You will lead 24/7 on call rotations, drive incident resolution, and help shape the reliability culture that serves millions of users researching schools and colleges.

What You Will Do

• Own and architect cloud infrastructure across AWS and GCP, including EC2, EKS/Kubernetes, RDS, ElastiCache, S3, and networking components (VPCs, load balancers, DNS), driving improvements that increase reliability and reduce operational burden
• Lead the design and implementation of secrets management strategies using Hashicorp Vault and other tools, establishing organizational standards for secure configuration management
• Architect and evolve infrastructure-as-code practices using Terraform, driving adoption of patterns that improve consistency and reduce deployment risk

• Support database operations including migrations and performance tuning
• Own Kafka clusters and message queue systems, including architecture decisions, capacity planning, and troubleshooting complex processing issues
• Participate in 24/7 oncall rotations, responding to alerts, triaging incidents, and coordinating with development teams to resolve production issues
• Design and implement monitoring, alerting, and observability strategies using Prometheus, Grafana, Sumo Logic, and related tools, establishing organizational standards that catch issues before customers notice them
• Define and own Service Level Indicators (SLIs) and Service Level Objectives (SLOs) for critical services, balancing business needs with engineering resources
• Lead blameless post-mortems, write comprehensive incident analyses that teach others, and drive systemic improvements that prevent entire classes of incidents
• Champion access controls, IAM policies, and security configurations across cloud environments, ensuring infrastructure meets compliance and security requirements
• Identify and eliminate systemic sources of operational toil by designing automation, building self-service tooling, and improving developer workflows that scale the team's impact
• Lead AI-assisted automation initiatives to streamline SRE processes, implementing solutions that reduce toil and improve incident response
• Partner with product development teams as the reliability subject matter expert, providing architecture guidance, production readiness reviews, and proactive capacity planning
• Mentor and coach SRE team members, helping them develop technical skills and operational judgment through pairing, code review, and incident response shadowing
