe, and reliable software delivery for development teams.
  • Engage in and improve the entire lifecycle of services—from inception and design, through deployment, operation, and refinement.
  • Collaborate on architectural and design reviews for new services, providing critical feedback on reliability, scalability, and security.
  • Conduct blameless post-mortems and Root Cause Analyses (RCAs) to drive a culture of continuous improvement and learning from failures.
  • Manage and maintain our cloud infrastructure (AWS, GCP, Azure), optimizing for cost, performance, and security.
  • Implement and manage container orchestration platforms like Kubernetes, ensuring the reliability and scalability of containerized applications.
  • Develop disaster recovery plans and execute regular testing, such as chaos engineering experiments, to validate system resilience.
  • Troubleshoot complex distributed systems issues, spanning applications, networking, databases, and underlying infrastructure.
  • Create and maintain comprehensive documentation, including system architecture diagrams, runbooks, and operational procedures.
  • Act as a subject matter expert on reliability for the entire engineering organization, mentoring other engineers and promoting best practices.
  • Analyze system performance metrics and logs to identify bottlenecks, bugs, and opportunities for optimization.
  • Secure production infrastructure and services by implementing security best practices and responding to potential vulnerabilities.
  • Drive the adoption of reliability engineering principles and practices across multiple development teams.
  • Evaluate, deploy, and manage third-party tools and services that enhance our observability and operational capabilities.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis related to system performance and incidents.
  • Contribute to the organization's long-term technology strategy and infrastructure roadmap.
  • Collaborate with business units to translate data needs and reliability concerns into actionable engineering requirements.
  • Participate in sprint planning, backlog grooming, and agile ceremonies within the reliability engineering team.
