Our platform runs patented machine learning models across billions of consumer signals in real time, optimising campaigns toward outcomes like purchase intent, brand lift, and foot traffic rather than proxy metrics like clicks. The result is 2-5x better performance than industry benchmarks, at scale.\nWe operate a high-load programmatic infrastructure, processing millions of ad requests per second with sub-200ms response times globally. This isn’t a layer on top of someone else’s stack; it’s built from the ground up, in-house, by the team you’d be joining. Founded in 2012 and headquartered in London, we now have 400+ people across 19 cities and have sustained 40% revenue CAGR since 2018. The engineering problems here are real, the ownership is genuine, and the scale is significant.\n\nThe opportunity\nYou own the build and ongoing maintenance of our internal data lakehouse, giving our users the data they need to make better-informed, data-driven decisions. Today our data lives across BigQuery, Clickhouse, Postgres, and Elastic Search, and internal users rely on product reporting or ad hoc extracts in Rill, Tableau, and Looker.\n\nWhat you’ll do\nOwn the build and maintenance of our internal data lakehouse.\nPartner with our Product team to identify the core platform data that Finance and Business Development need.\nAnalyse and organise raw data from our different sources.\nBuild and maintain the data pipeline architecture that exposes data from our databases into our visualisation tools.\nDevelop data systems and pipelines that keep data efficiently updated.\nImprove data quality and reliability.\nPartner with other engineers to maintain our tooling and pipelines.\n\nWhat you’ll bring\nEssential\nYou bring 3+ years of experience in a data engineering role.\nYou bring experience with database technologies including BigQuery, Clickhouse, and Postgres.\nYou bring technical expertise with data models, data mining, and segmentation techniques.\nYou bring experience with Airflow and/or dbt.\nYou bring experience with cloud-based technologies running on GCS and/or AWS.\nNice to have\nExperience with Snowflake\nAnalytical skills for working with unstructured datasets\n\nWhat we offer\nHybrid working - flexible schedule · 1 month work-from-anywhere · Annual performance bonus · Multikafeteria (sport/culture card) · LoopMe Gives Back · Learning & development support","description_format":"text","description_chars":2510,"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","Hybrid work"],"hiring_locations":[{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Sales & Marketing","AI Agents","Digital Marketing"],"lifecycle":[{"event":"open","at":"2026-10-23T07:41:02Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":8,"expected_fill_days":58,"reasons":["conf:0","win:early"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/loopme-data-engineer","json_url":"https://alion.io/job/loopme-data-engineer.json","meta":{"generated_at":"2026-11-01T19:55:08Z","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":30647,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":2680733},"rest":"https://alion.io/mcp/rest/get_company?id=2680733"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Floopme-data-engineer"},{"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%2Floopme-data-engineer"},{"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%2Floopme-data-engineer"},{"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/loopme-data-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Floopme-data-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3139748}},{"tool":"search_jobs","arguments":{"company":"loopme.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3139748},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
