Job description

Senior Solution Architect - Enterprise Applications (SAP)

• Architect a six-workstream ERP transformation end to end
• Lead clean-core SAP design across S/4HANA, BTP and MDG
• 12-month contract, Melbourne hybrid, direct ARB influence

Senior Solution Architect – Enterprise Applications

We’re looking for a Senior Solution Architect with real functional depth in Retail, Supply Chain or Finance.

This is not an integration-only or SAP module role.

It’s for an enterprise-first architect who happens to have deep SAP experience.

You’ll sit across six workstreams as the architect who keeps the program coherent: guiding solution design, simplifying the integration landscape, uplifting master data governance and holding the line on the Target Architecture.

What you’ll be doing

• Leading end-to-end solution design across Finance, Supply Chain, Retail Platforms, HR and Corporate Applications
• Championing clean-core principles across S/4HANA, BTP and MDG, keeping customisation to a minimum and using BTP or SaaS for extensibility
• Rationalising integrations toward API-first, event-driven patterns and away from point-to-point
• Defining master data ownership across product, supplier, customer and finance domains
• Aligning designs to identity, security and access models (Entra ID, SAP IAS/IPS, ServiceNow provisioning)
• Taking solutions and option analysis to the Architecture Review Board and influencing senior stakeholders
• Bringing structure and clarity to a multi-vendor, regulated environment, and challenging vendors and SIs where needed

What you’ll bring

• 10+ years in enterprise solution architecture
• Strong functional architecture background in Retail, Supply Chain or Finance
• Hands-on S/4HANA architecture at scale, plus BTP and MDG; SuccessFactors is a bonus
• Experience leading architecture on one or more large ERP or transformation programs, ideally alongside global SIs
• A solid grasp of clean-core, RISE and cloud deployment models
• Commercial awareness covering TCO, licensing and vendor leverage
• A calm, structured communication style and strong written and visual artefacts

Experience in retail, distribution or other regulated, high-volume environments is highly regarded.

Why this role matters

This architect is central to keeping the program aligned, scalable, compliant and future-ready. It’s a rare chance to shape a transformation that touches every part of the business, and to leave behind a cleaner, simpler architecture that you found.

If you’re a senior architect who enjoys bringing order to complex programs, I’d love to hear from you.
