Java Architect

Description :

Java Architect / Reverse Engineering ExpertReverse engineer embedded SQL and transactional behavior from 1000+ Java applications and convert them into testable data contracts and workload signatures. This role is critical for pre-model validation.Codebase Analysis

• Analyze Java applications using : oJDBCoORM frameworksoCustom data access layers
• Extract embedded SQL and transaction scopes.
• Identify implicit assumptions : oOrderingoLockingoIsolationoRetry behaviorSQL Signature Extraction
• Normalize SQL into reusable signatures.
• Map signatures to : oTablesoColumnsoTransaction units
• Identify query patterns incompatible with Spanner.Behavior Reconstruction
• Reconstruct : oLogical transactions spanning multiple queriesoBusiness workflows embedded in code
• Translate behavior into intent-based contracts.Collaboration
• Work with Oracle architects to validate runtime behavior.
• Work with Spanner architects to assess feasibility.
• Support QA in creating realistic replay workloads.Required Skills & Experience
• 10+ years of Java application architecture
• Expert in : oJDBCoTransaction managementoORM internals (Hibernate / JPA)
• Strong SQL knowledge (complex joins, subqueries)
• Experience reverse engineering large legacy systems
• Ability to read code written by many teams over yearsKey Deliverables
• SQL signature library
• Transaction behavior maps
• App-to-data dependency graphs
• Compatibility risk flags
• Input artifacts for workload replay#LI-SP3#LI-VX1
