Senior Database Migration Engineer (Oracle & PostgreSQL)

Mactores is the agent-native AWS modernization firm. Most modernization work doesn't ship, it stalls in pilots, slips a year, or lands at three times the budget. We exist to ship it: production systems running, legacy retired, outcomes measured. Our delivery is built on Aedeon, the agent platform built by Mactores' founders' sister company, which absorbs the repetitive 60–70% of engagement work, discovery, dependency mapping, validation, test generation, that traditional consulting bills human hours against. Forward-deployed engineers own the rest: architecture, judgment, and cutover, on dates we commit to in the contract. We are seeking an experienced Senior Database Developer to lead and support Oracle to PostgreSQL/Aurora PostgreSQL migration initiatives. The role involves deep hands-on work across SQL refactoring, schema conversion, DMS operations, performance tuning, and post–go-live stabilization. The candidate will work closely with application teams, cloud engineers, and stakeholders to ensure a smooth, performant, and compliant migration.
