Job Description

Senior .NET/C# Developer

Oracle to PostgreSQL Migration: Our client is embarking on a strategic transformation of a legacy enterprise platform, rebuilding a long-standing PHP and Oracle-based system into a .NET (C#) and PostgreSQL architecture.

Seeking talented developers who are excited to work at the intersection of legacy systems, modern architecture and cutting-edge development tooling.

Your Responsibilities:

* Re-engineer Oracle PL/SQL logic into performant and maintainable C# services.
* Design and build .NET components that interact with both PostgreSQL and legacy PHP systems.
* Work closely with BAs and stakeholders to ensure functional parity and identify areas for modernisation or optimisation.
* Contribute to the design and delivery of a hybrid system architecture supporting phased rollout.
* Leverage AI tools to assist with code analysis and migration.
* Participate in code reviews, contribute to testing strategies and support comprehensive documentation efforts.

What You'll Bring:

* Experience developing in .NET/C#, particularly in backend and data access layers.
* Proven success migrating legacy systems, especially from Oracle to PostgreSQL or similar.
* Strong working knowledge of Oracle PL/SQL and the ability to translate procedural logic into C#.
* Solid experience with PostgreSQL, including handling dialect differences and performance tuning.
* Comfortable working in hybrid environments where legacy and modern platforms coexist.
* Familiarity with AI-enabled tools that accelerate development and migration tasks.
* Strong grasp of software architecture principles, design patterns, and integration techniques.
* Collaborative mindset with excellent communication skills.

Nice to Have:

* Experience with legacy PHP platforms and their integration challenges.
* Familiarity with CI/CD pipelines and DevOps workflows.
* Exposure to microservices, domain-driven design or event-driven architecture.
* Background in agile delivery.

Please note: This is an initial 6 month contract, deemed inside IR35 and predominantly remote working with the ability to attend the London office as and when required.
