SAP Solution Architect

Location: Milton Keynes, hybrid (2-3 days on site per week) | Duration: 12 months | IR35: Outside |

Realtime Recruitment is looking for a principal-level ERP Solution Architect with deep SAP technical expertise and cloud-native Azure integration experience to join a major national programme. This is a true greenfield site: there is no legacy estate to work around, and the programme is now moving into low-level design, so you’ll be shaping the solution at the point where the important decisions get made.

This is a client-side role. An implementation partner is delivering the SAP solution and the finance leads own the finance processes. You will be the independent technical voice alongside both, making sure what gets designed is coherent, secure, well integrated and fit to run.

What you’ll be doing

• Defining and maintaining the end-to-end technical architecture for the SAP solution: landscape, environments, integration, data, identity, security, resilience, performance, monitoring and supportability
• Steering the solution through low-level design, making sure detailed designs hold true to the agreed architecture
• Aligning the SAP design with enterprise architecture principles, Azure Integration Services, cloud-native integration patterns, the data platform and connected core systems
• Reviewing and challenging the implementation partner’s technical designs, assumptions, dependencies, extensions and non-standard components
• Assessing the technical impact of proposed configuration, extensions, third‑party products, custom development and manual workarounds
• Defining and assuring interface architecture, data contracts, mappings, integration controls, error handling, observability and technical reconciliation
• Working with Cyber, Enterprise Architecture and Technology Operations on access, security roles, segregation of duties, data protection, environments, release controls and transition to service
• Giving technical input to design authority, quality gates, testing, migration, cutover and readiness decisions, flagging risks and recommending actions
• Translating finance requirements into technical implications and confirming the partner’s design addresses them

What the role isn’t

You won’t be designing finance processes or making accounting decisions, and you won’t be configuring or building. You own the client-side technical architecture view and advise programme governance on technical fitness, risk and alignment.

What you’ll bring

• Principal‑level SAP solution architecture experience across complex, integrated enterprise implementations
• Cloud‑native integration experience with Azure Integration Services (such as API Management, Logic Apps, Service Bus and Event Grid), ideally integrating SAP with Azure and enterprise data platforms
• Strong technical knowledge of SAP S/4HANA landscapes, SAP BTP and SAP Integration Suite, plus interfaces, environments, identity, security, data, non‑functional requirements and service transition
• Experience on greenfield programmes, particularly through low‑level design
• Experience acting as client‑side design authority and independently challenging a systems integration partner
• The ability to turn business and finance requirements into technical impacts and architecture decisions
• A background in high‑volume, regulated or operationally critical environments
