Role: Java Developer (Reverse Engineering and Database Workload Specialist)

Location : San Jose, CA, USA or Scottsdale, AZ, USA (On-Site)

Duration: 12+ months

Experience Required:

• 10+ years of experience in Java application architecture
• Deep expertise in database transaction behavior, SQL extraction, and legacy system reverse engineering
• Experience working with global and cross-functional architecture, data, and QA teams

Core Technical Skills:

• Java architecture and large-scale codebase analysis
• JDBC and custom data access layer internals
• ORM frameworks including Hibernate, JPA, or equivalent ORM engines
• Transaction management and behavior decomposition
• SQL analysis including complex joins, subqueries, and transaction units
• Knowledge of distributed database incompatibility patterns for modern platforms (Preferred)
• Ability to analyze long-term legacy systems developed by multiple teams

Primary Responsibilities:

Codebase Analysis

• Analyze Java applications built using JDBC, ORM frameworks, or custom data access layers
• Extract embedded SQL statements and transaction scopes
• Identify implicit transactional assumptions including ordering, locking, isolation levels, retries, and error-handling behavior

SQL Signature Extraction

• Normalize and standardize extracted SQL into reusable and scalable SQL signatures
• Map SQL signatures to tables, columns, and transactional units
• Identify query patterns incompatible with modern distributed databases or Spanner-style schemas

Transaction Behavior Reconstruction

• Reconstruct logical transactions spanning multiple SQL queries
• Rebuild business workflows embedded in the codebase
• Translate system behavior into intent-based data contracts and engineering-ready specifications

Collaboration and Workload Engineering Support

• Work with Oracle architects to validate application runtime behavior
• Work with Spanner architects to assess migration feasibility and incompatibility risks
• Support QA teams in building realistic workload replay artifacts and data dependency maps
• Assist in creating workload signatures, dependency graphs, and replay input artifacts for migration validation

Key Deliverables

• Centralized SQL signature library for extracted queries
• Transaction behavior mapping across applications
• Application-to-data dependency graphs and contract artifacts
• Compatibility risk flags for distributed database migration
• Workload replay input artifacts for QA validation and performance reconstruction

Additional Expectations

• Ability to read and interpret code written by multiple engineering teams over many years
• Strong analytical and troubleshooting skills for transaction decomposition
• High ownership and independence in execution of architecture validation artifacts
• Excellent communication skills for stakeholder alignment and technical feasibility discussions
• Experience working in Agile delivery environments is a plus
