* Improve the performance, reliability, and observability of the service (logging, metrics, tracing, alerting).
Architecture & Technical Direction
* Work closely with the Principal Engineer to influence the future architecture of profile management, data contracts, and event schemas.
* Contribute to the design and evolution of domain events, ensuring schema consistency, forward compatibility, and good modelling practices.
* Drive engineering standards across the squad, including testing strategy, CI/CD improvements, and code quality practices.
Collaboration
* Collaborate with product teams across the organisation to integrate Unified Profile into their services and support shared use cases.
* Partner with Platform, Data Engineering, and Security teams to ensure APIs, events, and data flows are compliant, secure, and well-governed.
* Work with frontend and mobile engineers to define clear, well-documented APIs (OpenAPI/Swagger).
Leadership & Mentorship
