🧠 About the company Labs

The company Labs is building the next generation multi-silicon AI cloud and runtime platform to power the world’s most demanding AI workloads. We enable training and inference across NVIDIA GPUs, AMD GPUs, and AWS Trainium, helping AI companies achieve the best performance and economics across heterogeneous hardware. Our mission is to provide high-performance AI computing and Model API services, enabling AI companies, research labs, and enterprises to train, deploy and integrate cutting-edge models at scale.

🛠️ Role Overview

We are seeking a highly motivated Research Engineer Intern to work on Trainium, GPU kernels, and LLM systems optimization. Over a 12–16 week internship, you will own a well-scoped project at the intersection of AI Systems, Compiler and Runtime Optimization, Distributed Training & Inference, GPU/Accelerator Kernel Development, and Large Language Model Infrastructure — taking it from design to working, profiled code running on real hardware. Your work will ship to production or open source and directly impact the performance of AI applications deployed on our platform. Strong interns receive return offers for full-time roles.

🎯 Responsibilities

• Implement and optimize compute kernels for Attention, GEMM, MoE, and quantization on NVIDIA, AMD, or AWS Trainium.

• Build custom operators using CUDA, Triton, ROCm/HIP, or the Neuron SDK with PyTorch/XLA.

• Profile and improve inference performance in vLLM, SGLang, and our custom runtimes — kernel fusion, scheduling, KV-cache and memory optimizations.

• Build benchmarks, chase down performance regressions, and turn profiler traces into concrete speedups.

• Ship code upstream to open-source AI infrastructure projects, with tests and documentation.

✅ Qualifications

• Currently pursuing a BS, MS, or PhD in Computer Science, Computer Engineering, or a related field.

• Solid programming skills in Python and familiarity with C++.

• Understanding of GPU/accelerator architecture fundamentals (memory hierarchy, parallelism, occupancy) from coursework, research, or projects.

• Experience writing CUDA, Triton, ROCm/HIP, or Neuron kernels — class projects and personal projects count.

• Strong understanding of AI frameworks (e.g., PyTorch, Dynamo, LMCache), model architectures and profiling tools (e.g. Nsight, ROCm Profiler, or Neuron Profiler).

• Strong problem-solving skills and the ability to work independently in a collaborative, remote environment.

🌟 Preferred Experience

• Contributions to open-source AI infra projects like vLLM, SGLang, PyTorch, or Triton.

• Familiarity with LLM inference internals — FlashAttention, PagedAttention, continuous batching, speculative decoding, MoE, or quantization.

• Experience with profiling tools (e.g. Nsight, ROCm Profiler, Neuron Profiler, or PyTorch Profiler) and performance debugging on real workloads.

• Publications in top-tier conferences like MLSys, OSDI, SOSP, NSDI, SC, HPCA, or ISCA

🌐 Why Join the company Labs?

• Be part of a visionary team aiming to redefine AI infrastructure and influence the future of multi-silicon AI computing.

• Work on frontier AI infrastructure problems with access to serious hardware — latest-generation NVIDIA GPUs, AMD accelerators, and AWS Trainium at scale.

• Get direct mentorship from engineers from leading institutions and tech companies.

• Competitive internship compensation, a flexible remote work environment, and a fast path to a full-time return offer for top performers.
