Learn more about GovTech at tech.gov.sg TradeNet is Singapore's National Single Window for trade permit processing. It handles over 9 million permit applications annually and accounts for around 10% of national tax revenues. We are replacing the decades-old legacy system with a modern, cloud-native platform. The database work is the sharp end of this programme. Years of permit history, reference data, and business rules sit in legacy tables and stored procedures that were never fully documented. All of it has to move — correctly, provably, and without an outage window that agencies or traders would notice. Once it has moved, it has to hold up under sustained volume with clearing deadlines that don't wait for a slow query. You are the person the programme relies on for this. You own the migration approach, the operational health of the estate, and the standards squads follow when they touch data. Teams here use AI-assisted development workflows daily, including LLM/agentic-AI tooling for spec building, code generation, and test automation. You are expected to push the boundaries of what's possible with these tools. [What you will be working on] Legacy Data Migration Own the migration of legacy production data end to end: extraction, transformation, loading, reconciliation, and cutover. You write and run the scripts, not only the plan. Build the reconciliation tooling that proves the migrated data is correct — row counts, financial sums, referential integrity, and business invariants checked on both sides. Design and execute phased cutovers using dual-write, backfill, and shadow-read approaches, with a rollback path you have rehearsed. Work out what legacy data means before you move it, by reading stored procedures, triggers, constraints, and the table relationships nobody wrote down. Execute complex phased cutovers using a 'Co-existence' model for user cohorts, prioritizing batch-based migration over integrated strangler patterns to minimize legacy dependency risks. Perform detective work to reverse-engineer undocumented business logic from legacy Oracle stored procedures and triggers before migration. Performance and Tuning Find and fix slow queries. Read execution plans, correct the bad ones, and tell the owning squad what to do differently next time. Own indexing across the estate: add what's needed, remove what isn't, and watch the write cost. Tune instance and server configuration — memory, work_mem, checkpoints, autovacuum, parallelism, connection limits. Diagnose contention under production load: lock waits, long-running and idle-in-transaction connections, deadlocks, hot rows. Own connection pooling and pool sizing, table and index bloat, vacuum strategy, and partitioning of large history tables. Do capacity planning and cost tuning. Right-size instances and storage instead of scaling up by reflex. Database Operations and Reliability Own backup and recovery,
