At Anyscale https://www.anyscale.com/, we're on a mission to democratize distributed computing and make it accessible to software developers of all skill levels. We’re commercializing Ray https://docs.ray.io/en/latest/, a popular open-source project that's creating an ecosystem of libraries for scalable machine learning. Companies like OpenAI https://thenewstack.io/how-ray-a-distributed-ai-framework-helps-power-chatgpt/, Uber https://www.uber.com/blog/horovod-ray/, Spotify https://engineering.atspotify.com/2023/02/unleashing-ml-innovation-at-spotify-with-ray/, Instacart https://www.youtube.com/watch?v=3t26ucTy0Rs&list=PLzTswPQNepXmLUiL4F_1VHrPcCz1OeILw&index=23&pp=iAQB, Cruise https://www.youtube.com/watch?v=gj0BqvfX_wI&list=PLzTswPQNepXmLUiL4F_1VHrPcCz1OeILw&index=46&pp=iAQB, 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.

Proud to be backed by Andreessen Horowitz, NEA, and Addition https://www.wsj.com/articles/ai-startup-anyscale-adds-99-million-to-andressen-horowitz-led-funding-round-11661254200 with $250+ million raised to date.

About the role

Ray aims to provide a universal API for building distributed applications. To achieve this goal requires a distributed system with high levels of performance and reliability. We're looking for engineers with systems software experience that are interested in contributing to the Ray backend.

About the Ray Core Team

The Ray Core team develops and maintains the Ray C++ backend (e.g., distributed scheduler, language runtime integration, I/O and memory subsystems). We are responsible for the reliability, scalability, and performance of Ray as well as ensuring that Ray provides the right feature set to support higher level libraries and use cases. The team works on a balance of new features / distributed libraries, test infra improvements, debugging, and longer-term architectural improvements to Ray.

A snapshot of projects you can work on:

Optimizing performance of large-scale workloads on Ray

Stability and stress testing infrastructure

Improving fault tolerance (HA)

As part of this role, you will:

Develop high quality open source software to simplify distributed programming (Ray)

Identify, implement, and evaluate architectural improvements to Ray core

Improve the testing process for Ray to make releases as smooth as possible

Communicate your work to a broader audience through talks, tutorials, and blog posts

We'd love to hear from you if have:

At least 2 year of relevant work experience

Solid background in algorithms, data structures, system design

Experience in building scalable and fault-tolerant distributed systems

Knowledge of distributed model training and inference (e.g. tensor parallel, pipeline parallel) is preferred

Knowledge of GPU programming is preferred

WHY ANYSCALE

We're on a mission to make scalable computing effortless. Ray is the AI Compute Engine at the center of some of the world's most powerful AI platforms

Our tech is in production at companies like OpenAI, Uber, Spotify, Instacart, and Cruise

We're backed by Andreessen Horowitz, NEA, and Addition, with $250M+ raised to date

Recent partnerships with Azure, CoreWeave, and Google Cloud are putting AI-native compute directly into enterprise environments

Competitive salary and equity, plus health/dental/vision coverage (many plans up to 99% employer-covered)

We offer flexible time off, paid parental leave, and mental health support
