Develop and support WPF desktop applications and integrations involving COM interfaces, SQL Server, SignalR and MassTransit.
Contribute solution recommendations and input to technical design and architecture discussions with the Team Lead and WTW’s ResQ engineering and architecture owners, turning product requirements into maintainable, supportable solutions. WTW retains product-wide architectural and policy authority.

Quality and engineering practices:

Review code and provide practical guidance to teammates; share knowledge of the codebase, application behaviour and engineering practices, and maintain technical documentation and runbooks for assigned components.
Design, implement, maintain and execute unit, integration and regression tests, including Ranorex GUI automation for assigned C# components.
Monitor and triage security scan findings for assigned components, remediate issues within the agreed backlog and WTW’s security standards, and escalate shared-component or policy issues to WTW’s security owners.
Use approved agentic coding tools to explore code, trace workflows, draft bounded implementation changes, generate tests and support refactoring; review and verify outputs before adoption, and share practical learning to support the team’s responsible adoption of AI-enabled engineering practices.
