Job Description

SAP Technical Architect

Role Overview

We are looking for an experienced SAP Technical Architect to own the end-to-end technical architecture across SAP S/4HANA and the wider SAP landscape (on premise and cloud).

The role will be accountable for defining and governing the overall technical design, including:

• SAP S/4HANA core platform (and/or ECC where still in scope)
• SAP BTP and integration (CPI, APIs, eventing)
• Extensions and custom development (ABAP / CAP / RAP / Fiori)
• Interfaces to non SAP systems (HR, CRM, legacy, data/analytics platforms)
• Security, performance, resilience and DevOps/automation

You will work closely with enterprise architects, functional leads, developers, basis/infra teams and third parties to ensure that the SAP solution is scalable, secure, supportable and aligned to best practice. You should be comfortable leading technical design workshops, challenging implementation approaches, and communicating architecture clearly to both technical teams and business stakeholders.

Requirements 1. Overall SAP Technical Architecture

Own the end-to-end technical architecture across the SAP estate (S/4HANA, BTP, integrations, satellites).

Define target state and transition state architectures for SAP programmes (Greenfield, Brownfield, carve outs, upgrades, cloud migrations).

Ensure the design aligns with:

• Security and compliance requirements
• Performance, scalability and availability goals

Maintain architectural artefacts (high level designs, interface catalogues, system landscapes, integration diagrams, data flow diagrams).

2. Solution & Technical Design Governance

Lead technical design workshops with SAP functional teams and development teams.

Review and approve technical designs for:

• RICEFW objects (Reports, Interfaces, Conversions, Enhancements, Forms, Workflows)
• Integrations and APIs
• Extensions on SAP BTP (e.g. CAP/RAP, side by side extensions)
• Fiori/UI5 applications and custom apps

Define and enforce development standards and guidelines:

Chair or actively participate in the Design Authority / Technical Design Board, making sure all changes are architecturally sound and consistent.

Design integration patterns between SAP and non SAP systems:

• SAP BTP Integration Suite / CPI

Produce and maintain:

• Interface catalogues and mappings
• Error handling and monitoring models
• Security and authentication patterns (OAuth, SAML, certificates etc.)

Work with integration and data teams to ensure loosely coupled, scalable and resilient integrations that support future change.

4. Platform, Basis & Cloud Infrastructure

Work with Basis and cloud platform teams to define:

• System landscape (dev / test / pre prod / prod) and refresh strategy
• Sizing, performance and capacity planning for S/4HANA and related systems
• HA/DR strategy, backup and restore, and failover scenarios

Contribute to the design of cloud hosting for SAP:

• SAP on Azure/AWS/Private Cloud
• Network, connectivity and security zones
• Use of managed services and platform services

Support technical upgrades and migrations (e.g. ECC to S/4HANA, on prem to cloud, DB migrations).

5. Security, Compliance & Performance

Define security architecture for SAP:

• Roles and authorisations strategy
• Segregation of duties (SoD) considerations
• Identity and access management (SSO, Azure AD or equivalent)

Ensure compliance with:

• Corporate security policies
• Regulatory requirements (e.g. GDPR, audit trails, logging)

Support performance tuning:

• Work with Basis and dev teams on performance bottlenecks
• Ensure good design choices around data volumes, indexing, queries and batch jobs.

6. Delivery Support & Technical Leadership

Provide hands on technical leadership to SAP development teams and partners:

• Mentor developers and technical consultants
• Support solutioning and effort estimates for new requirements
• Provide guidance on when to use standard vs custom vs BTP extensions
• Participate in sprint planning and backlog refinement (for Agile projects)
• Resolve technical design issues and unblock delivery teams
• Ensure non functional requirements are built into the backlog and delivered (performance, resilience, security, supportability).

Contribute to testing and cutover:

• Validate technical readiness for SIT/UAT
• Ensure monitoring, logs and technical operations are in place for go live
• Support cutover planning for complex technical changes.

7. Stakeholder Management & Communication

Act as the primary technical point of contact for SAP with:
