About the Role

We are looking for a Senior Software Engineer (SDE III) who will build, profile, and optimize GPU workloads powering next-generation generative AI experiences — from Stable Diffusion image generation to transformer-based multimodal models.
You’ll work closely with research and infrastructure teams to make model inference faster, more cost-efficient, and production-ready.

This role is ideal for engineers passionate about pushing GPUs to their limits, writing high-performance kernels, and turning cutting-edge research into scalable systems.

Key Responsibilities

  • Develop, optimize, and maintain GPU kernels (CUDA, Triton, ROCm) for diffusion, attention, and convolution operators.
  • Profile end-to-end inference pipelines (data movement, kernel scheduling, memory transfers) to identify and resolve bottlenecks.
  • Apply techniques like operator fusion, tiling, caching, and mixed-precision compute to maximize GPU throughput.
  • Collaborate with researchers to productionize experimental layers or model architectures.
  • Build benchmarking tools and micro-tests for latency, memory, and throughput regressions.
  • Integrate kernel improvements into serving stacks, ensuring reliability and repeatable performance.
  • Work with platform teams to tune runtime configurations and job scheduling for GPU utilization.

Required Qualifications

  • 4+ years of experience in systems or ML engineering, with 2+ years working on GPU or accelerator optimization.
  • Strong hands-on skills with CUDA programming, memory hierarchies, warps, threads, and shared memory.
  • Familiarity with profiling tools (Nsight, nvprof, CUPTI) and performance analysis.
  • Working knowledge of PyTorch, JAX, or TensorFlow internals.
  • Proficiency in C++ and Python.
  • Experience with mixed precision, FP16/BF16, or quantization.
  • Deep curiosity about system bottlenecks and numerical correctness.

Preferred Qualifications

  • Experience building fused operators or integrating custom kernels with PyTorch extensions.
  • Understanding of NCCL / distributed inference frameworks.
  • Contributions to open-source GPU or compiler projects (Triton, TVM, XLA, TensorRT).
  • Familiarity with multi-GPU / multi-node training and inference setups.

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.

How do you know if you have a disability?

A disability is a condition that substantially limits one or more of your “major life activities.” If you have or have ever had such a condition, you are a person with a disability. Disabilities include, but are not limited to:
