Pilot Compliance Platform for UK Construction

Solution Architect – Multi-Tenant SaaS Platform We are looking for an experienced Solution Architect to help us define and independently review the technical architecture for a new workforce, site-access and H&S compliance SaaS platform being prepared for a pilot. The platform will need to support multiple tenants, hundreds of sites, thousands of workers, mobile/offline use, complex permissions, RAMS/document processing, AI integration, audit trails and future integrations with access control/CCTV systems. We are looking for someone with strong experience in: Multi-tenant SaaS architecture Microsoft Azure or equivalent enterprise cloud architecture Identity, authentication, RBAC and tenant isolation PostgreSQL / scalable data architecture APIs and enterprise integrations Secure application architecture Mobile/PWA and offline design AI/LLM or document-processing integration Architecture documentation and technical assurance The initial requirement is architecture and technical assurance rather than coding. You should be comfortable producing the architecture independently and allowing a separate development team to implement it. Please reply with: brief background/CV; examples of SaaS platforms you have personally architected; Azure/cloud experience; multi-tenant and security experience; availability; day rate or fixed-price approach. We are particularly interested in architects who can explain complex technical issues clearly to a non-technical product owner.
