Description

Who We Are At OKX, we believe that the future will be reshaped by crypto, and ultimately contribute to every individual's freedom. OKX is a leading crypto exchange, and the developer of OKX Wallet, giving millions access to crypto trading and decentralized crypto applications (dApps). OKX is also a trusted brand by hundreds of large institutions seeking access to crypto markets. We are safe and reliable, backed by our Proof of Reserves. Across our multiple offices globally, we are united by our core principles: We Before Me, Do the Right Thing, and Get Things Done. These shared values drive our culture, shape our processes, and foster a friendly, rewarding, and diverse environment for every OK-er. OKX is part of OKG, a group that brings the value of Blockchain to users around the world, through our leading products OKX, OKX Wallet, OKLink and more. Responsibilities: Lead the architecture design and core R&D of cloud-native observability, networking, and security products based on eBPF technology. Spearhead kernel-level data collection using eBPF, including but not limited to network traffic, syscalls, and performance events (profiling), and build high-performance data processing pipelines. Conduct in-depth research on the application of eBPF in observability, designing and implementing non-intrusive solutions for distributed tracing, metrics monitoring, and continuous profiling. Explore the application of eBPF in high-performance networking, such as kernel network acceleration, load balancing, and traffic scheduling, and integrate with projects like K8s CNI to provide innovative container networking solutions. Be responsible for the performance optimization and stability of the eBPF agent, addressing compatibility, security, and resource consumption issues across different kernel versions. Track the latest developments in eBPF and related open-source communities (e.g., Cilium, Falco, Pixie), translating cutting-edge technologies into product capabilities to maintain the company's leadership in underlying cloud-native technologies. Act as a technical evangelist in the eBPF domain, responsible for overcoming technical challenges, knowledge sharing, and providing professional training and guidance to the team. Qualifications: Bachelor's degree or higher in Computer Science or a related field, with 8+ years of experience in low-level software or systems development. Proficient in C/C++ or Rust, and skilled in using Golang for developing upper-level control planes or data processing applications. Rich theoretical knowledge and practical experience with eBPF/BPF, familiar with the entire lifecycle of eBPF program development, loading, and verification. Experience with development libraries/frameworks like BCC, libbpf, or Cilium/ebpf is required. In-depth understanding of the Linux kernel, with deep research into at least one module such as the network stack, file system, or process scheduler. Profound understanding of cloud-native observability, familiar with the design principles and implementation of open-source projects like Prometheus, OpenTelemetry, Skywalking, and Pyroscope. Familiarity with the Kubernetes architecture, with in-depth knowledge and practical experience in container networking (CNI), container runtimes (CRI), and the K8s scheduler. Exceptional ability to analyze and solve low-level system problems, adept at using system tools like perf, ftrace, and gdb for performance analysis and debugging. Experience in kernel module development, DPDK/SPDK development, or productization experience in cloud-native networking, security, or observability is a strong plus. Active contributors to open-source communities (e.g., Linux Kernel, eBPF, Cilium) are highly preferred.
