DevOps / System Administrator (Project Based)

DevOps / System Administrator Redis (Project Based 6 Bulan)

About the Role This is a senior, highly technical role at the heart of our Redis infrastructure project. You will be responsible for the architecture, deployment, and operational health of our Redis Enterprise clusters — including live data migration across clusters. You will also be the primary authority on replication topology, CRDB configuration, and cluster-level performance. We expect you to bring both deep Redis Enterprise expertise and the operational discipline of a seasoned infrastructure engineer.

Job Description

• Architect and deploy multi-node Redis Enterprise clusters in server-based environments
• Lead the implementation and upgrade of multiple Redis clusters, including data migration planning and execution
• Design and validate migration strategies using tools provided by Redis
• Configure and manage Active-Passive and CRDB replication topologies across data centres
• Define and enforce cluster configuration standards — eviction policies, persistence, ACLs, etc.
• Lead post-migration data integrity validation and risk assessment
• Mentor the mid/junior Redis Administrator and review their work
• Collaborate with the Technical Lead on migration runbooks and rollback plans
• Serve as the escalation point for cluster-level incidents and performance issues

Requirements :

• 5+ years of experience in infrastructure or platform engineering, with at least 3 years working directly with Redis or Redis Enterprise
• Deep, hands-on knowledge of Redis Enterprise cluster architecture — node roles, shard distribution, replication, and failover
• Proven experience executing or planning Redis cluster migrations or version upgrades in production
• Strong understanding of Redis data structures, persistence mechanisms (RDB/AOF), and eviction policies
• Familiarity with Redis Enterprise REST API for cluster and database management
• Experience with Docker, Docker Compose, or Kubernetes for stateful workload deployment
• Solid scripting skills in Bash or Python for automation and tooling
• Experience with CRDB, Replica Of, or Active-Active replication is strongly preferred

Plus Points;

• You have hands-on experience with Redis Enterprise specifically, not just open-source Redis
• You have planned and executed a rip-and-replace or major version migration of a Redis cluster in a production environment
• You understand the data loss risk profile of different migration strategies and can articulate tradeoffs clearly
• You are comfortable reading and writing against the Redis Enterprise REST API to automate cluster operations
