Hybrid — 2 days per week from the office.\n\nOwn Caliente's data lake — the system of record for millions of financial events a day (bets, wallet movements, live odds) across 12M+ active users. You decide how that data lands, is stored, retained, and governed on S3 + Snowflake/Databricks, so analytics, finance, and regulators all see accurate, reconciled data with zero drift from source.\n\nKraków, Poland. Hybrid — 2 days per week from the office. \n\nWhat you'll be doing\n\nOwn the lakehouse architecture: bronze/silver/gold layers, Iceberg/Delta tables, schema evolution.\n\nLand operational data via CDC streaming (Kafka, Debezium), handling late and duplicate events.\n\nDesign data layout for speed and cost: partitioning, compaction, file sizing, query performance on Trino/Athena/Snowflake.\n\nOwn retention and archival: storage tiering, regulatory retention, immutability, GDPR deletion.\n\nGuarantee correctness: freshness SLAs, drift detection, reconciliation against the source wallet and ledger systems.\n\nOwn governance: catalog and lineage, row/column access control, PII masking, encryption, audit trails.\n\nMonitor ingestion health, data anomalies, and cloud storage/compute spend.\n\nMust-have\n\nLakehouse architecture — bronze/silver/gold layering, an open table format (Iceberg, Delta, or Hudi), schema evolution.\n\nData layout & query optimization at TB+ scale — partitioning, compaction, file sizing, query performance on Trino/Athena/Snowflake.\n\nCloud lakehouse/DWH in production — Snowflake, Databricks, or BigQuery.\n\nCDC & streaming ingestion — Kafka + Debezium or equivalent; late, duplicate and out-of-order events.\n\nStrong SQL and data modeling — enough relational grounding to reason about the OLTP systems you capture from. Critical for financial ledgers.\n\nCorrectness — freshness SLAs, drift detection, reconciliation against source wallet/ledger systems.\n\nGovernance — catalogs, lineage, row/column access control, PII masking, retention, GDPR deletion.\n\nCloud object storage — S3 or GCS, plus storage tiering and archival.\n\nPython and an orchestrator — Airflow or Dagster, as tools.\n\nNice to have\n\nFintech, iGaming, or another regulated, audit-heavy environment.\n\nCost monitoring / FinOps for storage and compute spend.\n\nHudi specifically; Dagster specifically.\n\nImmutability / WORM regulatory retention.","description_format":"text","description_chars":2336,"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":"2026-10-29T12:21:41Z"}],"visa":[],"liveness":{"score":54,"band":"ok","label":"Likely open","p_open":1,"p_active":0.542,"p_room":1,"age_days":5,"expected_fill_days":24,"reasons":["seen:5","agency","velocity","win:early"],"computed_at":"2026-11-02T06:13:15Z"},"pay":{"stated_usd_annual":96000,"is_top_pay":false},"html_url":"https://alion.io/job/commit-offshore-data-engineer","json_url":"https://alion.io/job/commit-offshore-data-engineer.json","meta":{"generated_at":"2026-11-02T21:13:29Z","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":29617,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":4485830},"rest":"https://alion.io/mcp/rest/get_company?id=4485830"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcommit-offshore-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%2Fcommit-offshore-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%2Fcommit-offshore-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/commit-offshore-data-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcommit-offshore-data-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3453829}},{"tool":"search_jobs","arguments":{"company":"commit-offshore.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3453829},"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); https://alion.io/mcp with an Alion account has everything.
