We don’t take the easy route and build from the ground up, controlling every element allows us to create a superior solution. Our open-source implementation is one of the fastest growing data projects on GitHub and has over 30 thousand stars and 100 million downloads to date.\nWe believe data processing should be a seamless experience from working locally on your development machine to an enterprise production environment. There should be one framework to learn for data practitioners, removing the need for rewriting code when going to production. To make that possible, we are building a cloud platform to seamlessly bring locally developed Polars pipelines to production. We are also building a distributed engine for Polars to scale beyond the limits of a single machine, both in the cloud and on-premises.\nHow will you make an impact?\nYou will be working on fundamental components of both the Polars Cloud platform and the Polars distributed query engine. Some of the things you will be working on are designing gRPC / REST api’s, leader election and failover for cluster nodes, replication of distributed query state and more. For these problems, you will cooperate closely with the cloud platform and compute engine teams.\nRequirements\nYou are familiar with Linux and can find what you need in manpages\n\nYou are proficient in async Rust (Tokio)\n\nYou are familiar with distributed systems architecture and implementation\n\nYou prefer simple solutions to complex ones, but know when complex solutions are needed\n\nYou enjoy working across different domains in a small team\n\nBenefits\nAn important role in a high-growth startup allowing plenty of growth opportunities in diverse directions\n\nChance to work with and learn from a small strong technical team passionate about data processing and software engineering\n\nCompetitive salary\n\nStock option package\n\nFlexible working hours\n\nWe're looking for someone who can join us in our Amsterdam office twice a week to collaborate with the team, drive faster development and ideation, and help build our team culture.","description_format":"text","description_chars":2117,"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":["Flexible schedule","Growth opportunities"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Query Engines & Big Data Processing","Open Source Projects & Foundations"],"lifecycle":[{"event":"open","at":"2026-01-06T13:16:42Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.195,"p_room":0.28,"age_days":285,"expected_fill_days":32,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-19T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/polars-platform-engineer-rust","json_url":"https://alion.io/job/polars-platform-engineer-rust.json","meta":{"generated_at":"2026-10-20T00:03:19Z","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":30,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"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":33508},"rest":"https://alion.io/mcp/rest/get_company?id=33508"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpolars-platform-engineer-rust"},{"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%2Fpolars-platform-engineer-rust"},{"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%2Fpolars-platform-engineer-rust"},{"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/polars-platform-engineer-rust\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpolars-platform-engineer-rust"}]}
