About Anyscale:
At Anyscale, we're on a mission to democratize distributed computing and make it accessible to software developers of all skill levels. We’re commercializing Ray, a popular open-source project that's creating an ecosystem of libraries for scalable machine learning. Companies like OpenAI, Uber, Spotify, Instacart, Cruise, and many more, have Ray in their tech stacks to accelerate the progress of AI applications out into the real world.
With Anyscale, we’re building the best place to run Ray, so that any developer or data scientist can scale an ML application from their laptop to the cluster without needing to be a distributed systems expert.
We're a San Francisco based company, proud to be backed by $250+ million from top-tier investors like Andreessen Horowitz, NEA, and Addition.
About the role:
Anyscale is looking to hire strong engineers to build next generation high-performance machine learning serving systems (both our open source libraries and SaaS offering).
Much of the tooling used to serve ML models today is inherited from the previous generation of infrastructure, but emerging ML applications come with a new set of requirements: high compute requirements, the need for specialized hardware, and composing many different models along with business logic in a single request.
Our goal is provide a simple but powerful set of tools to make bringing complex ML applications to production a reality.

As part of this role, you will:

  • Building a highly available service for ML model serving
  • Improve Ray Serve and our other libraries to make authoring next-generation production ML applications as easy as possible
  • Improve our autoscaling capabilities to drive performance improvements & cost savings
  • Reduce latency and improve throughput for single- and multi-model serving

We'd love to hear from you if you have:

  • Solid background in algorithms, data structures, system design
  • Experience working with modern machine learning tooling (PyTorch, Tensorflow, JAX)
  • At least 1+ year of relevant work experience

Bonus points!
