Member of Technical Staff, ML Systems

About the role We’re looking for a motivated LLM Systems Engineer willing to explore new and unconventional inference systems based on emerging hardware. This role is part engineering, part research – you’ll be responsible for searching and prototyping various algorithms suitable for our inference hardware, as well as guiding our hardware team on the product definition. The ideal candidate has a proven track of record of pursuing ML systems research, and is very familiar with industry-standard LLM inference systems. This role will be performed on-site from one of our offices in Santa Clara, CA or Boston, MA. Essential Duties and Responsibilities Prototype and optimize emerging ML inference systems. Develop novel memory models for expandable vRAM. Write efficient GPU kernels for data movement. Perform design-space exploration, implementation, and benchmarking of inference engines, both in simulations and on real hardware. Qualifications MS or PhD in computer systems, ideally with a focus on LLM inference and/or distributed systems. Prior experience contributing to the core LLM inference infrastructures (vLLM, SGLang, TensorRT, etc.). Prior experience in accelerator programming (e.g. CUDA, JAX/Pallas, ROCm). Advanced computer architectures and performance engineering skills is a big plus. Compensation & Benefits Competitive salary commensurate with experience including base salary, incentive-based bonus, and early stage equity grant. Comprehensive benefits including health, dental, vision, and life insurance. Well-equipped, sunny offices in Santa Clara, CA and Boston, MA. Relocation assistance and visa sponsorship. Perks include a daily lunch stipend, 401k match, and more. A collaborative, continuous-learning work environment with smart, dedicated colleagues engaged in developing the next generation of architecture for high-performance computing. The Opportunity Impact: We are tackling a fundamental challenge at the infrastructure layer: unlocking greater AI capability while dramatically improving efficiency. The work we do here compounds across state-of-the-art AI models, systems, and real-world applications. Timing: Joining now means real ownership of the company and meaningful influence over product direction and execution. You’ll work from first principles, move quickly from insight to execution, and see your contributions directly reflected in what we build. Culture: You’ll work alongside a group of people who care deeply about rigor, clarity, and impact. We value thoughtful disagreement, fast learning, and intellectual fearlessness. This is a place where strong ideas shine, curiosity is encouraged, and growth is a daily practice.
