Senior Site Reliability Engineer (S3 Storage)

Quick Facts

• Role: Senior Site Reliability Engineer focused on S3 storage reliability
• Focus: 99.99%+ uptime, monitoring/automation, incident response, scalable and compliant object storage

Description

Design and implement monitoring, alerting, and automation for S3 storage clusters to achieve 99.99%+ uptime. Build forecasting and scaling plans for multi-region S3 deployments up to 150 PB+ using lifecycle policies, bucket management, and replication. Lead on-call rotations, troubleshoot incidents, and perform blameless post-mortems.

Responsibilities

• Design and implement monitoring, alerting, and automation for S3 storage clusters
