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 databases.
* Collaborate with DBAs to plan and validate schema/data migration and optimise SQL queries post?migration.
* Build and execute test plans with QA: unit/functional/regression, non?functional (reliability, performance), and defect lifecycle management across SIT, E2E/UAT and OAT.
* Contribute to release documentation and change approvals; support rehearsals and cutovers where needed.
* Work within the clients governance for security, data protection, and auditability; keep artefacts current (design notes, runbooks, KT packs).
* Participate in agile ceremonies; coordinate with Actian Exit streams and Model Office activities.
Essential Skills & Experience
* Strong Java: Core Java, JDBC, JSP/Servlets, Spring Framework, and integration with legacy systems.
* Legacy remediation in regulated environments: diagnosing runtime faults, dependency drift, and security gaps; implementing safe, minimal?change fixes.
* Database fluency: experience moving away from Ingres or similar RDBMS; comfort working with DBAs on schema, queries, and performance while preserving behaviour.
* Quality engineering: practical test design, defect triage, and readiness for multi?phase test models (SIT/E2E/UAT/OAT).
* Delivery habits: version control (Git/TFS), lightweight design documentation, and effective stakeholder communication. Experience working in a Scrum and Kanban environment using Test-Driven Development and Pair Programming.
* Flexibility: ability to adapt to different approaches (AI-assistance etc.) and technologies as required.
* Traits: Innovative thinking and strong problem-solving skills.
Desirable
* Awareness of Actian Exit remediation pathways and the specific Java services in scope.
* Familiarity with AI?assisted upgrade accelerators and technical proving approaches used in the programme.
* Experience with the clients MU governance, SD&T/implementation forums, or Model Office validation.
