~40 hrs/week
Responsibilities
Develop and automate the core hardware validation framework for Cisco Silicon One ASICs across simulation and CI/CD environments. Collaborate with architecture teams to debug complex hardware/software issues and ensure high product quality for next-generation networking features.
Requirements
Requires 7-12 years of software development experience with strong proficiency in Python, pytest, and system design patterns. Must have a deep understanding of networking fundamentals (L2/L3, QoS, ACLs) and experience working closely with hardware and lab boards.
Full job description
Meet the team
The Cisco Silicon One Bangalore team is at the heart of Cisco's next-generation networking innovation, developing the software, ASICs, and validation systems that power the industry's most advanced networking silicon. The team is building a unified, programmable silicon architecture that serves as the foundation for Cisco's future routing, switching, and AI/ML network infrastructure. Operating with the agility of a startup within Cisco's global ecosystem, the team designs, validates, and delivers high-performance, multi-terabit silicon solutions that enable faster, more scalable, power-efficient, and secure networks for service providers and web-scale customers worldwide.
Your Impact
Develop and enhance the core hardware validation framework for Cisco Silicon One ASICs.
Design and automate end-to-end validation tests across hardware, simulation, and CI/CD environments.
Build scalable, reliable test frameworks using modern software design principles and Python/pytest.
Validate next-generation networking features including packet processing, QoS, ACLs, warm boot, and multi-device topologies.
Collaborate with silicon, SDK, and architecture teams to ensure comprehensive test coverage and early defect detection.
Own hardware smoke and regression testing to maintain high product quality across releases.
Debug complex hardware and software issues, driving root cause analysis and resolution.
Support bring-up and validation of new Silicon One ASICs and networking platforms.
Minimum Qualification
Strong Python and test-automation skills (pytest, CI, large test matrices)
System design expertise — ability to architect large, evolving validation platforms with clear boundaries, interfaces, and ownership
Proficiency in system design patterns — Demonstrated expertise in system design, software architecture, and design patterns, with the ability to evaluate design trade-offs and develop scalable, modular, and reusable software components.
Comfort working close to hardware — lab boards, SerDes, port bring-up, and long-running HW regressions
Experience with complex systems — build/test pipelines, distributed testing, or large-scale validation frameworks
A mindset for quality and ownership — you care that silicon actually works at line rate, not just that code compiles
Preferred Qualification
Experience with Cisco Silicon One SDK, NPL, SAI, traffic generators (TGEN), or carrier/web-scale networking platforms
