Principal Network Simulation Engineer - VLSI

Job Title

Principal Network Simulation Engineer - VLSI

Role Summary

The Principal Network Simulation Engineer develops and validates simulation models for network interface controllers (NICs), switches, and emerging system architectures to inform ASIC and system design decisions.

This role partners with network architects, ASIC designers, and software engineers to drive realistic performance, scalability, and fault-tolerance analyses and produce actionable recommendations for architecture and implementation trade-offs.

Experience Level

Senior — requires 10+ years of relevant experience in network/system simulation, architecture analysis, or related fields.

Responsibilities

Primary responsibilities include building and using simulation frameworks to evaluate network architectures and guiding design decisions.

• Develop simulation models for NICs, switches, and future system architectures.
• Design and implement simulation motifs and scenarios that reflect realistic workloads.
• Create tools for performance analysis, visualization, and result interpretation.
• Evaluate performance, scalability, and fault tolerance of proposed architectures and subsystems.
• Apply software engineering best practices to ensure reproducible, efficient, and maintainable simulations.
• Collaborate closely with network architects, ASIC designers, and software teams to translate requirements into simulation objectives and interpret results.
• Document findings and present recommendations to technical stakeholders.

Requirements

Must-have technical skills, experience, and attributes.

• Proven experience developing simulation models and frameworks for network hardware or system-level components.
• Strong understanding of network architecture and system-level design.
• Proficiency in C++ for simulation modeling and Python for analysis and scripting.
• Experience analyzing architectural trade-offs and optimization strategies.
• Experience creating performance analysis and visualization tools.
• Familiarity with software engineering best practices: version control, testing, and CI for simulation code.
• Ability to work effectively in cross-functional teams and communicate technical results clearly.

Nice-to-have: experience with ASIC/NIC hardware, large-scale network simulation, and fault-tolerance modeling.

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.
