Analyse technical requirements and translate them into clear, testable software tasks and specifications
Design, implement and maintain new software features, ensuring solutions are scalable, reusable, maintainable and aligned with functional and non-functional requirements

Review code produced by other engineers, identifying design or implementation issues and helping maintain high software quality
Mentor junior engineers and promote best practice in software design, development, testing and maintainability
Work closely with product, development, automation and Dev Ops teams to support high-quality software delivery

What they're looking for:

Strong commercial record of full stack software development across Web and Windows applications
Strong skills across C# / .Net, ASP.NET, JavaScript, HTML, CSS and SQL Server
Record of developing software for Windows, multiple browsers and mobile-supported environments
Good understanding of software architecture, object-oriented design, maintainable coding practices and software engineering principles
Comfort working across UI, application, integration and data layers
