About the Role

The M&S Online Fulfilment area is looking for a Staff Software Engineer to join our Promising team. You will provide technical expertise, lead the design and delivery of robust solutions, and operate with excellence. Creative, curious and pragmatic, you will lead the modernisation of our order management software to provide a seamless customer experience and enable M&S’s online growth ambitions through a scalable, reliable, secure and cost-effective system. The Promising team is on a multi-year journey to build the platforms and services that will provide accurate delivery details to our customers. Our ambition is to provide accurate, real-time delivery and collection options so customers can get the products they want, when and where they want them. In this role, you will play a key part in driving our ambition to create a best-in-class software engineering team, environment and culture.

Responsibilities

Build and evolve order management and promising capabilities – design and enhance resilient services, APIs and integrations that support accurate delivery promises, inventory visibility and fulfilment decisions across digital and retail channels.
Own features end-to-end – take responsibility for design, development, testing, deployment and production support of our promising platform.
Shape the technical direction of our Promising Platform – help evolve the services, integrations and decisioning that power how we source, promise and fulfil orders across stores, distribution centres, suppliers and digital channels.
Champion engineering excellence – write clean, maintainable, well-tested code and help establish best practices across multiple teams.
Drive operational excellence and observability – share responsibility for the reliability of our data integrations. Use observability tools such as Dynatrace to design for monitoring and alerting and participate in our support rota to ensure supply-chain and pricing data remains accurate and available.
Collaborate widely – work closely with Product Managers, cross functional engineering teams and other Fulfilment teams to solve real business problems in thoughtful and innovative ways.
Mentor and support colleagues – provide coaching and feedback to more junior engineers. Help grow our community of practice by sharing knowledge and fostering an inclusive environment.

Requirements

A strong technical leader – you bring deep backend engineering experience and a track record of shaping reliable, scalable systems in complex enterprise environments.
Experienced in the IBM Sterling order management product suite and the fulfilment domain – you understand the technical and operational challenges involved in inventory visibility, promising, sourcing and fulfilment, with experience implementing IBM Sterling products to tackle these challenges.
Strong in Java and enterprise integration – you are confident building services, APIs and integrations that operate reliably across a varied systems landscape, and you write clean, maintainable code with a strong focus on long-term sustainability.
Operationally excellent – you care about CI/CD, observability, production support and release quality, and you design systems with resilience, recoverability and supportability in mind.
Pragmatic and commercially aware – you balance technical ambition with delivery, understand the impact of engineering choices on customer experience and operational outcomes, and make sensible trade-offs in service of the wider business.
Collaborative and improvement-focused – you enjoy working across disciplines, raising engineering standards and helping teams adopt better tools, practices and ways of working.
