Working knowledge of networking (e.g., Redis over SSL, firewalls, clustering, and multi-region replication).
Configure and manage Redis Sentinel for automatic failover and monitoring.
Manage Redis sharding and clustering for distributed setups to support large-scale applications.
Monitoring & Performance Tuning:
High Availability and Scalability:
Security & Access Control:
Disaster Recovery and Backup:
Capacity Planning and Resource Management:
Collaboration with DevOps/Engineering Teams:
Documentation & Reporting:

Tools and Technologies:
Familiarity with Redis Sentinel for high availability and automatic failover.
Experience with Redis Cluster for horizontal scaling and sharding.
Familiarity with monitoring tools like Prometheus, Grafana, NewRelic, or other APM tools.
Exposure to containerization (Docker) and orchestration tools like Kubernetes for deploying Redis clusters in cloud and on-prem environments.
Proficient inscripting (Bash, Python, etc.) to automate Redis tasks like backups, restores, and monitoring.
Collaborate with DevOps, application developers, and infrastructure teams to ensure that Redis is integrated effectively into the overall system architecture.
Provide guidance on designing efficient data structures and choosing the appropriate Redis commands for application needs (e.g., strings, lists, sets, hashes, etc.).
Participate in code reviews to ensure Redis best practices are followed.

Preferred Skills:
Experience with cloud-based Redis deployments (AWS ElastiCache, Azure Redis Cache, Google Cloud Memorystore).
Experience in data security practices, including encryption, SSL, and access control management in Redis.
Knowledge of other NoSQL databases (e.g., Cassandra, MongoDB, Couchbase) to understand the broader NoSQL ecosystem.
