Senior Software Engineer – Networking (C/C++, DPDK/VPP)

We're looking for a hands-on Senior Software Engineer – Networking (C/C++, DPDK/VPP) with strong expertise in developing networking software across the data path, control plane, and related infrastructure. You'll design and build forwarding, protocol, and packet-processing components that run in virtualized and containerized environments, integrating hardware and software-based data paths into production systems.This is a highly technical individual contributor role focused on building high-performance networking solutions. You'll work across networking, security, data-path technologies, and cloud-native infrastructure while collaborating with distributed teams across multiple locations and time zones.

Key Responsibilities

• Design and develop networking software across the data path, control plane, forwarding, and protocol layers.
• Build packet processing pipelines and integrate them with hardware-based data paths such as Network ASICs and software-based data paths such as VPP and DPDK.
• Develop and enhance SD-WAN data-path features, including IPsec, firewall, WAN selection, secure web gateway, zone-based firewall, and stateful firewall capabilities.
• Work on DPI, VPN, QoS, and other data-path technologies, with a strong focus on performance and optimized packet processing.
• Develop and integrate networking components in cloud-native environments using Kubernetes, Docker, distributed systems, message buses, and gRPC.
• Integrate and enhance open-source and third-party networking and infrastructure components while independently troubleshooting and improving production systems.

Skills, Knowledge and Expertise

Must-Have Skills

• 5+ years of strong experience developing networking software, particularly data-path, forwarding, or packet-processing components.
• Strong understanding of data center networking and networking stack development.
• Hands-on experience with C/C++, with the ability to write optimized, performance-sensitive code.
• Experience with DPDK, VPP, or similar data-path technologies.
• Experience with networking and security technologies such as IPsec, VPN, DPI, QoS, firewalls, and SD-WAN.
• Experience with Linux/Unix system programming, Kubernetes, and Docker.
• Understanding of distributed systems, message buses, and gRPC.

Nice-to-Have

• Experience with Golang and microservices architecture.
• Experience with programmable packet-processing pipelines and CNF/VNF technologies.
• Experience working with Broadcom or other Network ASICs.
• Experience with CNCF technologies and cloud-native networking.
• Experience integrating networking solutions with security providers such as Zscaler or Palo Alto Cloud NGFW.
