Principal Network Simulation Engineer - VLSI

Job Title

Principal Network Simulation Engineer - VLSI

Role Summary

Senior engineering role to develop and run system-level network simulations that evaluate NICs, switches, and future system architectures. The engineer will build simulation models and tooling, run realistic network scenarios, analyze performance/scalability/fault tolerance, and communicate results to architects, ASIC designers, and software teams.

Experience Level

Senior — typically 10+ years of relevant simulation, networking, or system-architecture experience.

Responsibilities

Primary responsibilities include building and operating simulation models and delivering actionable analysis.

• Develop simulation models for NICs, switches, and system architectures to evaluate performance and trade-offs.
• Design and implement simulation motifs and scenarios that reflect realistic network workloads.
• Create tools for performance analysis, result visualization, and automated reporting.
• Measure and evaluate performance, scalability, and fault tolerance of proposed architectures.
• Apply software engineering best practices to ensure simulation correctness, reproducibility, and efficiency.
• Collaborate closely with network architects, ASIC designers, and software engineering teams to influence design decisions.

Requirements

Key skills and experience required. Items marked as "nice-to-have" are preferred but not mandatory.

• Must-have: 10+ years of experience in network/system simulation, architectural analysis, or related engineering roles.
• Must-have: Proficiency writing simulation models in C++ and performing data analysis in Python.
• Must-have: Strong understanding of network architecture and system-level design; experience analyzing architectural trade-offs and optimization strategies.
• Must-have: Experience building tooling for performance measurement, visualization, and automated scenario execution.
• Must-have: Strong software engineering practices: testing, version control, and reproducible experiments.
• Must-have: Ability to work effectively in cross-functional teams and communicate technical results clearly.
• Nice-to-have: Experience with distributed or large-scale simulation frameworks, NIC/ASIC internals, or domain-specific performance models.

Education Requirements

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