£483
This role is ideal for someone who thrives in a collaborative environment, enjoys solving complex technical challenges, and is passionate about delivering impactful public sector solutions.
Role Purpose
As a Senior VB6 Engineer, you will remediate, stabilise, and modernise VB6 applications participating in the "Ingres?only" pathway-decoupling data from Ingres to target relational platforms (e.g., 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 standards.
Key Outcomes
- Risk reduction & compliance: Identify and remediate vulnerabilities, unsupported dependencies, and non?compliant VB6 patterns to meet clients security and data?protection expectations.
- Decoupling from Ingres: Refactor data access; support migration from Ingres to the agreed target RDBMS while retaining VB6 UI where required.
- 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 the clients live support teams.
Responsibilities
- Analyse VB6 applications (forms, modules, class libraries, COM components) to map dependencies (ADO, ODBC, custom DLLs/OCXs) 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 DB engineers to plan and validate schema/data migration and to optimise SQL (procs/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 MU governance for security, data protection, and auditability; keep artefacts current (design notes, runbooks, KT packs).
- Participate in agile ceremonies; coordinate with the Actian Exit streams (ETMP, Data Retention, Low?Code, Ingres?only) and Model Office activities.
- Coach junior engineers and contribute to the clients MU engineering community initiatives.
Essential Skills & Experience
- Strong VB6: forms, modules, class modules, COM/ActiveX, API calls, ADO/ODBC.
- 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.
