The listing
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.
What you will do?
- Analyze and remediate large enterprise Java codebases — replace legacy and database-specific SQL constructs with modern, standards-compliant SQL.
- Convert embedded SQL in Java services and MyBatis XML mappers: rewrite vendor-specific functions, sequences, pagination logic, dynamic SQL, and error-handling patterns.
- Work closely with schema and database migration engineers so application-layer SQL lands aligned with the modernized target schema.
- Refactor Java transaction logic, error handling, drivers, and ORM/DAO layers to match the behavior of modern databases.
- Run unit, integration, and performance testing to confirm functional parity and hit performance SLAs post-modernization.
- Support production cutover — validation, monitoring setup, rollback planning, and stabilization until the system holds.
- Produce engineering documentation that outlives the engagement: SQL remediation guides, code-migration runbooks, troubleshooting guides, and knowledge-transfer material for customer teams.
- Work across distributed teams (US and India) and with customer SMEs to keep business logic aligned and the modernization on track.
