• Understand high‑level features and desired outcomes (both now and future).
• Assist team building, understanding and analysing desired outcomes.
• Responsible for the application‑level outcomes, prioritisation and maintaining a roadmap of capability improvements in conjunction with the Senior Leadership Team.

• Verify implementation to validate consistency with the agreed architecture and meet desired outcomes.
• Manage change to the software architecture and control software complexity.
• Make software architecture and solutions as flexible as possible.

• Proven experience in leading teams and developing architectures.
• Experience designing enterprise architecture with modern technologies (cloud computing, CI/CD, virtualization, agile design and development, REST services, standards‑based authentication and authorisation protocols).
• Experience collaborating with cybersecurity, product owners, users and developers to design and communicate an innovative and secure architecture that enables continuous delivery of software.
• Experience decomposing monolithic software into manageable pieces, especially in related software domains.
• Experience designing shared services such as caching, eventing and messaging in a distributed environment.
• Extensive Java or C experience, including best‑practice coding, unit testing and source control management.
• Strong communication skills and ability to work independently and/or under supervision.
