Network Design Engineer, AIHPC

About Groq

Inference is the engine that powers AI and Groq was built from the silicon up to deliver the worlds fastest inference at scale. We pioneered the LPUthe first processor designed specifically for AI inferenceand are transforming that innovation into a global cloud platform powering production AI workloads.

With the capital infrastructure and team to execute were uniquely positioned to define the next era of AI infrastructure. The opportunity is massive and its still wide open. Now lets go build it!

Mission:

Groq is building high-performance AI infrastructure designed to make inference fast predictable and scalable. Our infrastructure teams design and operate the systems that connect compute data and services at significant scale. We are looking for a Sr./Staff Network Engineer AI/HPC to help architect design validate and evolve the network infrastructure supporting Groqs rapidly growing AI compute environments.

As a Sr./Staff Network Design Engineer you will own network architecture and design across high-performance data center and AI infrastructure environments. You will translate capacity performance reliability and business requirements into scalable network designs that can be deployed and operated consistently.

This role requires deep expertise in data center networking routing protocols network architecture automation and large-scale infrastructure. You will work closely with network operations data center engineering compute platform security and infrastructure teams to take designs from concept through validation and production deployment.

You will also help establish the engineering standards design patterns tooling and technical direction that allow Groqs network infrastructure to scale.

In this role success means building network architectures that allow Groqs infrastructure to grow without sacrificing performance reliability or operational simplicity. You will create repeatable designs rather than one-off solutions automate wherever practical identify scaling limits before they become production problems and make the network an enabling layer for Groqs compute infrastructure.

Youll combine deep networking expertise with a systems engineering mindsetconsidering not only whether a network works but how it behaves at scale how it fails how it is validated and how efficiently it can be operated.

Location: This role will be based in one of our three hiring hubs: the Dallas San Francisco or New York City area . The person hired for this role must be based in one of these three areas. Youll have the flexibility to work remotely while we establish our local Groq office with the expectation that this role will transition to onsite once the office opens.
