Description and Requirements

We are seeking a skilled Golang Engineer to design and implement comprehensive monitoring and observability solutions for our cloud infrastructure. This role is responsible for building scalable monitoring systems that provide real‑time visibility into system health and performance across Linux, OpenStack, and Kubernetes environments.

Key Responsibilities

• Design and develop core components of Kubernetes‑based container platforms using Golang, focusing on control plane extensions, operators, and cloud‑native service meshes.
• Implement and optimize Kubernetes networking (CNI plugins like Calico/Cilium) and storage solutions (CSI drivers, Rook/Ceph integration), addressing challenges in multi‑tenant isolation and high‑throughput data paths.
• Troubleshoot deep‑level Kubernetes issues (e.g., etcd corruption, kube‑scheduler deadlocks, CNI policy conflicts) using Golang debugging tools (pprof, delve) and log analysis.
• Build automation frameworks for cluster lifecycle management, security hardening, and observability using Golang (primary) and Python (secondary for scripting).
• Collaborate with infrastructure teams to align platform capabilities with AI workload requirements, optimizing resource scheduling for GPU/accelerator workloads.

Qualifications

Technical Expertise:

• Mastery of Golang: 3+ years building production‑grade systems with goroutines, interfaces, and standard library (e.g., net/http, k8s.io/client‑go).
• Kubernetes Internals: Deep understanding of control plane components (API server, scheduler, controller manager) and ability to extend via CRDs/Operators.
• Network/Storage Proficiency: Hands‑on experience selecting and implementing CNI (VXLAN/BGP modes) and CSI solutions (RBD, iSCSI), with performance benchmarking skills.
• Linux/Container Expertise: Proficient in cgroups, namespaces, and container runtimes (containerd, CRI‑O) for debugging resource leaks or security flaws.

Experience:

• 3+ years developing cloud infrastructure with Golang as primary language, including at least one major Kubernetes platform project (e.g., cluster autoscaler, custom scheduler).
• Demonstrated ability to resolve critical production issues (e.g., etcd leader election failures, network policy drops) in large‑scale clusters (>1k nodes).

Soft Skills:

• Rigorous analytical approach to system design and failure root‑cause analysis.
• Ability to document complex technical concepts for cross‑team alignment.

Preferred Add-ons

• Kubernetes SIG contributions (e.g., networking, storage, or scheduling working groups).
• Experience with eBPF‑based tools (Cilium, Pixie) for advanced network observability.
• Proficiency in Python for infrastructure scripting (Ansible/Terraform integrations) or Java for enterprise service interoperability.
• Familiarity with service meshes (Linkerd, Istio) and GitOps pipelines (Argo CD, Flux).
• Knowledge of cloud‑native security (OPA/Gatekeeper, Kyverno) and AI/ML workload optimization.
