We’re looking for a Senior Software Engineer to play a pivotal role in evolving M&S’s Order Management platform. This team provides the critical software capabilities that power order fulfilment across the business, ensuring customers receive a seamless experience from checkout through to delivery, amendments, cancellations, and returns.

Your “customers” are product teams, engineers, fulfilment stakeholders, and ultimately millions of M&S customers — and your mission is to make them faster, more effective, and more confident through scalable systems, resilient integrations, and exceptional engineering practices.

This is a role for an engineer who is excited by solving complex fulfilment challenges, modernising enterprise systems, and building reliable software that supports one of the UK's largest retail operations.

Your responsibilities

Your key accountabilities will include:

• Design, build, and evolve order management capabilities that support seamless customer fulfilment journeys across checkout, fulfilment, returns, amendments, and cancellations.
• Own features end-to-end, taking responsibility for solution design, development, testing, deployment, and production support.
• Help shape the technical direction of the Order Management platform, driving improvements in architecture, integration patterns, automation, reliability, and security.
• Drive operational excellence by designing systems with observability, monitoring, resilience, and supportability at their core.
• Use tools such as Dynatrace to improve platform visibility, monitoring, and alerting capabilities.
• Collaborate closely with Product Managers, Engineering teams, and Fulfilment stakeholders to solve complex business challenges and accelerate delivery outcomes.

Required skills

• A senior software engineer with deep backend engineering experience and a proven track record of delivering reliable, scalable systems in complex enterprise environments.
• Strong Knowledge with IBM Sterling Order Management and the challenges associated with large-scale ecommerce fulfilment operations.
• Strong Java engineer with experience designing and developing enterprise services, APIs, and integrations across distributed systems.
• Experienced in CI/CD practices, observability, production support, and operational excellence.
• Comfortable designing systems with resilience, recoverability, monitoring, and supportability in mind.
• A collaborative engineer who enjoys working across disciplines, raising standards, and helping teams continuously improve.
