Inference Engineering, Co-op

Inferact · Research & Engineering

Where: San Francisco
Posted: Sep 15

Inferact's mission is to grow vLLM as the world's AI inference engine and accelerate AI progress by making inference cheaper and faster. Founded by the creators and core maintainers of vLLM, we sit at the intersection of models and hardware, a position that took years to build.

What you'd do

Location: San Francisco, California. This co-op is in-office only at Inferact's San Francisco office and is intended for the University of Waterloo co-op program.
Work term: Co-op / internship. Exact dates will align with the applicable Waterloo work term.
Compensation: Competitive compensation based on the applicable co-op market and candidate background, plus a housing stipend for the duration of the co-op term.

What they want

Currently pursuing a bachelor's, master's, or PhD degree in computer science, engineering, mathematics, or a related technical field, and eligible for a University of Waterloo co-op work term.
Strong programming ability in Python, C++, Rust, Go, or another systems-oriented language.
Strong computer science fundamentals and the ability to learn from research papers, technical documentation, and complex systems code.
Evidence that you have built and debugged nontrivial software through coursework, research, a prior internship, open-source work, or an ambitious side project.
A builder mindset: you define what success means, measure results, validate correctness, communicate clearly, and keep iterating until the system works.

About Inferact · Research & Engineering

We're looking for exceptional University of Waterloo co-op students who want to work on the systems that determine how fast, efficiently, and reliably frontier AI models run on frontier workloads at scale. This is not a sandboxed internship project. We will match your strengths and interests to a real engineering problem across the vLLM stack, from model execution and low-level accelerator code to distributed serving and the cloud platform that makes it all usable. You'll work alongside the cre…
