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.

About the Role

vLLM is growing at a fast pace, and every bit of that growth lands on the CI system. More models, more hardware, more contributors, more ways for things to break. Your job is to make sure none of that slows anyone down.

You’ll get to:

• Maintain and scale the compute infrastructure that powers CI, release, performance benchmark, accuracy evaluation for vLLM project, across a wide range of models and accelerators including H100/H200, (G)B200/300, AMD MI325/355X, TPU, Intel Gaudi, etc..

• Get creative about cutting CI time-to-signal from hours to minutes

• Make sure every corner of vLLM code base is well-tested

• Keep vLLM releases rock-solid

• Build out tooling that helps 3,000+ vLLM contributors move fast
