Job Description
What's the role?
We are seeking a Senior Infrastructure Solution Architect to lead the design and delivery of major infrastructure solutions. You'll work closely with stakeholders to turn business needs into clear technical designs and support those designs through to implementation. You'll play a critical role in shaping infrastructure solutions that enable business change.

* Document assumptions, constraints, and architectural trade-offs in a clear and structured way
* Apply business context, delivery constraints, and risk posture to ensure solutions are fit for purpose
* Provide accurate estimates for infrastructure solutions, including CAPEX and OPEX
* Present solution designs to governance forums and clearly explain rationale and trade-offs
* Communicate technical decisions clearly to both technical and non-technical stakeholders
* Support delivery teams through build, integration, testing, and transition to production
What do I need?
You bring design experience across modern infrastructure stacks, including cloud, midrange, network, storage, and security. You understand where each technology fits, how to align it to architectural standards, and how to guide teams through delivery.
* Public cloud platforms including AWS and Azure (certification desirable)
