Rust Jobs for Rustaceans

About the Role
We're looking for a Sr. Staff Software Engineer to join our platform convergence team. This is a hybrid role, reporting in the San Jose office 3 days a week.

Key Responsibilities

• Designing and building a low-latency, high-throughput data forwarding plane using Rust, leveraging its async/await model for efficient I/O and service-oriented infrastructure
• Developing distributed, scalable systems with a focus on concurrency, fault tolerance, and messaging
• Implementing and maintaining gRPC-based APIs and services to integrate forwarding plane capabilities with control and orchestration layers
• Optimizing system performance through profiling tools across kernel-space and user-space
• Engaging in code reviews, system design discussions, technical documentation, and mentoring junior engineers

Requirements

• 7+ years of experience with extensive experience coding with Rust, particularly in systems programming and async frameworks like Tokio or async-std
• Proven expertise in building resilient, observable, and horizontally scalable distributed systems
• Strong understanding of Linux fundamentals, including networking, namespaces, sockets, and kernel-user space interaction
• Proficient in container-based environments, Git, CI/CD workflows, and performance instrumentation

What Will Make You Stand Out (Preferred Qualifications)

• Experience with systems languages like C/C++ or Go, particularly in performance-critical environments
• Familiarity with Linux networking stacks, kernel-space technologies (eBPF, XDP, DPDK), bare-metal deployments, Kubernetes networking, service meshes, or observability tools
• Hands-on experience with gRPC, Protobufs, service-oriented architectures, and L2–L4 networking protocols (TCP/IP, UDP, QUIC, VLAN, routing, encapsulations, etc.)
