Principal Network Simulation Engineer - VLSI

Job Title

Principal Network Simulation Engineer - VLSI

Role Summary

Design and deliver high-fidelity simulation models and performance analysis for NICs, switches, and system-level network architectures. Provide data-driven evaluation of performance, scalability, and fault tolerance to inform ASIC and system design decisions.

Work on a cross-functional engineering team with network architects, ASIC designers, and software engineers to prototype architectures and communicate results to technical stakeholders.

Experience Level

Senior level — Principal role. The posting specifies 10+ years of relevant experience.

Responsibilities

Primary responsibilities include:

• Develop and maintain simulation models for NICs, switches, and future system architectures.
• Design and implement simulation motifs to drive realistic network scenarios and workloads.
• Create tools for performance analysis, data processing, and visualization.
• Evaluate performance, scalability, and fault tolerance; quantify architectural trade-offs.
• Apply software engineering best practices to ensure reliable, reproducible simulation results.
• Collaborate with network architects, ASIC designers, and software teams to validate designs and communicate findings.

Requirements

Must-have technical skills and experience:

• Strong understanding of network architecture and system-level design.
• Proven experience building simulation models and frameworks (production-grade C++ preferred).
• Proficiency in Python for data analysis, scripting, and visualization.
• Experience analyzing architectural trade-offs and optimization strategies for networked systems.
• Track record of working effectively in cross-functional teams and communicating technical results to stakeholders.
• Demonstrated software engineering practices: testing, version control, performance profiling, and automation.

Nice-to-have:

• Experience with VLSI/ASIC design flows, NIC or switch microarchitecture, or system-level co-design.
• Familiarity with performance visualization tools and large-scale simulation platforms.

Education Requirements

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