You will work at the intersection of distributed systems, storage, and machine learning infrastructure, designing and building high-throughput pipelines, operating large-scale workflows, and optimizing training-time performance. This is a systems role that requires a strong ownership mindset, comfort with performance and storage efficiency, and experience with distributed systems or large-scale data pipelines.\nMissions\nDesign and build high-throughput pipelines for data ingestion and processing, ensuring validation, transformation, and featurization of raw multimodal data.\nOperate large-scale batch and streaming workflows over massive datasets, optimizing dataloaders, sharding, prefetching, caching, and throughput to reduce time from data arrival to model training.\nCollaborate with cross-functional teams to translate evolving data needs into robust systems, ensuring operational correctness and implementing observability, validation, and guardrails to prevent silent data regressions.\nProfil recherché\n - Familiarity with batch and/or streaming processing systems- Ownership mindset: design, build, operate, and iterate on systems end-to-end\n- Comfort reasoning about performance, memory, I/O, and storage efficiency\n- Enjoy working closely with researchers and unblocking fast-moving projects\n- Experience building distributed systems or large-scale data pipelines\n- Experience with object storage systems and data format tradeoffs\n- Strong software engineering fundamentals\n- Experience with large ML training pipelines or dataloading systems\n- Knowledge of columnar or custom data formats\n- Experience with systems like ClickHouse, Ray, Flink, Spark, or similar\n- Debugging and fixing performance bottlenecks in data-heavy systems\n- Hands-on experience operating petabyte-scale datasets","description_format":"text","description_chars":1969,"description_truncated":false,"requirements":{"experience_years_min":null,"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":[],"lifecycle":[{"event":"open","at":"2026-10-07T13:30:05Z"}],"visa":[],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.335,"p_room":0.28,"age_days":76,"expected_fill_days":21,"reasons":["conf:0","velocity","win:tail","crowd:"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/p-ml-infra-engineer-data-systems","json_url":"https://alion.io/job/p-ml-infra-engineer-data-systems.json","meta":{"generated_at":"2026-10-11T03:55:49Z","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","counted_by":"address","units_charged":1,"used_today":2084,"day_limit":5000,"remaining_today":2916,"minute_limit":60,"resets_at":"2026-10-12T00:00:00Z"}},"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":3908685},"rest":"https://alion.io/mcp/rest/get_company?id=3908685"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fp-ml-infra-engineer-data-systems"},{"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%2Fp-ml-infra-engineer-data-systems"},{"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%2Fp-ml-infra-engineer-data-systems"},{"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/p-ml-infra-engineer-data-systems\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fp-ml-infra-engineer-data-systems"}]}
