Carry out impact assessments for proposed changes, considering architectural principles and design standards.

Work closely with Enterprise, Solution and Data Architects, Product Owners, Business Analysts and Test Analysts.

Support solutions throughout the full product and project lifecycle, from inception through delivery, operations, support and eventual decommissioning.

Contribute to architecture governance and ensure solutions remain scalable, reliable and secure.

What you'll bring:

Strong experience developing and delivering solutions using Microsoft Azure and supporting cloud technologies.

Experience working as a Solution Architect, Solution Designer or in a comparable technical architecture role.

Strong understanding of cloud and hosted infrastructure concepts.

Experience translating complex business requirements into clear technical solutions.

Experience working in fast-paced Agile environments.

Experience working with system integrators and external technology vendors, including teams operating across different organisations and geographies.

Experience reviewing vendor solution and design documentation against architecture principles and standards.

Proficiency using Enterprise Architecture tools and modelling languages such as UML and ArchiMate.

Experience using Azure DevOps or equivalent issue and project management tooling.

Strong understanding of data structures, data flows and governance considerations.

Experience working across the full product or project lifecycle.

Excellent technical, analytical and problem-solving skills.

Strong written and verbal communication skills, with the ability to explain technical designs to a range of stakeholders.

A proactive approach with the ability to take ownership, manage changing priorities and deliver at pace.

It would also be beneficial if you have:

A technical background in areas such as solution design, software development or data architecture.

Experience developing or leveraging AI solutions, including Machine Learning, Generative AI or Agentic AI.

Knowledge of electricity settlement arrangements, systems, processes and governance.
