Job Description

• Day-to-Day Responsibilities
• On a day-to-day basis, you will join a team responsible for developing and modernising a critical cloud-based platform supporting FTSE Russell's indexing and analytics business. Working as a Senior Full Stack Developer, you will be responsible for delivering new features, maintaining existing applications, supporting production incidents, and driving key application modernisation initiatives.
• You will develop and support applications using C# .NET, Angular, SQL Server, RESTful APIs, and AWS cloud technologies, working across both backend and frontend components.
