• Work on networking features across the data plane, control plane, and system-management layers.
• Develop and enhance firewall, authentication, and encryption, access-control, and threat-protection capabilities.
• Investigate and resolve complex issues involving performance, concurrency, memory usage, networking, and system stability.
• Analyze packet flows and troubleshoot network-protocol behavior using tools such as Wireshark and tcpdump.
• Optimize software for throughput, latency, scalability, and resource-constrained environments.
• Participate in architecture discussions, technical design reviews, and code reviews.
• Develop unit, integration, and system-level tests to ensure product quality and reliability.
• Collaborate with hardware, QA, product-management, security-research, and customer-support teams.
• Contribute to secure-development practices throughout the software-development lifecycle.

• Experience using Git and working within a collaborative code-review and continuous-integration environment.
• Ability to independently own complex features from design through implementation, testing, and production support.
• Strong written and verbal communication skills.

Preferred Qualifications

Experience developing firewalls, routers, VPN gateways, intrusion-prevention systems, secure-access products, or other network-security appliances.

Knowledge of stateful firewalling, NAT, routing, policy enforcement, traffic inspection, and session management.
