Your future duties and responsibilities
In this role, you will lead the design and implementation of secure, scalable cloud and hybrid infrastructure solutions that meet complex business challenges.

This role allows you to take ownership of cloud architecture direction while being supported by a collaborative network of experts committed to achieving excellence together.
In addition to shaping new cloud solutions, you will play a pivotal role in the delivery and operational support of existing ("in-situ") cloud estates across client environments - ensuring seamless continuity, reliability, and compliance across live operations.

Transition & Knowledge Sharing: Support smooth transitions between design, delivery, and operations, ensuring strong documentation, knowledge transfer, and mentoring of delivery teams.

Lead & Innovate: Drive the design of AWS, Azure, and Oracle Cloud architectures to meet evolving client needs.
Develop & Deliver: Translate complex business and technical requirements into robust, scalable cloud and hybrid infrastructure designs.
Optimise & Automate: Champion Infrastructure-as-Code (IaC), CI/CD, and automation to improve efficiency and quality.
Collaborate & Influence: Work with stakeholders to define cloud strategies, assess risks, and ensure alignment with business goals.
Evaluate & Recommend: Assess new technologies, leveraging tools like Azure Recommendations and cloud vendor rebate systems.
Mentor & Support: Guide team members, fostering technical growth and sharing best practices across CGI.
Plan & Propose: Contribute to pre-sales activity, estimating infrastructure costs, producing proposals, and supporting bid responses.
