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 the role:\nRay aims to provide a universal API for building distributed applications (e.g. a machine learning pipeline of feature engineering, model training, and evaluation). Data is usually a core element connecting these different stages, and therefore plays a critical role in Ray’s usability, performance, and stability. We are looking for strong engineers to build, optimize, and scale Ray’s Datasets library and data processing capabilities in general.\nAbout the Ray Data team:\nThe Ray Data team currently develops and maintains the Ray Datasets library, which is already powering critical production use cases (e.g. large scale data compaction at Amazon, and ML pipeline at Alibaba). Ray Datasets is a Python library built on top of Apache Arrow and Ray Core (Ray’s C++ backend), and the Ray Data team interacts closely with Ray Core components including the scheduler and the memory & I/O subsystems. The Ray Data team also works closely with Ray’s ML libraries including Train, RLlib, and Serve.\nA snapshot of projects you will work on:\n- Performance of Ray Datasets at large scale (leveraging Arrow primitives, optimizing Ray object manager, etc.)\n- Integration with ML training and data sources\n- Stability and stress testing infrastructure\n- Lead future work integrating streaming workloads into Ray such as Beam on Ray\n- Differentiate Data operations in Anyscale hosted Ray service\nAs part of this role, you will:\nDevelop high quality open source software to simplify distributed programming (Ray)\n\nIdentify, implement, and evaluate architectural improvements to Ray core and Datasets\n\nImprove the testing process for Ray to make releases as smooth as possible\n\nCommunicate your work to a broader audience through talks, tutorials, and blog posts\n\nWe'd love to hear from you if have:\nAt least 5 years of relevant work experience\n\nSolid background in algorithms, data structures, system design\n\nExperience in building scalable and fault-tolerant distributed systems\n\nExperience with data processing, database internals including Spark or Dask (streaming is a plus)\n\nAnyscale Inc. is an Equal Opportunity Employer. Candidates are evaluated without regard to age, race, color, religion, sex, disability, national origin, sexual orientation, veteran status, or any other characteristic protected by federal or state law.","description_format":"text","description_chars":3096,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["MLOps","AI Compute & Inference"],"lifecycle":[{"event":"open","at":"2026-07-28T21:38:41Z"}],"visa":[],"liveness":{"score":35,"band":"fade","label":"Fading","p_open":1,"p_active":0.794,"p_room":0.44,"age_days":79,"expected_fill_days":68,"reasons":["conf:0","velocity","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/anyscale-software-engineer-ray-data","json_url":"https://alion.io/job/anyscale-software-engineer-ray-data.json","meta":{"generated_at":"2026-10-16T21:08:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":1952,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":12971},"rest":"https://alion.io/mcp/rest/get_company?id=12971"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fanyscale-software-engineer-ray-data"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fanyscale-software-engineer-ray-data"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fanyscale-software-engineer-ray-data"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/anyscale-software-engineer-ray-data\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fanyscale-software-engineer-ray-data"}]}
