Senior ML Systems Engineer Inference (LLM)

In short

This senior role leads end-to-end LLM serving performance work for large-model GPU deployments, covering benchmarking, profiling, and runtime optimization. The company builds inference offerings and needs someone to diagnose serving-stack bottlenecks and improve single-node and multi-node inference efficiency. Requires 5+ years of system engineering experience, hands-on work with vLLM/SGLang or similar serving engines, strong Python skills, and GPU profiling expertise.

About the Role
You will lead end-to-end LLM serving performance work. You will define rigorous performance measurements, diagnose bottlenecks across the serving stack, improve efficiency for large models on GPU deployments, and turn findings into reliable production runtimes and configurations. You will collaborate on inference offerings, evaluate emerging ecosystem tools, and implement runtime fixes.
Requirements
•5+ years of professional system engineering experience
•Production or serious benchmark-scale experience with vLLM, SGLang, or a comparable serving engine
•Strong Python software engineering skills
•Understanding of LLM inference performance, batching, memory, parallelism, latency, and throughput
•Experience with quantization, speculative decoding, or distributed serving
•Benchmarking, performance analysis, and GPU profiling skills
•Clear written communication of results and decisions
Responsibilities
•Define rigorous, repeatable inference-performance measurements
•Profile and diagnose serving-stack performance problems
•Improve serving efficiency for large models on single-node and multi-node GPU deployments
•Create production-ready runtimes, configurations, and defaults
•Shape inference offerings with product and infrastructure stakeholders
•Evaluate, adopt, build, and contribute to inference ecosystem projects
•Trace serving-engine bottlenecks and implement fixes
Benefits
•Equity through stock options
•Medical, dental, and vision plans
•Flexible PTO
•Remote-first work
•$1,200 home office and equipment stipend
