Offer description

About the Role

We're looking for a Principal Software Engineer to lead the migration and modernisation of a complex legacy application into a modern, scalable architecture. This is a hands‑on technical role where you'll shape the design, guide the team, and ensure successful delivery of a critical transformation project.


Key Responsibilities

* Drive the migration of legacy systems to modern, cloud‑based solutions.
* Define and implement microservice architecture using a code‑first approach.
* Apply strong architectural principles and design patterns to deliver robust solutions.
* Collaborate with a cross‑functional team (including React developers) to ensure seamless integration of front‑end and back‑end.
* Get hands‑on with C#, .NET, SQL, Web APIs, and React for complex feature development.
* Build credibility through technical expertise and lead the team in pushing designs forward.
* Work on features that require deep integration with multiple third‑party applications.


What We're Looking For

* Proven experience in application modernisation and migration projects.
* Strong background in microservice architecture and design patterns.
* Hands‑on expertise in C#, .NET, SQL, and Web APIs.
* Cloud experience (Azure preferred, AWS considered).
* Knowledge of front‑end technologies (ideally React but not essential).
* Ability to understand and guide front‑end work within the overall architecture.
* Evidence of delivering complex technical solutions and influencing design decisions.
* Excellent communication and leadership skills to inspire and guide a team.


Interview Process

* Introductory Call with the Hiring Manager: review CV, discuss role, answer questions.
* Take‑home Technical Task.
* Face‑to‑Face Interview at the Newcastle office.


Why Join Us?

* Excellent benefits package including an attractive pension scheme.
* Be at the forefront of a major transformation project.
* Work with modern technologies and cloud platforms.
* Hybrid working with flexibility.
* Opportunity to influence architecture and technical direction.
