Qualifications

• Formal training or certification in Infrastructure Engineering concepts and 6+ years applied experience operating distributed infrastructure in production environments; strong problem-solving across projects of moderate scope.
• Extensive experience on No-SQL products like MongoDB, with architecture, backup and recovery, exposure to performance troubleshooting; shard knowledge is a plus.
• Production experience with Redis (cluster mode, replication, persistence via RDB/AOF); capacity and performance management for low-latency use cases.
• Strong Linux and networking skills, including tuning OS/network parameters and understanding DNS and load balancing in enterprise environments.
• Experience designing dashboards/alerts in Splunk/Dynatrace or equivalent for JVM/GC, heap/off-heap, queue depth, client connections, and WAN metrics; partner across teams to identify capacity risks.
• Foundational understanding of containers and orchestration (Kubernetes) to operate cache services interacting with containerized clients and platform tooling.
• Experience tuning Linux parameters for performance.
• Exposure to microservices architectures and REST APIs used by cache clients; understanding authentication and data structures for secure, efficient cache access patterns.
• Experience automating and managing database tasks using Python and API framework.
• Experience in developing and using AI skills/agents.

Responsibilities

• Operate and support on and off-prem No-SQL products like MongoDB, Graph and Cache Db products across dev/QA/production, performing incident triage, root-cause analysis, and recovery for member failures, region issues, and client connectivity, with end-to-end monitoring and appropriate escalation paths.
• Manage capacity and performance on physical/VM infrastructure.
• Execute controlled rolling upgrades, patching, and configuration changes via on-prem change management; validate in lower environments, plan maintenance windows, and deliver zero/low-downtime outcomes using conventional approaches to break down technical problems and drive remediation.
• Monitor cluster health using on-prem observability stacks (e.g., Splunk, Dynatrace, Grafana): build dashboards and alerts.
• Maintain KBs/runbooks; coordinate with platform, network, storage, and vendor teams for hardware/network incidents, patch validation, and cross-platform architecture changes to modernize processes and resolve issues of moderate complexity.
• Apply Linux and networking fundamentals (TCP, DNS, load balancing) and container/orchestration basics (e.g., Kubernetes) where applicable; leverage automation and scripting to scale operations and improve resiliency.
• Add to a team culture of diversity, equity, inclusion, and respect; be accountable for significant decisions across projects spanning multiple technologies and applications.
