1. Redis
2. Valkey
3. OpenShift
Job Description/ Responsibilities
Professional Experience
10+ years of professional experience in infrastructure, DevOps, or platform engineering roles, with at least:
o 5+ years of hands-on experience with OpenShift or Kubernetes.
o 5+ years of experience with Redis (including production deployments, performance tuning, and advanced setups like clustering and Sentinel).
o Proven expertise in deploying and managing stateful applications in cloud-native environments.
o Track record of managing high-throughput, low-latency databases in real-time distributed systems.
Production Scale Experience
Experience operating Redis or similar in-memory databases (e.g., Memcached, Hazelcast) and key-value stores at enterprise scale with:
o Millions of queries per second.
o Large datasets requiring optimized memory usage.
o Reliability demands of >99.99% uptime.
Core Technical Skills
A. Redis & Valkey (Highly Advanced Proficiency)
Expert-level knowledge of Redis:
o Master-slave replication.
o Redis Sentinel for high availability.
o Redis Cluster for horizontal sharding and distributed data management.
o Memory optimization techniques for efficient handling of large datasets.
o Ability to debug, scale, and fine-tune Redis (e.g., handling eviction policies, tuning buffer utilization, and optimizing AOF/RDB persistence mechanisms).
Advanced knowledge of Valkey (or similar key-value database architectures), with a focus on scalability across distributed systems.
B. Automation (Infrastructure-as-Code):
Infrastructure-as-code expertise with:
o Helm charts to deploy and manage Redis/Valkey.
o Developing and managing Operators with automation built in Ansible, Kustomize, or Terraform.
o OpenShift-native CI/CD pipelines (Tekton/Red Hat Pipelines) for automated deployments and scaling.
C. Monitoring & Observability:
End-to-end monitoring of Redis and Valkey deployments with:
o Prometheus (e.g., redis_exporter for Redis metrics).
o Grafana dashboards for cluster state, replication lag, memory usage, and query performance.
o Centralized logging with the ELK stack (Elasticsearch, Logstash, Kibana) and OpenShift native logging solutions.
Expertise in interpreting metrics and logs for incident response.
D. Networking and Security:
Advanced knowledge of securing Redis/Valkey in cloud environments:
o TLS certificates for encryption in transit.
o IP-based firewalls or OpenShift NetworkPolicy for endpoint restrictions.
o External Secrets or OpenShift secrets for managing authentication credentials.
Expertise in debugging ingress, load balancing, and network latency issues.
3. Soft Skills
As a highly senior engineer, the individual is expected to bring advanced leadership and team collaboration skills:
Technical Leadership:
o Mentor developers, DevOps engineers, and platform teams on Kubernetes/OpenShift setups and database best practices.
o Own technical decisions around critical Redis/Valkey architecture, ensuring scalability and uptime.
Collaboration and Communication:
o Strong ability to coordinate with product teams, infrastructure architects, and security teams.
o Prepare detailed technical design documents and present system architectures.
Ownership and Problem Solving:
o Take end-to-end accountability for Redis/Valkey in production environments.
o Anticipate issues and proactively build systems to mitigate risks.
Challenges They Should Be Capable of Handling
1. Migrating Redis or Valkey deployments to OpenShift.
2. Zero-downtime upgrades for Redis clusters.
3. Guaranteeing max performance at peak loads (e.g., 1M+, high-throughput workloads).
4. Developing automated scaling and healing mechanisms for Redis on OpenShift.
