Title: Senior Engineer: Redis and Valkey on OpenShift
Location: Hybrid (New York, NY, Windsor, CT, Atlanta, GA, Minneapolis, MN, Scottsdale, AZ, Jacksonville, FL, Braintree, MA)

1. Experience & Qualifications

Professional Experience

• 10+ years of professional experience in infrastructure, DevOps, or platform engineering roles, with at least:
  • 5+ years of hands-on experience with OpenShift or Kubernetes.
  • 5+ years of experience with Redis (including production deployments, performance tuning, and advanced setups like clustering and Sentinel).
  • Proven expertise in deploying and managing stateful applications in cloud-native environments.
  • 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:
  • Millions of queries per second.
  • Large datasets requiring optimized memory usage.
  • Reliability demands of >99.99% uptime.

2. Core Technical Skills

A. Redis & Valkey (Highly Advanced Proficiency)

• Expert-level knowledge of Redis:
  • Master-slave replication.
  • Redis Sentinel for high availability.
  • Redis Cluster for horizontal sharding and distributed data management.
  • Memory optimization techniques for efficient handling of large datasets.
  • 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:
  • Helm charts to deploy and manage Redis/Valkey.
  • Developing and managing Operators with automation built in Ansible, Kustomize, or Terraform.
  • 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:
  • Prometheus (e.g., Redis exporter for Redis metrics).
  • Grafana dashboards for cluster state, replication lag, memory usage, and query performance.
  • 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:
  • TLS certificates for encryption in transit.
  • IP-based firewalls or OpenShift Network Policy for endpoint restrictions.
  • 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:
  • Mentor developers, DevOps engineers, and platform teams on Kubernetes/OpenShift setups and database best practices.
  • Own technical decisions around critical Redis/Valkey architecture, ensuring scalability and uptime.
• Collaboration and Communication:
  • Strong ability to coordinate with product teams, infrastructure architects, and security teams.
  • Prepare detailed technical design documents and present system architectures.
• Ownership and Problem Solving:
  • Take end-to-end accountability for Redis/Valkey in production environments.
  • 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.
