About the job

Sesame is building a new kind of computer focused on making voice agents a part of our daily lives, aiming for lifelike interactions. We are seeking an ML Model Serving Engineer to enhance our serving layer, which handles a variety of LLM, speech, and vision models. This role involves partnering with ML infrastructure and training engineers to create a fast, cost-effective, accurate, and reliable serving layer for a new consumer product. You will modify and extend LLM serving frameworks, identify opportunities to improve model speed without sacrificing quality, and implement techniques like in-flight batching and caching to accelerate inference and reduce initialization times.

Responsibilities

  • Optimize the serving layer for LLM, speech, and vision models.
  • Collaborate with ML infrastructure and training engineers to build a high-performance serving layer.
  • Modify and extend LLM serving frameworks (e.g., VLLM, SGLang) for high-performance serving.
  • Work with the training team to improve model speed and quality.
  • Implement techniques like in-flight batching, caching, and custom kernels to speed up inference.
  • Reduce model initialization times without compromising quality.

Requirements

  • Expertise in a differentiable array computing framework, preferably PyTorch.
  • Expertise in optimizing machine learning models for reliable, high-throughput, low-latency serving.
  • Significant systems programming experience, including high-performance server systems.
  • Significant performance engineering experience, including bottleneck analysis and profiling.
  • Up-to-date knowledge of the latest model serving optimization techniques.
  • Familiarity with high-performance LLM serving frameworks like VLLM and SGlang.
  • Experience with public cloud platforms (GCP, AWS, Azure).
  • Experience deploying and scaling inference workloads in the cloud using Kubernetes or Ray.
  • Proven ability to ship projects and lead complex, multi-month initiatives independently.
  • Enthusiasm for learning new technologies and working across multiple roles.

Benefits

  • 401(k) with 3.5% employer match
  • 100% employer-paid health, vision, and dental benefits for employee and dependents
  • Unlimited PTO and sick time
  • Flexible spending account with up to $1,650/year employer match
  • Guardian Employee Assistance Program (EAP)
  • Competitive stock options
