Advancing the World’s Technology Together

Our technology solutions power the tools you use every day--including smartphones, electric vehicles, hyperscale data centers, IoT devices, and so much more. Here, you’ll have an opportunity to be part of a global leader whose innovative designs are pushing the boundaries of what’s possible and powering the future.

We believe innovation and growth are driven by an inclusive culture and a diverse workforce. We’re dedicated to empowering people to be their true selves. Together, we’re building a better tomorrow for our employees, customers, partners, and communities.

What You’ll Learn

  • Project Overview: Build AgentSysBench, a benchmark suite and profiling toolchain that measures how AI agent frameworks (Claude Code, Aider, LangGraph) use server resources: host CPU, DRAM, GPU HBM and CXL memory. The results will guide memory system design for future AI data centers.
  • Skills You’ll Learn: Profile system and microarchitecture performance with perf, eBPF, hardware PMUs and NVML/DCGM Characterize memory hierarchies (HBM, DDR5, CXL) and build performance models Benchmark LLM inference serving (vLLM/SGLang) on NVIDIA GPU servers

What You’ll Do

Our team researches the next-generation memory solutions for AI workloads, including HBM, DRAM, and CXL memory expansion. This summer, you'll work on servers with Samsung CXL memory expanders and NVIDIA GPUs. You'll see how agentic AI workloads stress memory systems and how those findings feed into future memory product architecture design.

Location: Daily onsite presence at our San Jose headquarters in alignment with our Flexible Work policy

  • Build runtime adapters and a trace record/replay harness for AI agent frameworks
  • Develop micro-kernel and end-to-end agent workload benchmarks that stress CPU, memory, storage and accelerator subsystems
  • Profile agent workloads with perf, eBPF, PMUs and NVML/DCGM to break down per-turn latency and memory bandwidth usage
  • Measure host DDR5, GPU HBM and CXL.mem bandwidth and latency across Intel Xeon and/or AMD EPYC servers
  • Evaluate multi-agent KV-cache sharing and CXL memory expansion on Samsung CXL expanders
  • Build an initial memory tiering cost model (HBM/DDR5/CXL) for long-running MoE agent workloads
  • Present findings in weekly team meetings, then deliver a final report and presentation
  • Complete other responsibilities as assigned.

What You Bring

  • Pursuing PhD in Computer Science, Computer Engineering, Electrical Engineering, or a related field
  • Strong programming skills in Python and C/C++ in a Linux environment
  • Solid understanding of computer architecture (CPU caches, the memory hierarchy, NUMA)
  • Experience with performance profiling tools (perf, eBPF, VTune, or Nsight)
  • Preferred: hands-on experience with LLM serving frameworks (vLLM, SGLang) or GPU programming
  • Preferred: familiarity with HBM, CXL, or heterogeneous memory systems
  • Preferred: experience with AI agent frameworks or benchmark development
  • You’re inclusive, adapting your style to the situation and diverse global norms of our people.
  • An avid learner, you approach challenges with curiosity and resilience, seeking data to help build understanding.
  • You’re collaborative, building relationships, humbly offering support and openly welcoming approaches.
  • Innovative and creative, you proactively explore new ideas and adapt quickly to change.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
