Required Skills and Qualifications 6+ years of experience in Senior DevOps, Systems Engineering, or similar roles , ideally in high-availability production environments. Extensive, hands-on Kubernetes experience in production, including custom controllers / operators, CSI drivers , and multi-cluster management. Deep understanding of Co-location and bare-metal environments , including rack / stack, PXE booting, provisioning, and physical hardware management. Strong networking experience , including Cisco enterprise networking (routing, switching, VLANs, firewalls), and automating network configurations via Ansible or other tools. Expert-level coding skills in one or more of : Go, Python, Bash, TypeScript, Rust, including building automation tools, operators, and CLIs. Deep knowledge of VMware (vSphere, vCenter, ESXi, vSAN) , including scripting and automation using PowerCLI or similar tools. Expert-level Linux administration (RedHat, Debian / Ubuntu) and solid working knowledge of Windows Server, including Active Directory integrations and DNS. Strong experience with Infrastructure as Code (Terraform, Ansible) and configuration management principles. Advanced CI / CD knowledge , including pipeline design, artifact management, security scanning, and deployment strategies (GitOps, ArgoCD, FluxCD). Experience with observability stacks (NetData, New Relic, Prometheus, Grafana, Loki, ELK). Strong knowledge of ITIL processes , with experience working within structured incident, problem, and change management environments. Proven experience applying DevOps principles (CI / CD, IaC, GitOps, immutable infrastructure), and ability to communicate their value clearly to peers and management. Ability to lead, mentor, and collaborate with cross-functional teams , including development, operations, and security teams. Critical thinker who can innovate and find creative solutions to complex problems without relying on cloud-native offerings.
