Job Title:Senior Oracle Developer – Oracle to .NET (C#) Migration Project 

Location: Nottingham

Type: Full-time

Experience: 5+ 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 modernising a long-standing enterprise system built on PHP and Oracle, transitioning to a modern .NET (C#) architecture. A key focus of this transformation is the migration of a large and complex Oracle database, which includes over 240 stored procedures and extensive embedded business logic. The existing Oracle database will be migrated to Postgres or MySQL and testing this will be critical.

Key Responsibilities

Analyse, maintain, and optimise the existing Oracle PL/SQL codebase throughout the migration. Translate and refactor Oracle stored procedures and other database logic into efficient and maintainable C# code. Work closely with software engineers and business analysts to accurately capture and re-implement business logic in the new architecture. Troubleshoot issues arising from differences in execution behaviour between PL/SQL and .NET environments. Support the creation of migration plans, technical documentation, and testing strategies to ensure parity and quality. Assist in managing a hybrid Oracle/.NET environment during phased rollout. Contribute to BAU operations and the stability of the legacy system while migration activities are underway.

 Required Skills & Experience

5+ years of experience developing in Oracle PL/SQL, including deep knowledge of stored procedures, triggers, and packages. Proven experience in migrating business logic from Oracle to .NET (C#), with a focus on re-architecture rather than direct translation. Strong understanding of Oracle internals and how database logic integrates with external systems. Experience migrating data from Oracle to other databases especially Postgres/MySQL. Ability to work collaboratively in a cross-functional team environment. Strong problem-solving ability and attention to technical detail. Excellent communication skills, with the ability to document and explain complex systems clearly.
