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.

• 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.
