ML Model Serving Engineer

Responsibilities:

• Turbocharge our serving layer, consisting of a variety of LLM, speech, and vision models.
• Partner with ML infrastructure and training engineers to build a fast, cost-effective, accurate, and reliable serving layer to power a new consumer product category.
• Modify and extend LLM serving frameworks like VLLM and SGLang to take advantage of the latest techniques in high-performance model serving.
• Work with the training team to identify opportunities to produce faster models without sacrificing quality.
• Use techniques like in-flight batching, caching, and custom kernels to speed up inference.
• Find ways to reduce model initialization times without sacrificing quality.

Required Qualifications:

• Expert in some differentiable array computing framework, preferably PyTorch.
• Expert in optimizing machine learning models for serving reliably at high throughput, with low latency.
• Significant systems programming experience; ex. Experience working on high-performance server systems—you’d be just as comfortable with the internals of VLLM as you would with a complex PyTorch codebase.
• Significant performance engineering experience; ex. Bottleneck analysis in high-scale server systems or profiling low-level systems code.
• Always up to date on the latest techniques for model serving optimization.

Preferred Qualifications:

• Familiarity with high-performance LLM serving; ex. experience with VLLM, SGlang deployment, and internals.
• Experience with a public cloud platform such as GCP, AWS, or Azure.
• Experience deploying and scaling inference workloads in the cloud using Kubernetes, Ray, etc.
• You like to ship and have a track record of leading complex multi-month projects without assistance.
• You’re excited to learn new things and work in a multitude of roles.

Full-time Employee Benefits:

• 401 (k) max employer match: 3.5% of compensation
• 100% employer-paid health, vision, and dental benefits for you and your dependents
• Unlimited PTO and sick time
• Flexible spending account with employer matching up to $1,650/year (medical FSA)
• Guardian Employee Assistance Program (EAP)
• Opportunity to share in the company's success with competitive stock options

Benefits do not apply to contingent/contract workers.
