Job Title
Founding AI Infrastructure Engineer
Salary
Not Disclosed Equity
Company Description
Piris Labs (YC W26) is a San Francisco startup raising a ~$20M seed round to build the full-stack networking layer for AI inference. Led by engineering veterans from Meta and X alongside an MIT physicist, Piris Labs optimizes large-scale model serving by integrating software orchestration with next-generation GPU and networking architectures.
Job Description
As a Founding AI Infrastructure Engineer at Piris Labs, you will architect a high-performance inference platform from the ground up. You’ll solve complex distributed systems problems across the stack, including multi-node serving, intelligent request routing, and GPU orchestration. This is a rare opportunity to define the foundational technology for the future of AI infrastructure.

San Francisco, USA
Why this role is remarkable
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.
And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.
How does this work?
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
She will pick the best candidates from Jack's network.
