Java Engineer 6 Months £483 Inside IR35 As a Java Engineer, you will remediate, stabilise, and modernise Java applications participating in the "Ingres?only" pathway-decoupling data from Ingres to target relational platforms (Oracle/SQL Server) and implementing secure, supportable fixes that reduce risk ahead of March 2027. You'll collaborate with architects, DB specialists, testers, and delivery leads to plan and execute safe change in line with the client MU standards. Key Outcomes * Risk reduction & compliance: Identify and remediate vulnerabilities, unsupported dependencies, and non?compliant Java patterns to meet MU security and data?protection expectations. * Decoupling from Ingres: Refactor Java data access layers and any other necessary application components; supporting migration from Ingres to the agreed target RDBMS. * Quality & Release readiness: Deliver thoroughly tested fixes and enhancements that are verifiable in SIT, E2E/UAT and OAT/NFR phases, supporting traceability and sign?off. * Knowledge transfer: Produce clear documentation and handover notes to run teams. Responsibilities * Analyse Java applications (TBC but likely JSP/Servlets, Spring, JDBC, custom libraries) to map dependencies and Ingres touchpoints. * Design and implement low?risk remediation: data access abstraction, connection?string/driver changes, error?handling hardening, and performance fixes aligned to target database...
