build YAML-driven pipeline configs; handle Piper staging/user_staging quirks.\n\n- Own CI/CD for pipelines via standard Git workflows.\n\n- Use internal stack day-to-day : OneETL for pipeline authoring, Piper/uWorc for scheduling, Databook for lineage, uSecret for credentials, DSW notebooks for CSV/table work, SourceGraph for code search, Query Builder for ad hoc SQL.\n\n- Document data models and pipeline logic for maintainability, keeping compliance/audit needs in mind.\n\nWhat We're Looking For : \n\n- 6+ years in data engineering.\n\n- Strong data architecture and system design skills to make sound tradeoffs on modeling, partitioning, and scalability.\n\n- Demonstrated end-to-end production ownership of data pipelines from design through deployment, monitoring, and operational support.\n\n- Expert-level Python + SQL as the primary toolset.\n\n- Robust data quality and auditability practices - validation, reconciliation, anomaly detection, audit trails.\n\n- Experience working with finance, risk, or compliance data.\n\n- Proven experience designing and building transaction/fact tables.\n\n- Strong Python (pandas, SQLAlchemy, type hints/dataclasses, class-based pipelines).\n\n- Airflow-like orchestration experience.\n\n- Solid data modeling fundamentals (fact/dim, normalization, medallion architecture).\n\n- YAML-based config experience; standard CI/CD and Git workflows.\n\nSkills\nData Engineering, Python, SQL, Data Modeling, ETL, MySQL, PostgreSQL, Data Architect, Apache Airflow","description_format":"text","description_chars":3369,"description_truncated":false,"requirements":{"experience_years_min":6,"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":["IT Consulting & Digital Transformation","IT Outsourcing & Dedicated Teams","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-10-23T08:31:20Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":4,"expected_fill_days":36,"reasons":["seen:4","velocity","win:early"],"computed_at":"2026-10-28T05:59:10Z"},"pay":null,"html_url":"https://alion.io/job/nineleaps-senior-data-engineer-2","json_url":"https://alion.io/job/nineleaps-senior-data-engineer-2.json","meta":{"generated_at":"2026-10-28T08:04:34Z","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":10403,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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":1578},"rest":"https://alion.io/mcp/rest/get_company?id=1578"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnineleaps-senior-data-engineer-2"},{"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%2Fnineleaps-senior-data-engineer-2"},{"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%2Fnineleaps-senior-data-engineer-2"},{"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/nineleaps-senior-data-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnineleaps-senior-data-engineer-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3141342}},{"tool":"search_jobs","arguments":{"company":"nineleaps.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3141342},"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);
