- Drive architecture decisions across complex systems, functions, locations and organizations.
- Contribute to solution patterns, reusable building blocks, reference architectures and software-engineering practices.

- Good knowledge of Azure Cloud, APIs, integration mechanisms and data technologies.
- Strong architecture and systems-analysis skills across multiple technology domains.
- Ability to work autonomously and translate complex problems into pragmatic, actionable solutions.
- Strong hands-on engineering/delivery background rather than purely governance-focused architecture experience.

- Azure/private-cloud architecture experience.
- Event-driven architecture and Kafka.
- Linux/Java development stack.
- Experience creating reference architectures, architecture positioning papers and technology roadmaps.
