Senior Kubernetes Platform Engineer (Go/Python)

Senior Kubernetes Platform Engineer (Go/Python) | Hybrid | PST

Location: Hybrid | Pacific Standard Time (PST) Hours

Role Type: Full-Time | Platform Engineering & SRE

About the Role

We are seeking a Senior Kubernetes Platform Engineer to help build, operate, and scale our core Kubernetes platform. This is an engineering-heavy role designed for professionals with deep production ownership and hands-on coding expertise.

In this role, you won't just manage clusters via the AWS Console or basic CLI commands. You will write custom platform automation in Go or Python , build infrastructure tooling, execute zero-downtime cluster upgrades, manage control-plane reliability, and systematically debug complex networking, node condition, and container runtime issues in production.

If you are passionate about Kubernetes internals, cloud-native automation, and continuous platform reliability, we’d love to speak with you.

What You'll Do

• Production Platform Ownership: Operate, scale, and maintain mission-critical, multi-region Kubernetes clusters with strict reliability requirements.
• Platform Automation & Tooling: Write production-grade code in Go or Python using Kubernetes client SDKs (client-go / kubernetes-python) to build custom controllers, operators, and operational scripts.
• Deep Systematic Debugging: Investigate complex control plane, CNI/networking, pod lifecycle, memory pressure, and node-level issues (NotReady, CPU throttling, kubelet hangs).
• Cluster Upgrades & Maintenance: Plan and execute zero-downtime Kubernetes version updates, API deprecation audits, and platform add-on rollouts.
• Observability & Reliability: Define platform SLOs/SLIs, analyze p95/p99 latency, optimize alerting, and lead root-cause analysis (RCA) for production incidents.
• Collaborative Escalation Support: Participate in an engineering on-call rotation, providing tier-3 support and incident response for globally distributed engineering teams.

Required Qualifications

• 3+ years of hands-on experience operating and managing production Kubernetes infrastructure at scale (control plane, networking, ingress, storage, CNI).
• Strong programming fluency in Go (Golang) or Python , with proven experience using official Kubernetes client libraries (client-go or Python kubernetes client).
• Solid understanding of Kubernetes architecture & internals , including kubelet behavior, API server dynamics, etcd, CRDs, node conditions, and resource limits.
• Systematic Troubleshooting Skills: Demonstrated ability to debug complex, multi-layer distributed system incidents using application logs, distributed tracing, network metrics, and observability tools.
• SRE & Production Support: Practical experience with production on-call rotations, incident handling, MTTR/MTTD analysis, and writing post-mortems.
• Strong Concurrency Concepts: Practical understanding of concurrent programming models in Go (Goroutines/Channels) or Python (asyncio, multiprocessing, multithreading).

Nice to Have

• Experience developing custom Kubernetes Operators or CRDs (using kubebuilder or controller-runtime).
• Advanced container networking experience (e.g., Cilium, Calico, eBPF, or Service Meshes like Istio).
• Experience leveraging AI tools/agents to accelerate development and incident response workflows.

What We Offer

• Scale & Impact: Build and maintain high-impact infrastructure supporting business-critical workloads.
• Modern Stack: Work directly with cutting-edge cloud-native technologies and custom platform tooling.
• Flexible Work Model: Hybrid working environment (2 days a week in the office) aligned with Pacific Time Zone (PST) hours.
• Competitive Compensation & Growth: Continuous opportunities to solve challenging distributed systems problems alongside global engineering talent.
