• Drive adoption of operational best practices across observability, schema design, capacity planning, and cost optimization across storage systems
• Promote clarity and continuity by contributing to solutioning playbooks, decision logs, and architectural documentation

Skills

• Experience with distributed system concepts such as replication, partitioning, tunable consistency, and failure recovery
• Strong command of distributed system concepts such as replication, partitioning, tunable consistency, and failure recovery
• Experience with caching technologies like Redis or Memcached and know how to layer them effectively over storage systems to optimize for performance and cost
• Customer-first mindset, and thrive when working closely with product and platform teams to translate complex requirements into clean, scalable data models
