- Define system and module boundaries, set architectural direction, and develop high-level interfaces for new capabilities.
- Drive continuous improvement by identifying opportunities for system simplification, refactoring, and process optimisation.
- Guide engineering teams in building robust testing frameworks, ensuring adequate coverage across unit, integration, and end-to-end testing.
- Contribute expertise in architecture, coding practices, development processes, and tools to product teams.
- Ensure cohesion and interoperability across the entire product suite.
Your skills, experience and beyond:
- Expert in AI/ML principles, multiple programming languages, and Service-Oriented Architecture (SOA).

- Skilled in designing scalable, stable, and cohesive architectures across software, infrastructure, and data.
