• Use AI coding assistants and modern SaaS/cloud tooling to accelerate analysis, prototyping, delivery, and continuous improvement.
• Partner closely with architects, application owners, engineers, and business stakeholders, acting as an advocate for users.
• Enhance adoption of the Architecture Repository and its data through hands-on analysis, documentation, training, community engagement, and proactive stakeholder support.
• Identify and manage upstream and downstream dependencies, and design data governance controls.
• Drive cross-domain toolchain integration and facilitate understanding and adoption of the Engineering Domain Model.
• Continuously improve the platform, operating model, and user community by learning from internal customers, support teams, vendors, and industry trends.

WHAT YOU'LL BRING:

• Proven experience identifying business and user problems, shaping solution options, and delivering practical end-to-end outcomes.
• Strong hands-on engineering capability across solution design, scripting/coding, configuration, integration, data handling, and operational tooling.
• Strong product management skills, with the ability to define and communicate a clear product vision and roadmap.
• Strong stakeholder management and community leadership skills.
• Deep understanding of Architecture, modern engineering practices, DevSecOps, IT service management, and data governance.
