Principal Network Simulation Engineer - VLSI

Job Title

Principal Network Simulation Engineer - VLSI

Role Summary

Design and implement high-fidelity network simulations for NICs, switches, and future system architectures to evaluate performance, scalability, and fault tolerance. Provide simulation-driven data and tools to guide architecture and implementation decisions while working with cross-functional engineering teams.

Experience Level

Senior — typically requires 10+ years of relevant experience in network/system-level simulation, architecture analysis, or related VLSI engineering.

Responsibilities

Primary responsibilities include building simulation models, executing realistic scenarios, and delivering analysis to inform product architecture.

• Develop simulation models for NICs, switches, and system architectures.
• Design and implement simulation motifs and realistic network scenarios.
• Create and maintain tools for performance analysis and visualization.
• Evaluate performance, scalability, and fault tolerance of proposed architectures.
• Apply software engineering best practices to ensure reliable, maintainable simulations.
• Collaborate with network architects, ASIC designers, and software engineers to validate design trade-offs.

Requirements

Must-have technical skills and experience. Education details are listed under Education Requirements.

• 10+ years of industry experience in network/system simulation, architecture analysis, or related VLSI work.
• Strong understanding of network architecture and system-level design.
• Proficiency in simulation/modeling with C++ and data analysis using Python.
• Experience analyzing architectural trade-offs and performance optimization strategies.
• Experience building performance analysis and visualization tools.
• Ability to work effectively in cross-functional teams and communicate technical findings.
• Familiarity with software engineering practices for simulation code (testing, version control, CI).

Nice-to-have:

• Experience with ASIC/SoC-level simulation or VLSI design flows.
• Experience with large-scale system or network fault-tolerance simulation frameworks.

Education Requirements

Bachelor's, Master's, or PhD in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field — or equivalent practical experience.
