2027 Summer Intern, MS/PhD, AI-driven ML Performance Engineering Intern

AI in this role

ai-agents

Waymo is an autonomous driving technology company with the mission to be the world's most trusted driver. Since its start as the Google Self-Driving Car Project in 2009, Waymo has focused on building the Waymo Driver—The World's Most Experienced Driver™—to improve access to mobility while saving thousands of lives now lost to traffic crashes. The Waymo Driver powers Waymo’s fully autonomous ride-hail service and can also be applied to a range of vehicle platforms and product use cases. The Waymo Driver has provided over ten million rider-only trips, enabled by its experience autonomously driving over 100 million miles on public roads and tens of billions in simulation across 15+ U.S. states.

We are a team that tdesigns and implements the hardware, compiler, and software frameworks for the ML accelerators in Waymo’s custom silicon. The team’s expertise spans all phases of custom accelerator production from architecture through software integration, and leverages Waymo’s decades of experience to optimize the design space for the needs of our autonomous driving software

Waymo interns partner with leaders in the industry on projects that create impact to the company. We believe learning is a two-way street: applying your knowledge while providing you with opportunities to expand your skill-set. Interns are an important part of our culture and our recruiting pipeline. Join us at Waymo for a fun and rewarding internship!

You will:

Work with AI agents to create high performance low-level kernels in a Domain-Specific language for a custom ML accelerator
Ensure functional correctness and numerical accuracy of kernels
Conduct performance analysis of the kernels to identify performance bottlenecks and areas that need improvement
Develop a custom harness to recursively improve kernel generation and remove the need for human involvement

You have:

Currently enrolled in an MS or PhD program in Computer Science, Computer Engineering, Computational Science, or a related quantitative field
Demonstrated track record of using AI agents and harnesses to improve coding performance
Working knowledge of key kernels for transformer inference including performance analysis and optimization
Familiarity with one or more low-level ML accelerator DSLs (CUDA, Triton, Gluon, etc.)

We prefer:

Solid understanding of modern inference accelerator architectures
Fluency in Python and/or C++
Working knowledge of different ML numerical formats and their relative accuracy vs performance tradeoffs

Skills and AI tools this role asks for

AI Agents

Questions you could be asked

How do you decide when an AI agent can act on its own versus asking for approval first?
How would you decide a model or AI system is ready to ship?
Tell me about a time a model underperformed in production. How did you find out, and what did you change?

Adapt your resume

List these exact terms on your resume: AI Agents. An applicant tracking system matches the wording, not the idea.
Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
Lead with what you built, trained or shipped — this role is judged on the AI system itself, not the tools around it.
