Senior Technical Recruiter at Talent Groups

Location: Hybrid - McKinney, TX 75070

Type: Full-Time, Direct Hire. Applicants must be authorized to work in the United States without the need for current or future visa sponsorship. At this time, we are unable to consider candidates who require sponsorship.

We’re looking for a Senior Site Reliability Engineer (SRE) to architect, build, and own a Kubernetes-based infrastructure platform powering a high-performance, real-time, multi-tenant SaaS environment. This role is centered around on-premises Kubernetes in data center environments, with a strong focus on traffic enforcement, observability, and reliability at scale.

You’ll join a forward-thinking engineering team responsible for developing control systems, building traffic-routing logic, and maintaining a resilient cloud-native platform from the metal up. You’ll be hands-on in Kubernetes internals, networking, and automation—playing a critical role in ensuring reliability, performance, and visibility across the platform.

What You'll Do

• Own the architecture, operations, and lifecycle of on-prem Kubernetes clusters in high-scale production environments.
• Build and maintain observability stacks using tools like Prometheus, Grafana, OpenTelemetry, Jaeger, and Loki to provide actionable insight and proactive alerting.
• Implement and optimize Kubernetes-native traffic enforcement across multi-tenant SaaS workloads, including per-tenant fairness and routing enforcement.
• Work directly in Go to extend Kubernetes functionality via CRDs, operators, or controllers.
• Manage the care, feeding, and scaling of OpenStack clusters across global data centers.
• Lead SRE best practices: from automated remediation and capacity planning to disaster recovery and performance optimization.
• Design and manage advanced CNI configurations (Cilium, overlay networks, etc.) and modern SDN/NFV patterns.
• Collaborate with software engineering teams to ensure seamless integration between infrastructure and application layers.

Must-Have Qualifications

• Production-grade Kubernetes expertise—you’ve architected, deployed, and managed your own clusters on-prem (not just EKS/GKE/AKS).
• Hands-on experience with Kubernetes internals, including CRDs, controllers, and cluster APIs.
• Fluency in Go, with experience developing Kubernetes operators or integrations.
• Strong Linux engineering background, with deep command-line and troubleshooting expertise.
• Proven success building observability stacks (Prometheus, Grafana, OpenTelemetry, etc.).
• Experience with CNI plugins (e.g., Cilium, Calico, overlay networks) and container networking.
• Working knowledge of Python and Bash for scripting and automation.
• Experience with OpenStack (Nova, Neutron, Ceph) and its integration with Kubernetes environments.
• Familiarity with Helm, Terraform, ArgoCD, or Flux for Kubernetes GitOps and infrastructure automation.
• Exposure to service mesh tools like Istio or Linkerd.
