The role focuses on converting database objects, optimizing migrated workloads, and supporting application teams during migration and cutover phases.\nThe ideal candidate will design, develop, and optimize PostgreSQL database objects, work closely with application and platform teams, and ensure functional and performance parity between source databases (such as SQL Server or Oracle) and PostgreSQL. This role requires hands-on experience with migration tools, query optimization, and post-migration validation.\nKey Responsibilities:\nMigration Planning & Execution:\nLead the conversion of SQL Server database objects (tables, views, indexes, constraints) to PostgreSQL-compatible syntax and data types.\nConvert SQL Server stored procedures, functions, triggers, and views into PostgreSQL-compliant PL/pgSQL with equivalent functionality.\nAddress migration-specific challenges: case sensitivity, identifier quoting, transaction isolation differences, and procedural language semantics.\nSupport application testing, UAT, and performance benchmarking on PostgreSQL / Aurora PostgreSQL.\nFine-tune PostgreSQL configuration parameters in coordination with DBA/platform teams.\nData Migration & Validation:\nDesign and execute data migration strategies using AWS DMS, AWS Schema Conversion Tool (SCT), and/or custom ETL scripts (Python, pgLoader, etc.).\nConfigure and troubleshoot CDC (Change Data Capture) pipelines for near-zero downtime cutover.\nCollaborate with data engineering/ETL teams to validate data integrity, referential consistency, and volume reconciliation post-migration.\nResolve data type mismatches, truncation issues, and encoding/collation conflicts.\nPerformance Optimization & Cloud Tuning:\nAnalyze query execution plans and refactor migrated queries for optimal PostgreSQL performance.\nDesign and implement effective indexing strategies and leverage PostgreSQL-specific features.\nTune Aurora PostgreSQL parameters and advise on instance sizing.\nBenchmark and stress-test migrated workloads; provide performance sign-off before production cutover.\nAutomation, Support & Documentation\nDevelop and maintain migration automation scripts (SQL, shell, Python, etc.) to streamline conversions and validations.\nProvide L2/L3 support during migration, cutover, and post-go-live phases.\nDocument migration standards, conversion guidelines, and PostgreSQL development best practices.\nMentor internal teams on PostgreSQL development patterns and migration considerations.\nEnsure all migrated objects comply with organizational security and compliance policies.\nPreferred Qualifications:\n4+ years of experience in database development, with at least 3 years focused on PostgreSQL.\nProven track record in large-scale, heterogeneous migrations (SQL Server → PostgreSQL/Aurora PostgreSQL).\nStrong proficiency in:\no PL/pgSQL, advanced SQL (window functions, CTEs, JSON/JSONB)\no AWS DMS, SCT, pg_dump/pg_restore, pgLoader, or similar tools\no Query performance tuning & execution plan analysis\no Version control (Git) and CI/CD integration for database changes (e.g., Liquibase, Flyway)\nFamiliarity with cloud infrastructure (AWS RDS/Aurora, IAM, VPC, security groups).\nExperience with monitoring tools (CloudWatch, pg_stat_statements, pgBadger, Datadog).\nNice-to-Have\nExposure to other source platforms (Oracle, MySQL, Sybase) for a broader heterogeneous migration context.\nKnowledge of database DevOps (GitOps, automated testing, drift detection).\nAWS Certified Database - Speciality or PostgreSQL professional certifications.","description_format":"text","description_chars":3696,"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":["Managed IT Services (MSP)","AI Consulting & Integration","Cloud Consulting & Migration","Data Engineering & Migration Services"],"lifecycle":[{"event":"open","at":"2026-08-29T21:18:52Z"}],"visa":[],"liveness":{"score":36,"band":"fade","label":"Fading","p_open":1,"p_active":0.814,"p_room":0.44,"age_days":79,"expected_fill_days":68,"reasons":["conf:3","velocity","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":30969,"is_top_pay":false},"html_url":"https://alion.io/job/minfy-technologies-senior-database-developer","json_url":"https://alion.io/job/minfy-technologies-senior-database-developer.json","meta":{"generated_at":"2026-10-19T01:25:31Z","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":754,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-20T00:00:00Z"}},"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":59584},"rest":"https://alion.io/mcp/rest/get_company?id=59584"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fminfy-technologies-senior-database-developer"},{"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%2Fminfy-technologies-senior-database-developer"},{"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%2Fminfy-technologies-senior-database-developer"},{"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/minfy-technologies-senior-database-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fminfy-technologies-senior-database-developer"}]}
