Essential Job Functions:

Design, develop and operationally manage automated, resilient, high availability, self-healing, secure platforms with native-AI capabilities for IT needs, serving both internal as well as customer business capabilities

Develop, and manage the Observability Open Telemetry Central Backend Stack:
Grafana Enterprise, Mimir, Loki, Tempo, and Alert manager on Kubernetes/RKE2 via Helm and Git Lab CI-CD.Build and manage iaC and CI-CD for automated provisiong and deployment, including Terraform modules for Infra/VM/storage provisioning, Ansible AWX playbooks for OS/App bootstrap, ArgoCD and Helm for Kubernetes configuration.

Develop and manage Open Telemetry Prometheus scrape profile library including SNMP exporters, REST API exporters, and cloud provider exporters (Cloud Watch, Azure Monitor, GCP) for multiple device classes.

Develop AIOps capabilities on platforms for e.g Observability use-cases: anomaly detection integrations, event correlation rules in Alert manager, and synthetic monitoring patterns to reduce alert noise.

Configure and maintain Zabbix auto-discovery: network range scanning, device classification, and Prometheus service discovery integration.

Build and harden Edge Stack deployments (Prometheus + OTel collector) per data center site using Git Ops templates.

Integrate Alert manager with Service Now: webhook routing, ticket enrichment, auto-close logic, and escalation policy configuration.

Maintain platform security:
Conjur/Cyber Ark secret injection at runtime, mTLS between stack components, RBAC in Grafana Enterprise.

Author and maintain Grafana dashboards in JSON/Git Lab — facility overview, network health, RED metrics, application telemetry.

Mentor mid-level engineers, lead code reviews, and establish engineering standards for the team. Represent platform engineering in cross-functional architecture reviews and executive-level program updates.
