Responsibilities
- System Reliability: Monitor and maintain the health, availability, and performance of critical transportation services
- Reliability Standards: Define and track service-level objectives (SLOs), error budgets, and reliability metrics for revenue-critical services
- Incident Management: Lead incident response — perform root cause analysis, coordinate resolution across teams, and drive blameless post-incident reviews and follow-up actions
- Automation: Develop and implement automation scripts to streamline operational tasks and improve efficiency
- Monitoring & Performance: Set up and maintain monitoring, logging, tracing, and alerting tools (e.g., Prometheus, Grafana, OpenTelemetry) to track service health, performance, and resource utilization
- Capacity Planning: Help assess and plan for capacity, scaling infrastructure to meet growing transaction volumes — including stateful systems such as distributed SQL databases and event-streaming clusters (e.g., NATS, Kafka)
- Collaboration: Work with software engineering, infrastructure, and operations teams to improve the reliability of systems and services
- System Optimization: Identify performance bottlenecks, troubleshoot issues, and work on optimizations at both infrastructure and application layers
- Continuous Improvement: Contribute to the ongoing improvement of operational processes, documentation, and best practices in the SRE team
- Disaster Recovery: Participate in designing and testing disaster recovery plans to ensure the continuity of critical services
Skills
