Principal Network Simulation Engineer - VLSI

Job Title

Principal Network Simulation Engineer - VLSI

Role Summary

Design and implement simulation models and scenarios for NICs, switches, and future system architectures to evaluate performance, scalability, and fault tolerance. Work on a cross-functional engineering team with network architects, ASIC designers, and software engineers to inform architectural decisions.

Experience Level

Senior-level. Requires 10+ years of relevant experience in network/system simulation, architecture analysis, or related engineering roles.

Responsibilities

Primary responsibilities include building and running realistic network simulations, analyzing results, and delivering actionable recommendations.

• Develop and maintain simulation models for NICs, switches, and system architectures.
• Design and implement simulation motifs and scenarios to represent realistic network workloads and failure modes.
• Create and maintain tools for performance analysis, data collection, and visualization.
• Measure and evaluate performance, scalability, and fault tolerance; analyze architectural trade-offs and optimization strategies.
• Apply software engineering best practices to ensure reliable, efficient, and reproducible simulation outcomes.
• Collaborate with network architects, ASIC/SoC designers, and software teams to validate designs and drive optimizations.

Requirements

The following are required skills and experience. Nice-to-have items are noted separately.

• Must-have: Strong understanding of network architecture and system-level design.
• Must-have: Proficiency in C++ for simulation modeling and Python for analysis and tooling.
• Must-have: Proven ability to analyze architectural trade-offs and optimize system performance.
• Must-have: Experience working effectively in cross-functional engineering teams.
• Nice-to-have: Familiarity with performance visualization tools, large-scale simulation frameworks, and agile development processes.
• Nice-to-have: Prior technical leadership, mentoring, or principal/lead engineer responsibilities.

Education Requirements

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