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.\nWith 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.\nProud to be backed by Andreessen Horowitz, NEA, and Addition with $250+ million raised to date.\nAbout Ray Data Team:\nRay Data is a Python-native data processing engine and a one-stop shop for all AI data processing needs. Ray Data provides performant, first-class integration with cutting-edge AI frameworks using both multimodal and structured data.\nThe Ray Data team develops and maintains Ray Data, building the underlying distributed data processing infrastructure that powers modern AI workloads. We are a team of engineers passionate about solving challenging problems in distributed systems, data processing, and performance at scale. We are looking for exceptional engineers to build, optimize, and scale Ray Data for increasingly complex AI workloads, including multimodal data processing and large-scale batch inference.\nLearn more about how Ray Data enables scalable multimodal AI workloads in Architecting Multimodal Data Pipelines That Scale with Ray.\nAs part of this role, you will:\nDesign, build, and improve the core systems that power Ray Data, with a focus on performance, scalability, and reliability.\n\nDesign and optimize distributed execution across different stages of data pipelines in heterogeneous environments.\n\nBuild data loading and processing solutions for production training and inference workloads.\n\nSolve challenging problems in distributed execution, scheduling, resource management, data partitioning, fault tolerance, and performance optimization.\n\nMake system-level architectural decisions and reason through tradeoffs in areas such as resource allocation, execution models, batch vs. streaming workloads, and consistency and availability.\n\nWork with customers and new-age AI-native companies to understand and solve challenges in scaling their AI workloads.\n\nWe'd love to hear from you if you have:\n6+ years of experience building production-grade software, infrastructure, or developer-facing systems, with strong Python engineering experience.\n\n6+ years of experience personally owning core architectural decisions within a distributed data or compute engine, rather than primarily operating or using a platform someone else designed.\n\nDeep experience with distributed systems internals, such as scheduling, fault tolerance, data partitioning, distributed execution, performance optimization, or database and query engine internals.\n\nA track record of reasoning through system-level tradeoffs and defending architectural decisions, such as batch vs. streaming, static vs. dynamic resource allocation, or consistency vs. availability.\n\nPassion for solving the unsolved problems in large-scale AI infrastructure and building systems that enable the next generation of AI applications.\n\nWhy Anyscale\nWe'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\n\nOur tech is in production at companies like OpenAI, Uber, Spotify, Instacart, and Cruise\n\nWe're backed by Andreessen Horowitz, NEA, and Addition, with $250M+ raised to date\n\nRecent partnerships with Azure, CoreWeave, and Google Cloud are putting AI-native compute directly into enterprise environments\n\nCompetitive salary and equity, plus health/dental/vision coverage (many plans up to 99% employer-covered)\n\nWe offer flexible time off, paid parental leave, and mental health support\n\nAnyscale Inc. is an Equal Opportunity Employer.
