Job description

Lithium3 are looking for an experienced Solution Architect (applications and not infrastructure) to support a project focused on the Microsoft ecosystem, including Microsoft 365, Azure/Entra, Power Platform and ideally Copilot.

This role will focus on application architecture, solution design and application integration, rather than infrastructure architecture.

£600 per day. 6 months initially. Once per week in the office.

We are looking for someone who can translate business requirements into robust, scalable and secure application solutions, working across enterprise applications, SaaS platforms, business systems and integrations.

You will work closely with business stakeholders, delivery teams, technical specialists and third-party suppliers to define solution designs, ensure applications work effectively together, and support the delivery of solutions that meet business and technical requirements.

• Define and maintain application solution architectures across the Microsoft ecosystem, including M365, Azure/Entra, Power Platform and Copilot-related solutions.
• Translate business requirements and processes into application solution designs, architecture documentation and technical specifications.
• Design application integrations, considering APIs, data flows, interfaces, identity, authentication, SSO and dependencies between systems.
• Assess existing applications and business systems to identify opportunities for integration, optimisation, automation and modernisation.
• Ensure application solutions align with enterprise architecture standards, security policies, governance requirements and business objectives.
• Provide architectural guidance on Microsoft 365, Power Platform and SaaS application capabilities, including appropriate use of standard functionality versus bespoke development.
• Support the design and governance of AI-enabled applications and Copilot solutions, considering permissions, information protection, data residency, responsible AI and access controls.
• Work with project managers, business analysts, developers, vendors and systems integrators to ensure solutions are technically sound and deliverable.
• Review supplier proposals, solution designs and technical recommendations, ensuring they meet requirements and align with the wider application architecture.
• Support application testing, release planning and production readiness, including SIT, UAT, deployment dependencies and technical acceptance criteria.
• Define application support and service transition requirements, including operational ownership, support models, monitoring and BAU handover.
• Communicate architectural decisions, risks, dependencies and recommendations clearly to both technical and non-technical stakeholders.
