Why This Internship

• Engage with open research problems at the frontier of AI systems — challenges that require access to real silicon, large-scale infrastructure, and production data
• Contribute to work intended for publication, with support for presenting results both internally and externally
• Translate research outcomes into real products and next-generation silicon, extending impact beyond publication
• Collaborate with and receive mentorship from senior architects and researchers who will help advance your ideas
• Gain access to advanced infrastructure, tools, and pre-release hardware rarely available in academic settings
• Pursue original, exploratory research directions — independent thinking is actively encouraged
  

What You Can Expect
Focus: Explore how tomorrows AI networks will behave at scale — using simulation to study scale-up and scale-out protocols, congestion, and the interplay between workloads, fabrics, and hardware before they ever reach silicon.
Key Responsibilities

• Investigate emerging scale-up and scale-out protocols and how they perform under real AI workloads
• Explore and extend simulation platforms to model networking and congestion-control behavior at scale
• Experiment with AI-scale and LLM-serving simulation, and workload/trace-driven modeling (e.g., Astra-Sim, Chakra, htsim)
• Study and evaluate protocol performance, scalability, and resilience across topologies
• Correlate simulation results with architectural and hardware behavior to uncover new insights
  

What Were Looking For
Eligibility: Enrolled in a PhD, MS by Research, or MTech by Research program in Computer Science, Computer Engineering, electronics or Electrical Engineering or a related field.
Requirements

• Strong fundamentals in computer networks, transport protocols, and distributed systems
• Curiosity about large-scale simulation and a desire to work with frameworks such as Astra-Sim, Chakra, htsim, ns-3, gem5, or SST
• Understanding of scale-up/scale-out fabrics, RDMA, or congestion control — or eagerness to go deep
• Programming in C++ and Python
  

Preferred: Interest in LLM-serving and AI-workload simulation, next-generation datacenter networking, protocol design, or large-scale performance analysis.

Interview Integrity
To support fair and authentic hiring practices, candidates are not permitted to use AI tools (such as transcription apps, real-time answer generators like ChatGPT or Copilot, or automated note-taking bots) during interviews.
These tools must not be used to record, assist with, or enhance responses in any way. Our interviews are designed to evaluate your individual experience, thought process, and communication skills in real time. Use of AI tools without prior instruction from the interviewer will result in disqualification from the hiring process.
