SAP Technical Architect
Senior Technical Architect – Hybrid (Product / Platform)
The Opportunity
Can you make a cloud-native product and an SAP core work as one coherent system?
That's the problem this role exists to solve. You'll architect the seam between a modern, AI-enabled product built on Node.js and an SAP S/4HANA Private Cloud platform landscape, making sure public cloud innovation and the SAP core evolve together rather than drifting apart. The split is roughly 70% cloud-native product architecture, 30% SAP platform architecture, and you'll carry real design authority through the Architecture Board rather than just advising from the sidelines.
The Role
Design microservices architectures on Node.js using API-first and event-driven patterns
Define service boundaries, data flows, multi-tenant capability, and non-functional design: performance, scalability, resilience, cost
Architect AI integration within the product, including LLM, RAG and agentic patterns, with a focus on performance and cost optimisation
Design the integration layer between cloud-native products and SAP S/4HANA Private Cloud, using OData, REST, SAP Business Events and Event Mesh
Provide architectural guidance for S/4HANA Private Cloud extensions and side-by-side scenarios, enforcing clean core principles
Own design governance: HLD, SDD and TDD creation, technical review and sign-off in the Architecture Board
The Company
You'll be joining a business running a genuinely hybrid technology landscape: a modern, AI-enabled product sitting alongside an established SAP S/4HANA Private Cloud platform. Rather than being boxed into one side of that world, you'll shape architecture across both at once, working at the point where cloud-native engineering and enterprise SAP practice actually meet. The engagement runs as an initial 6-month contract, with an onsite cadence that steps down over time: two to three days a week in the first month, then fortnightly, then monthly. That structure gives you a proper embedding period up front, then real flexibility once you're established.
What You'll Need
Several years' experience as an architect in cloud-native environments
Strong expertise in Node.js, microservices and API architectures
Strong understanding of event-driven systems, with experience integrating AI into software products
Cloud architecture experience, including containers, orchestration and scaling
Working knowledge of SAP S/4HANA Private Cloud and clean core extension patterns
A proven track record integrating cloud-native applications with an ERP core
