Solutions Architect (Logistics)

Solution Architect – Logistics / WMS Modernisation (Contract)

Duration: 6–12 months

Location: UK (Onsite collaboration required – Holborn & Coventry as needed)

Engagement: Via leading consultancy supporting a major UK supermarket

The Opportunity

This is a hands-on architecture role sitting at the centre of a complex transformation programme within a major UK retailer.

You’ll be brought in to untangle legacy mainframe dependencies and drive the transition toward a modern, scalable warehouse and logistics ecosystem. It’s not a clean slate. It’s a high‑stakes environment where operational continuity matters just as much as technical ambition.

Expect ambiguity, competing priorities, and plenty of stakeholders with opinions.

Scope of the Role

• Own and define end‑to‑end solution architecture across warehouse and logistics systems
• Lead mainframe modernisation and decommissioning efforts, from assessment through to cutover
• Ensure alignment and integration across ERP, TMS, OMS, and automation platforms
• Translate business and operational requirements into pragmatic, deliverable solution designs
• Govern architecture through design reviews, risk management, and technical assurance
• Support delivery teams with issue resolution, impact analysis, and change control
• Communicate clearly with senior stakeholders, cutting through noise and focusing on outcomes

What They Need You To Bring

• Strong track record in mainframe modernisation / decommissioning programmes
• Re‑platforming
• Data archival and retention
• Deep understanding of warehouse operations and logistics processes
• Hands‑on experience with WMS platforms:
• Blue Yonder and/or
• Solid grasp of modern architecture principles:
• Microservices
• API‑led and event‑driven architectures
• Experience analysing legacy systems, data structures, and dependencies
• Proven ability to govern data migration, validation, and cutover activities
• Comfortable working across conceptual, logical, and physical architecture layers
• Strong stakeholder management. You’ll need to influence, not just design

Environment & Ways of Working

• Onshore presence required for key workshops and planning sessions (Holborn & Coventry)
• Working within a multi‑vendor, cross‑functional delivery model
• Tools: Jira, Confluence, Miro (standard, but you’d be surprised how many struggle here)
• Prior experience within retail or grocery supply chains
• Exposure to automation systems within warehouse environments
• Broader understanding of data engineering and platform modernisation
