Cloud Networking Engineer

Job Description We are seeking a Senior Cloud Platform Engineer with a deep specialization in Networking to join our Cloud Operation team. In this role, you will bridge the gap between traditional core infrastructure and modern, software-defined software architectures. You will treat the network as software, designing self-service platforms and automated infrastructure that enable our application teams to deploy securely and efficiently. What You'll Do Architect and operate secure, highly available, and fault-tolerant routing topologies across multiple public cloud ecosystems (e.g. AWS, GCP, AliCloud). Manage global transit routing utilizing standard protocols (such as BGP and IPsec) alongside cloud-native equivalents like AWS Transit Gateway and Direct Connect. Drive cost and performance optimizations by auditing egress patterns, managing traffic distribution, and engineering efficient data pathways. Own the configuration and scalability of advanced Kubernetes network policies, ingress controllers, and CNI plug-ins (e.g., Cilium, Calico). Implement zero-trust security principles through fine-grained network segmentation, end-to-end encryption (mTLS), and secure secret governance. Serve as the top-tier escalation engineer for troubleshooting complex distributed systems incidents that platform generalists or basic AI diagnostics cannot resolve. What You'll Bring Core Capabilities 5+ years of total infrastructure engineering experience, with at least 3 years explicitly focused on designing cloud-scale networks and virtual software-defined infrastructures. Proven track record within a high-growth SaaS or large-scale digital environment operating enterprise production environments. Mastery of TCP/IP, DNS, TLS, NAT, firewalls, and complex distributed routing tables. Advanced hands-on implementation capabilities across major providers (AWS VPC, Transit Gateway, AliCloud, Tencent Cloud, etc.). Strong scripting capabilities in at least one modern language to write controllers, scripts, or operators for network scaling. Expertise with declarative IaC. What Makes You Stand Out Network or cloud specialty certifications (e.g., AWS Certified Advanced Networking, CCNP). Background in network observability tooling (e.g., eBPF, Prometheus, Grafana, VPC Flow Logs analysis).
