You will take legacy data carrying personal information, move it onto a controlled cloud platform, and prove through reconciliation that nothing was lost or altered on the way. \nThe role suits an ETL engineer who is comfortable working under regulatory scrutiny and who treats evidence of correctness as part of the deliverable.\n\nKey responsibilities\n• Build the extraction, transformation and load jobs against the conversion specifications.\n• Build the reconciliation queries and control totals, covering row counts, control totals and referential integrity.\n• Execute the migration cycles and resolve the defects they raise.\n• Maintain the data lineage record, so every target field can be traced back to its source.\n• Contribute to the source-defect register, logging data quality issues found in the legacy systems.\nExperience and background\n• 3 to 5 years in ETL or data engineering.\n• At least 1 of those years on a migration carrying personal data under a government or regulatory regime.\n• Has worked on a Government Commercial Cloud platform, or an equivalent controlled cloud environment.\nTechnical skills\n• AWS Glue, PySpark and Python for building the migration jobs.\n• SQL at an advanced level across PostgreSQL and legacy platforms, used for extraction and for reconciliation.\nWays of working\nYou use AI coding tools as part of normal development and review all generated code before committing it. You stay accountable for what ships, which matters most where the data is personal and the checks are formal.\n\nSkills\nMicrosoft Azure, PySpark, data quality audits, PostgreSQL, Google Cloud Platform, Data Integration, Conversion technology, Extraction, Data Engineering, Data Lineage, Data Migration, Defect Reporting, AWS Glue, S3, Migration Testing, Control Practices","description_format":"text","description_chars":1900,"description_truncated":false,"requirements":{"experience_years_min":3,"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":"2026-10-14T08:28:00Z"}],"visa":[],"liveness":{"score":45,"band":"ok","label":"Likely open","p_open":1,"p_active":0.476,"p_room":0.945,"age_days":8,"expected_fill_days":14,"reasons":["seen:8","agency","velocity","win:mid"],"computed_at":"2026-10-22T06:10:10Z"},"pay":{"stated_usd_annual":75000,"is_top_pay":false},"html_url":"https://alion.io/job/zenith-infotech-data-migration-engineer-contract","json_url":"https://alion.io/job/zenith-infotech-data-migration-engineer-contract.json","meta":{"generated_at":"2026-10-23T02:10:15Z","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":3579,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":246649},"rest":"https://alion.io/mcp/rest/get_company?id=246649"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fzenith-infotech-data-migration-engineer-contract"},{"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%2Fzenith-infotech-data-migration-engineer-contract"},{"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%2Fzenith-infotech-data-migration-engineer-contract"},{"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/zenith-infotech-data-migration-engineer-contract\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fzenith-infotech-data-migration-engineer-contract"}]}
