About the Role We are looking for a highly experienced Senior Platform Engineer to join our Edge Platform team. This role combines systems engineering, software development, and cloud-native infrastructure. You will be responsible for designing, building, and operating the software and platform capabilities that power our distributed edge computing infrastructure across Galleon mobile data centers and Commander cloud services. You will work extensively with Linux, Kubernetes, distributed systems, networking, and automation while developing platform components and operational tooling in Go and Python. The ideal candidate is equally comfortable debugging kernel-level performance issues, writing production-quality software, and designing resilient cloud-native platforms. This is a hands-on engineering role focused on building platform capabilities rather than solely operating infrastructure. What You'll Do Platform Engineering & Software Development Design, develop, and maintain platform services, controllers, operators, and automation frameworks using Go and Python. Build internal tools and APIs that simplify provisioning, lifecycle management, observability, and operations of edge infrastructure. Develop software to automate infrastructure workflows, hardware lifecycle management, cluster operations, and fleet-wide orchestration. Contribute to platform architecture, technical standards, and engineering best practices. Design and implement self-healing and autonomous operational capabilities. Linux Systems Engineering Debug and optimize Linux systems across compute, storage, networking, and container workloads. Investigate complex performance issues involving CPU scheduling, memory management, I/O subsystems, networking, filesystems, and containers. Analyze kernel and userspace behavior using tools such as perf, eBPF, strace, tcpdump, bpftrace, and system profiling utilities. Drive platform reliability through deep understanding of Linux internals and operating system behavior. Participate in root cause analysis of production incidents involving operating systems, containers, and distributed systems. Kubernetes & Cloud Platform Architect, deploy, and manage highly available Kubernetes environments across edge and cloud infrastructure. Build and maintain Kubernetes operators, controllers, CRDs, admission webhooks, and platform extensions. Implement scalable networking, storage, security, and observability solutions for Kubernetes. Optimize cluster performance, resource utilization, and workload scheduling in resource-constrained edge environments. Drive Infrastructure-as-Code initiatives using Terraform, Ansible, Helm, and GitOps methodologies. Reliability & Operations Design and maintain observability platforms using Prometheus, Grafana, OpenTelemetry, and centralized logging solutions. Establish operational excellence through automation, monitoring, incident response, and postmortem processes. Collaborate with software, infrastructure, security,
