Principal Network Simulation Engineer - VLSI

Job Title

Principal Network Simulation Engineer - VLSI

Role Summary

Design and implement system-level simulation models and analysis tools to evaluate NICs, switches, and future network/system architectures. Use simulation results to guide architectural trade-offs for performance, scalability, and fault tolerance.

This role partners with network architects, ASIC designers, and software teams to validate designs and inform product decisions.

Experience Level

Senior / Principal level. The posting requests 10+ years of relevant experience.

Responsibilities

Primary responsibilities include:

• Develop and maintain simulation models for NICs, switches, and system architectures.
• Design and implement realistic simulation motifs and network scenarios.
• Create tools for performance analysis, visualization, and result interpretation.
• 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 guide design decisions.

Requirements

Must-have technical skills and experience:

• 10+ years of professional experience in network/system simulation or related fields.
• Strong understanding of network architecture and system-level design.
• Proficiency in C++ for simulation modeling and Python for analysis and tooling.
• Experience analyzing architectural trade-offs and optimization strategies.
• Ability to work effectively in cross-functional engineering teams.

Nice-to-have:

• Experience with NICs, switches, ASIC/SoC design flows, and performance visualization tools.
• Knowledge of scalability and fault-tolerance analysis methods.
• Familiarity with Agile development practices.

Education Requirements

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