Description
Role Description
Job Title: Senior .NET/C# Developer – Oracle to PostgreSQL Migration Project
Location: Nottingham/ London
Type: Full-time
Experience: 6+ years of relevant experience
Availability: We are looking to onboard immediately; only candidates who are available to start on short notice will be considered.
About The Project
The client is undertaking a strategic transformation of a legacy system built on PHP and Oracle, migrating to a modern architecture using PostgreSQL and .NET (C#). This is not a simple lift-and-shift; the project involves re-engineering over 240 Oracle stored procedures—some highly complex—into performant, maintainable C# code. The new system will coexist with the legacy platform during the transition, requiring careful integration and support for business-as-usual (BAU) operations.
The team is leveraging AI tools to accelerate and enhance the migration process, and are looking for developers who are excited by the opportunity to work at the intersection of legacy systems, modern development, and AI-assisted engineering.
