You will help own that rebuild.This is a hands-on role. You’ll set patterns, write the foundational code, and ship across the stack - from CDC and ingestion through dbt, the semantic layer, and the interfaces that BI tools and AI agents consume.\nJob Responsibilities\nEnd-to-end pipeline work: MongoDB CDC → ingestion → lakehouse → warehouse → dbt → semantic layer → BI/AI consumers\nCo-ownership of architecture decisions with the Data Engineering Lead\nCDC from production MongoDB without degrading operational DB performance; ingestion patterns that make adding a new source a config change, not a project\nOrchestration that’s observable end-to-end (Airflow, Dagster, or Prefect)\nThe dbt project: structure, conventions, tests, contracts, exposures, CI\nThe semantic / metrics layer (dbt Semantic Layer, Cube, or equivalent) - one canonical definition per business metric\nLLM-readiness: column-level documentation, PII tagging, query cost guardrails, materialized metric tables, and evals on AI-generated SQL\nMigration of existing logic out of the Tableau and Metabase sprawl into modeled, governed sources\nJob Qualifications\n4+ years across data engineering and/or analytics engineering - you’ve spent meaningful time on both sides\nComfort spanning the stack: comfortable shipping a Debezium connector one week and a dbt mart the next\nDeep dbt and SQL - you’ve owned a non-trivial project, not just contributed to one\nProduction CDC experience (Debezium, Kafka Connect, Airbyte, or hand-rolled) against operational databases - bonus if that database was MongoDB\nA cloud warehouse you know deeply (Redshift, Snowflake, BigQuery, or Databricks)\nStrong Python; comfortable in Linux, infra-as-code, and CI/CD\nWorking understanding of how LLM tooling (RAG, NL-to-SQL, embedded agents) consumes a data platform - and what breaks when the platform isn’t ready\nStrong opinions on modeling, lightly held; bias toward observability\nBonus:\nMongoDB schema evolution at scale\nProduction semantic-layer rollouts (dbt Semantic Layer, Cube, LookML, MetricFlow)\nLakehouse formats (Iceberg, Delta, Hudi) or streaming experience (Kafka, Flink, Kinesis)\nData catalog / lineage tooling (DataHub, Atlan, Collibra)\nLogistics, marketplaces, or other operationally heavy domains\nEvals on AI-generated SQL or analytical reasoning","description_format":"text","description_chars":2543,"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":[{"name":"Egypt","iso":"EG","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Delivery","Logistics","Courier Services"],"lifecycle":[{"event":"open","at":"2026-09-20T11:30:24Z"}],"visa":[],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.339,"p_room":0.28,"age_days":143,"expected_fill_days":33,"reasons":["conf:1","stale_co","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/bosta-senior-data-engineer","json_url":"https://alion.io/job/bosta-senior-data-engineer.json","meta":{"generated_at":"2026-10-16T23:07:12Z","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":4932,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":7150},"rest":"https://alion.io/mcp/rest/get_company?id=7150"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fbosta-senior-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%2Fbosta-senior-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%2Fbosta-senior-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/bosta-senior-data-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fbosta-senior-data-engineer"}]}
