• Experience operating production systems in a large cloud provider (e.g. AWS)
• Familiarity with containerized environments (Docker) and orchestration systems (Kubernetes)
• Experience with background job systems and message queues (e.g. Celery)
• Working knowledge of caching strategies (e.g. Redis)
• Experience with monitoring/observability tooling (e.g. Datadog, CloudWatch)
• Strong understanding of system reliability, failure modes, and operational tradeoffs
• Ability to communicate complex system behavior clearly to non-technical stakeholders
• A solutions-oriented mindset, willing to step outside your primary domain to unblock teammates and ensure successful delivery
