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:

• Lead analysis and decomposition of a large-scale Oracle system with 15+ years of PL/SQL code — separating business logic, CRUD, and dead code, defining what remains in the database vs what is moved out.
• Own dependency analysis of PL/SQL packages and architect schema decomposition and data ownership across domains — defining which service owns which tables post-migration.
• Own dual-run and dual-write strategies during migration.
• Ensure backward compatibility through additive-only schema changes under production constraints.
• Lead performance tuning, SQL optimization, and execution plan analysis.
• Design and manage hybrid (on-prem + cloud) database topology during live migration, including AWS RDS Oracle with cross-region replication and Direct Connect latency management.

• Own data lineage documentation and audit trail design across migrated services.

   

Project:

• Migration of a monolithic Oracle system — 723+ tightly coupled PL/SQL packages — to a decomposed architecture with gradual dual-run migration and controlled schema evolution in production.
• Redesign of cross-domain dependencies and data ownership model.

• Hybrid on-prem + AWS topology during transition, with Aurora PostgreSQL as the long-term migration target.

   

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 established 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 established database environments.
• Experience with AWS RDS Oracle — TDE encryption at rest, backup/recovery strategy, cross-region replication.
• Familiarity with Aurora PostgreSQL as a long-term migration target from Oracle.
• Understanding of data ownership mapping, data lineage, and audit trail design in the context of domain decomposition.
• GDPR/SOX compliance awareness in database architecture decisions.

What we offer:

• Competitive compensation depending on experience and skills.
• Regular assessments and salary reviews.
• Paid personal days.
• Mental health support program.
• Language classes.
• Flexible working schedule.

What are we looking for?

• Programming: Expert-level in at least one of Python, C++, or Java/Scala, with strong Python regardless (the analytics ecosystem is Python-centric).
• Distributed/large-scale compute: Experience building or operating high-throughput calculation platforms — grid computing, Spark/Dask/Ray, or in-house distributed batch frameworks; profiling and optimising numerical workloads.
• Risk domain: Working knowledge of market risk measures — VaR (historical simulation in particular), P&L vectors, scenario shocks (absolute/relative/log returns), aggregation and netting.
• Data engineering fundamentals: Handling large time-series and position datasets efficiently (columnar formats, partitioning, memory management).
• Engineering practice: CI/CD, automated testing of numerical code (tolerance-based comparison, golden datasets), code review culture.

Nice to have: 

• Experience with HPL/RTPL production and PLA testing.
• Numerical computing depth: numpy/scipy internals, vectorisation, GPU acceleration.
• Experience integrating with quant pricing libraries via C++/Python bindings.

What we offer:

• Competitive compensation depending on experience and skills.
• Regular assessments and salary reviews.
• Paid personal days.
• Mental health support program.
