Senior Platform Engineer

The Senior Platform Engineer is a hands-on engineering role on a platform development team responsible for building and operating Flexential's IT platforms including observability, devops, ITSM incident and release mgmt, and Integrations technologies.

This role develops and manages critical platform subsystems for high availability, operational resiliency, security and scalability utilizing native-AI enablement for all outcomes. This is an individual contributor role with significant technical ownership and direct impact on critical Flexential technology roadmap.

You will work across infrastructure, automation, and application layers — deploying Kubernetes workloads, authoring Terraform modules, building Ansible playbooks, and building GitLab pipelines that other engineers depend on daily.

Key Responsibilities and 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 OpenTelemetry Central Backend Stack: Grafana Enterprise, Mimir, Loki, Tempo, and Alertmanager on Kubernetes/RKE2 via Helm and GitLab 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 OpenTelemetry Prometheus scrape profile library including SNMP exporters, REST API exporters, and cloud provider exporters (CloudWatch, 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 Alertmanager, 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 GitOps templates.
• Integrate Alertmanager with ServiceNow: webhook routing, ticket enrichment, auto-close logic, and escalation policy configuration.
• Maintain platform security: Conjur/CyberArk secret injection at runtime, mTLS between stack components, RBAC in Grafana Enterprise.
• Author and maintain Grafana dashboards in JSON/GitLab — 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.
• Perform other duties as required and assigned.
