The environment is highly technical and collaborative, involving close interaction with multiple scrum teams across design, development, and testing. You will contribute to evolving critical components such as protocol stacks, kernel-level networking, SD-WAN, and high-availability systems. This is a hands-on engineering role where performance, reliability, and innovation directly impact millions of end users. It is ideal for engineers who enjoy deep system-level work and solving challenging distributed networking problems.

In this role, you will design, develop, and enhance high-performance networking and security features within a large-scale firewall platform. You will contribute across the full software development lifecycle, ensuring quality, scalability, and reliability of mission-critical systems.

• Design and develop network security features aligned with product architecture and performance goals
• Work on L2–L7 networking components including protocol stacks, kernel-space data paths, and security modules
• Define and execute unit, system, and integration testing strategies, ensuring high code quality
• Participate in peer code reviews, design discussions, and technical evaluations across teams
• Analyze requirements, identify gaps, and propose optimized technical solutions in collaboration with product teams
• Drive improvements in engineering practices, design patterns, and development standards
• Collaborate closely with QA, product management, and other engineering teams to deliver robust solutions
• Contribute to troubleshooting, debugging, and resolution of complex system-level issues
