Software Engineer- Simulation Models
About The Position
We develop advanced simulation platforms and digital twins that mirror complex IOS-XR routing environments for scalable, high-fidelity network validation. Our team bridges the gap between software engineering and field deployment by automating CI/CD testing pipelines and providing robust virtualization tools for developers and customers. We are dedicated to pioneering the future of network reliability through high-speed simulation, ensuring seamless performance across the most demanding service provider infrastructures. You will define, design, develop, test, debug, release, enhance, and maintain software that accelerates the development of Cisco IOS XR and SONiC. You will lead the implementation and optimization of simulation software and tools, develop digital twins for routing and artificial intelligence (AI) fabric products, and build large-scale distributed systems. In this role, you will apply advanced theoretical and practical knowledge to create functional, system-level models for next-generation routing platforms. You will also have opportunities to contribute to open-source technologies and communities.
