• Developing scalable APIs, services and cloud-based solutions within an AWS environment.


• Working with modern versions of .NET, alongside React, PostgreSQL and Microsoft SQL Server.


• Getting involved across the development lifecycle, from solution design and coding through to deployment and operations.


• Collaborating closely with other engineers through pairing, code reviews and technical discussions.


• Helping the team increase its focus on new product development by improving processes and reducing maintenance overhead.


• Using AI-assisted development tools, with Claude currently the team's primary choice, to make development more efficient and the codebase easier to work with.


• Working closely with product and wider teams to turn customer and business requirements into practical technical solutions.
