VB6 Engineer

Inside IR35, £530 P/D

3 monthly rolling contract (Expected to last 12-15 months)

Hybrid, 1-2 days on site per week in Telford

Active SC would be advantageous

As a VB6 Engineer, you will remediate, stabilise, and modernise VB6 applications decoupling data from existing databases to target relational platforms (e.g., Oracle/SQL Server) and implementing secure, supportable fixes. You'll collaborate with architects, DB specialists, testers, and delivery leads to plan and execute safe change in line with client standards.

Key Outcomes

Risk reduction & compliance: Identify and remediate vulnerabilities, unsupported dependencies, and non compliant VB6 patterns to meet 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 live support teams.

Responsibilities

Analyse VB6 applications (forms, modules, class libraries, COM components) to map dependencies (ADO, ODBC, custom DLLs/OCXs) and legacy database 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 governance for security, data protection, and auditability; keep artefacts current (design notes, runbooks, KT packs).
Participate in agile ceremonies; coordinate with the other programme streams and Model Office activities.
Guide engineering best practices across squads, including code quality, security, and performance.

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
