The posting

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.

WHAT WE OFFER

- $150K/yr – $350K/yr + Offers Equity. We are open to discuss above-scale compensation with exceptional candidates on a case-by-case basis.

- Unlimited PTO and full benefits (medical, vision, dental, 401k).

- Two engineering-centric offices with free parking, private gym, and free lunch, drinks and snacks.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
