Principal Engineer Job at Cisco (Bangalore)

Job Description

We are looking for a strategic and technically deep Principal Engineer to lead the evolution of our networking products. This role is at the intersection of high-performance routing, network security, and Artificial Intelligence. You will act as the bridge between our core networking domain and a team of LLM/AI experts to develop intelligent features that enhance security, automate operations, and create new revenue streams for our existing product portfolio. The ideal candidate will leverage their deep understanding of Cisco’s networking DNA to transform how AI and security are delivered at the silicon and software layers.

Job Responsibility

Collaborate with LLM and AI research teams to integrate intelligent capabilities into networking platforms, focusing on predictive analytics, automated troubleshooting, and traffic optimization
Lead the design of next-generation security features (e.g., hardware-accelerated threat detection, AI-driven anomaly detection, and advanced telemetry) to provide a competitive edge and drive additional product revenue
Define the architectural roadmap for high-capacity networking platforms, ensuring they are optimized for both traditional data forwarding and emerging AI-driven workloads
Identify opportunities to monetize AI and security features within existing networking products, translating technical innovations into business value and growth
Oversee the programming of NPUs and ASICs (e.g., SiliconOne, DNX) to support the high-telemetry demands of AI models and the performance requirements of advanced security protocols
Serve as a subject matter expert across business units, mentoring engineers and guiding cross-functional teams through the complexities of hardware-software-AI integration

Requirements

12+ years of experience in networking software, embedded systems, or security architecture, with a consistent track record of delivering complex products
Deep domain knowledge of Cisco networking architectures, IOS-XR/Classic, and the life cycle of Service Provider or Enterprise routing platforms
Strong background in network security, including ACLs, Lawful Intercept, uRPF, Control Plane Policing, and encryption standards
A solid conceptual understanding of LLMs and AI workflows, with the ability to identify how these technologies can be applied to network telemetry and data path optimization
Expert-level proficiency in C or C++
Experience with packet processing, QoS, and traffic management on programmable silicon (e.g., SiliconOne, Broadcom, or similar)
Bachelor’s or Master’s degree in Computer Science, Electronics, or a related technical field

Nice to have

Ability to challenge the status quo and think inter-disciplinarily to solve complex problems
Understanding of market trends and the ability to align technical development with revenue-generating opportunities
Proven ability to work effectively with niche teams (like AI researchers) to translate abstract concepts into production-ready networking features
Excellent skills in articulating technical vision to leadership, customers, and engineering teams
