Job description

We are seeking a highly skilled Integration Engineer to join a major national digital services programme, based out of Doha, Qatar, for an initial 6 month contract.

A senior architect who owns how the platform's mobile app, its integration layer, and its backend connections fit together, and who runs the process by which the programme makes and records architectural and technical decisions.

Key skills we're looking for:

• Experience: 10+ years in solution or enterprise architecture roles, including substantial hands‑on experience with mobile application architecture and with integration platforms such as MuleSoft.
• Mobile architecture: Hands‑on understanding of native iOS/Android app architecture.
• Integration architecture: MuleSoft as an API/integration gateway.
• Cloud platform literacy: working knowledge of Azure (AKS/Kubernetes, APIM, Key Vault, Redis, Azure Database for MySQL, Azure DevOps).
• Identity and access: understanding of national digital-identity login patterns and enterprise identity (Entra ID/OIDC/OAuth).
• Security and data-protection awareness: understanding of what it means to keep personal data secure and compliant when it moves across a mobile app, an integration layer, and more than ten separate backend systems.
• Experience working across multiple organisations with differing technical maturity and priorities.
• Certifications (an advantage, not required): MuleSoft Certified Architect or Developer; a cloud architecture certification such as Microsoft Certified: Azure Solutions Architect Expert; a recognised architecture framework certification (e.g. TOGAF) is a plus given the governance emphasis of this role.
