About the role
We file this job under ML Engineer, by the work the posting describes.
ML engineers put machine learning models into products. They write the code that trains, ships, serves and monitors models so a recommendation or prediction works for real users.
Postings ask for strong Python and software engineering, a framework such as PyTorch, cloud services, and more and more often experience with large language models.
A data scientist often works out which model to build; an ML engineer makes it run reliably in production.

Job description
Position Overview
We are seeking an ML Systems Engineer to optimize the performance and efficiency of large language model inference powering our agentic AI platform. This is a technical role focused on low-level systems optimization. You will implement performance optimizations, build evaluation harnesses, and architect multi-node clusters for training and inference that push the limits of LLM throughput and latency. Your work will directly impact the responsiveness and cost-efficiency of AI agents used by leading semiconductor companies to design chips.
Key Responsibilities
Design, deploy, and optimize LLM inference systems across multi-node clusters, maximizing throughput and minimizing latency for production workloads.
Implement and benchmark concrete inference optimizations.
Profile and analyze inference bottlenecks at the systems level—from GPU kernel execution to memory bandwidth constraints.
Build robust evaluation harnesses and benchmarking frameworks that measure accuracy, throughput, latency, and resource utilization across various parallelism strategies.
Collaborate with research scientists to integrate new model architectures and optimizations into production inference infrastructure.
Investigate and apply emerging techniques from research papers and open-source projects to continuously improve inference performance.
Qualifications
B.S., M.S., or PhD in Computer Science, Electrical Engineering, or a related field (or equivalent experience).
Experience with large-scale ML systems, GPU computing, or high-performance inference optimization.
Strong proficiency in Python and C++/CUDA; hands-on experience with SGLang, vLLM, PyTorch, or similar inference frameworks.
Deep understanding of GPU architecture, memory hierarchies, and parallel computing paradigms.
Experience deploying and optimizing LLMs in production: model serving, batching strategies, distributed inference, or quantization.
Strong systems-level debugging and profiling skills; comfort working at multiple layers of the stack from CUDA kernels to application logic.
Familiarity with distributed computing frameworks (Ray, multi-node training/inference) is a plus.
Self-directed problem solver who is interested in working on ambitious optimization challenges.
Why Join Us
Work on cutting-edge LLM inference optimization problems with real-world production impact.
Access to substantial GPU compute resources for experimentation and benchmarking.
Collaborate with a world-class team spanning AI research, systems engineering, and EDA.
Shape the performance characteristics of AI systems used by leading semiconductor companies.
