- Deep understanding of networking fundamentals, especially Layer 2 and Layer 3 protocols
- Experience with Network Operating Systems (SONiC or similar)
- Hands-on experience with ASIC integration, including SAI and vendor SDKs
- Strong knowledge of Linux systems, including kernel and networking stack
- Understanding of high-performance and scalable system design principles
- Advanced debugging and problem-solving across distributed and low-level systems
- Ability to design and implement scalable, high-performance networking solutions
- Strong analytical thinking and ability to troubleshoot complex issues
- Effective cross-functional collaboration with hardware and software teams
- Ability to translate architecture into implementation with strong attention to detail
- Operates as a technical leader, influencing design and architectural direction
- Demonstrates strong ownership and accountability for business-critical systems
- Ability to work independently with minimal guidance on ambiguous problems
- Strong mentorship and knowledge-sharing mindset
- Focus on quality, scalability, and long-term maintainability
- Comfortable working in a fast-paced, innovation-driven environment
Responsibilities
- Design, develop, and enhance core NOS components, including control plane and data plane functionality
- Implement and optimize Layer 2 and Layer 3 networking protocols (e.g., routing, switching, VXLAN, EVPN)
- Integrate and work closely with ASIC vendors (e.g., Broadcom, Marvell) using SAI/SDK interfaces
- Contribute to SONiC-based or similar open networking platforms
- Debug and resolve complex issues spanning hardware, kernel, and user-space components
- Analyze and optimize system performance, scalability, and reliability in high-speed networking environments (100G/400G+)
- Participate in system architecture and design discussions, providing technical leadership and direction
- Collaborate cross-functionally with hardware, platform, and validation teams to ensure seamless integration
- Drive end-to-end ownership of features, from design through deployment and support
- Mentor junior engineers and contribute to overall team technical growth
- Contribute to best practices in coding, design, and system-level troubleshooting
