Software Engineer, Infrastructure

Exa is building a search engine from scratch to serve every AI agent. We build massive-scale infrastructure to crawl the web, train state-of-the-art embedding models to process it, and design super high performant vector databases in rust to search over it. If you like compute, we also own a $5M H200 GPU cluster (and soon 5x'ing that) and regularly spin up batchjobs with tens of thousands of machines.

Our Infrastructure Team builds the underlying tooling and infrastructure that powers all Exa's systems. Basically, we need more infra engineers to build the machine that builds the machine so that we can move as fast as possible as an engineering org. That could mean building GPU cluster orchestration in Kubernetes, map-reduce batchjobs on Ray, or the best observability tooling in the world.

• You have experience designing and operating large-scale infrastructure - GPU clusters or large Kubernetes clusters or cloud batchjob systems

• You bring an obsessive mindset — always thinking about reliability, observability, and optimization across the entire stack.

• →

  Build the Kubernetes orchestration on a $20m GPU cluster

• →

  Scale our AWS batchjob system to handle map reduce jobs over 10s of thousands of machines

• →

  Design GPU scheduling software so we max out our cluster utilization

• →

  Build observability into our production systems

This is an in-person opportunity in San Francisco. We are open to sponsoring international candidates (e.g., STEM OPT, OPT, H1B, O1, E3).
