Job description

As a Full Stack Engineer, you will work closely with the existing engineering team and business stakeholders to design, build and enhance operational tooling and business-critical applications supporting index computation and review processes. You will develop modern front-end solutions using Angular alongside backend services and APIs using C#/.NET, taking ownership of delivery from initial requirements and solution design through development, testing and production.

You will enhance existing applications, introduce new features and help design new applications and workflows, while maintaining strong engineering standards around code quality, unit testing and maintainability. You will also take responsibility for testing your own work and work closely with QA and business teams to support UAT and ensure solutions are delivered successfully.
