You are the founding engineer for its data substrate and nightly runtime, working directly with the CTO. You will design the schema, build the ingestion, write the nightly computations the product decides on, and make it correct enough that brands bet real marketing spend on it. The role is roughly 70% data engineering and 30% backend.\n\nWhat you'll build : \n\n- Ingestion pipelines, multi-tenant from multiple async data sources\n\n- Nightly batch computation over millions of events as set-based SQL and dbt models\n\n- A multi-tenant data model where one brand's data never affects another's run\n\n- Backfill, testing infrastructure and replays as designed capabilities\n\n- Vendor integrations built for failure : retries, idempotency, reconciliation\n\nRequirements : \n\n- 4 - 6 years building and operating production systems\n\n- Deep PostgreSQL : schema design, query plans, batch performance on tables in the tens of millions of rows\n\n- Owned a data pipeline in production end to end : ingestion, transformation, reconciliation, serving\n\n- Set-based thinking : multi-step SQL, window functions, percentiles, incremental computation; you've turned raw event or order data into cohort, retention, or funnel metrics\n\n- Production Python, any framework\n\n- You test batch jobs and reconciliations\n\n- Clear written communication\n\n- Able to start within 30 days\n\nNice to have : \n\n- dbt\n\n- Django in production\n\n- AWS Stack : Python, Django, PostgreSQL, dbt, React with TypeScript, AWS.\n\nSkills\nPostgreSQL, Python, Data Engineering, SQL, Data Modeling, Data Build Tool, Schema, AWS","description_format":"text","description_chars":1668,"description_truncated":false,"requirements":{"experience_years_min":4,"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":"2026-10-03T06:04:46Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":2,"expected_fill_days":18,"reasons":["seen:2","win:early"],"computed_at":"2026-10-05T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/applied-retention-data-engineer","json_url":"https://alion.io/job/applied-retention-data-engineer.json","meta":{"generated_at":"2026-10-06T02:21:06Z","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":3503,"day_limit":5000,"remaining_today":1497,"minute_limit":60,"resets_at":"2026-10-07T00:00:00Z"}},"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":19453},"rest":"https://alion.io/mcp/rest/get_company?id=19453"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fapplied-retention-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%2Fapplied-retention-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%2Fapplied-retention-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/applied-retention-data-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fapplied-retention-data-engineer"}]}
