Numerical Technologies LTD is a leading provider of custom software solutions and services specializing in risk, limits, and regulatory capital. Right now, we are looking for a Database Architect/Engineer to join our team.

What you will be doing:

• Work on a large-scale modernization of a complex Oracle system with 15+ years of legacy PL/SQL code spread across hundreds of packages.

• Drive dependency analysis of PL/SQL packages and architectural decisions for system decomposition.
• Design schema decomposition and data ownership across domains.
• Own dual-run and dual-write strategies during migration.
• Ensure backward compatibility through additive-only schema changes under production constraints.

What we’re looking for:

• Strong Oracle Database 19c+ experience.
• Strong PL/SQL (packages, procedures, functions, triggers).
• Oracle performance tuning (Explain Plan, AWR/ASH, indexing, partitioning).
• Large-scale legacy Oracle system experience.
• Experience with database modernization / monolith decomposition.
• Strong understanding of dual-run / dual-write consistency.
• Experience with Flyway or Liquibase.
• Ability to make architectural decisions in complex legacy database environments.
