Role Title : Distributed Cache & DevOps Engineer
Must Have : Hazelcast , Redis / Redis Cluster, Apache Ignite
Role Summary
We are looking for a technically strong Distributed Cache Support Engineer to provide operational, technical, and production support for distributed caching solutions. The ideal candidate should have a strong Java background, prior experience with enterprise caching or in-memory data grid platforms, and hands-on exposure to DevOps and Kubernetes-based environments.
This role requires a hybrid profile combining Java backend engineering, distributed cache troubleshooting, platform operations, performance analysis, and production support.
Key Responsibilities
Cache Platform Support
- Provide L2/L3 support for Distributed Cache clusters and related application integrations
- Monitor cluster health, member status, partition distribution, memory utilization, latency, and throughput
- Support cache configuration, including distributed maps, Near Cache, eviction policies, TTL, backup count, serialization, and cluster discovery
- Troubleshoot cache-related incidents such as high latency, memory pressure, node restarts, split-brain scenarios, data inconsistency, and degraded performance
- Assist in capacity planning, performance tuning, and operational improvements for environments
- Coordinate with vendor support teams for product-level issues, patches, upgrades, and escalations
Java / Application Support
- Analyze Java application behavior related to distributed cache platform integration
- Troubleshoot JVM-level issues including heap usage, garbage collection, thread dumps, memory leaks, and serialization overhead
- Work with application teams to identify cache misuse, inefficient access patterns, and performance bottlenecks
- Support Spring Boot / Java microservices interacting with distributed cache platform
- Review and validate application-side configurations and integration patterns
DevOps / Kubernetes Operations
- Support distributed cache platform deployments running on Kubernetes or containerized environments
- Work with Kubernetes objects such as pods, services, namespaces, configmaps, secrets, deployments, and stateful workloads
- Analyze pod restarts, resource limits, liveness/readiness probe failures, service discovery issues, and container logs
- Support configuration management and deployment activities through CI/CD pipelines
- Assist with TLS/mTLS certificate-related troubleshooting where applicable
- Work with infrastructure and platform teams on network, DNS, storage, compute, and security-related issues
Monitoring, Incident & RCA Management
- Monitor platform and application metrics using tools such as AppDynamics, Splunk, Prometheus, Grafana, ELK, or similar
- Participate in incident management, troubleshooting calls, war-room support, and issue triage
- Prepare root cause analysis reports for production incidents
- Recommend preventive actions, operational improvements, and automation opportunities
- Maintain runbooks, SOPs, known-error documents, and support knowledge base articles
Required Skills & Experience
Mandatory Skills
- Strong hands-on experience in Java backend development or Java platform support
- Good understanding of JVM internals, memory management, garbage collection, thread dumps, and heap analysis
- Prior experience with distributed caching or in-memory data grid solutions
- Hands-on experience with at least one of the following:
Hazelcast
Redis / Redis Cluster
Apache Ignite
- Experience supporting applications in production or near-production environments
- Working knowledge of Kubernetes, containers, Linux, and basic networking
- Ability to analyze logs, metrics, alerts, and application behavior during incidents
- Strong troubleshooting, communication, and documentation skills
Preferred Skills
Direct hands-on experience with distributed cache platform & Understanding of:
- Distributed maps
- Near Cache
- Eviction and expiry policies
- Partitioning
- Backup/replication
- Split-brain protection
- Serialization
- Cluster discovery
- Experience with Spring Boot and microservices architecture
- Experience with CI/CD tools such as Jenkins, GitLab CI, Azure DevOps, or similar
- Exposure to Anthos, OpenShift, or enterprise Kubernetes platforms
- Experience with AppDynamics, Splunk, Prometheus, Grafana, ELK, or similar observability tools
- Knowledge of TLS/mTLS, certificates, service mesh, and secure service communication
- Experience working in banking, telecom, or other mission-critical enterprise environments.
Minimum Qualification
- Bachelor's degree in Computer Science, Software Engineering, Information Technology, or equivalent experience
- 5+ years of experience in Java backend development, platform engineering, or production support
- 2+ years of experience with caching, distributed systems, Kubernetes, or DevOps-related operations
- Prior production support experience in enterprise environments
