Role Overview

We are looking for a highly skilledStaff Software Engineer (Data Plane) to join the SonicWall Cloud Secure Edge (CSE) team. In this role, you will lead the design and development of high-performance, cloud-nativedata plane systems that power a modern Security Service Edge (SSE) platform.

You will be responsible for building scalable, low-latency traffic processing pipelines that enforce security policies and enable secure, Zero Trust access to applications, SaaS, and enterprise resources from any device, anywhere. This includes evolving a distributed data plane that delivers capabilities such asZTNA, Secure Web Gateway, and VPN-as-a-Service, replacing legacy appliances with high-throughput, cloud-delivered enforcement systems.

 

What You’ll Do

  • Design and buildhigh-performance data plane systems for traffic processing and policy enforcement
  • Developlow-latency, scalable packet processing pipelines handling large volumes of network traffic
  • ImplementL4–L7 inspection, filtering, and enforcement mechanisms
  • Optimize systems forthroughput, latency, and resource efficiency (CPU, memory, networking stack)
  • Drive architectural decisions arounddistributed data plane design and traffic routing
  • Work closely with control plane teams to integratepolicy distribution and enforcement
  • Debug and resolveperformance bottlenecks in production traffic paths
  • Mentor engineers and promote best practices in systems programming and performance engineering

 

What You’ll Bring

  • 6+ years of system/software development experience indata plane or networking systems
  • Strong expertise inGo, Rust, C, or C++, with a focus onconcurrency and performance
  • Proven experience buildinghigh-throughput, low-latency systems
  • Deep understanding ofLinux networking stack (sockets, epoll, TCP/IP internals)
  • Hands-on experience withpacket processing frameworks or techniques (e.g., DPDK, eBPF, XDP, Netfilter, or similar)
  • Strong knowledge ofnetwork protocols (TCP/IP, UDP, DNS, HTTP/HTTPS, TLS)
  • Experience designing and operatingdistributed data plane architectures
  • Familiarity withload balancing, traffic steering, NAT, proxying, and tunneling (IPSec, TLS, QUIC)
  • Understanding ofsecurity enforcement in the data path (firewalling, ZTNA enforcement, DPI, policy engines)
  • Ability to design forscale, resilience, and fault tolerance in traffic-heavy systems
  • Strong debugging and performance-tuning skills in production environments
  • Ability to lead initiatives, mentor engineers, and raise engineering excellence
  • Strong use of AI tools with sound engineering judgment.
