Role Overview

We are looking for a highly skilled Staff 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-native data 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 as ZTNA, Secure Web Gateway, and VPN-as-a-Service , replacing legacy appliances with high-throughput, cloud-delivered enforcement systems.

What You ll Do

Design and build high-performance data plane systems for traffic processing and policy enforcement
Develop low-latency, scalable packet processing pipelines handling large volumes of network traffic
Implement L4 L7 inspection, filtering, and enforcement mechanisms
Optimize systems for throughput, latency, and resource efficiency (CPU, memory, networking stack)
Drive architectural decisions around distributed data plane design and traffic routing
Work closely with control plane teams to integrate policy distribution and enforcement
Debug and resolve performance 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 in data plane or networking systems
Strong expertise in Go, Rust, C, or C++ , with a focus on concurrency and performance
Proven experience building high-throughput, low-latency systems
Deep understanding of Linux networking stack (sockets, epoll, TCP/IP internals)
Hands-on experience with packet processing frameworks or techniques (e.g., DPDK, eBPF, XDP, Netfilter, or similar)
Strong knowledge of network protocols (TCP/IP, UDP, DNS, HTTP/HTTPS, TLS)
Experience designing and operating distributed data plane architectures
Familiarity with load balancing, traffic steering, NAT, proxying, and tunneling (IPSec, TLS, QUIC)
Understanding of security enforcement in the data path (firewalling, ZTNA enforcement, DPI, policy engines)
Ability to design for scale, 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.
