This team provides the critical software capabilities that power online payments across the business, enabling millions of customers to complete purchases securely, reliably, and seamlessly across all M&S digital channels.

Your "customers" are product teams, engineers, business stakeholders, and ultimately millions of M&S customers - and your mission is to make them faster, more effective, and more confident through scalable services, resilient integrations, and exceptional engineering practices.

This is a role for an engineer who is excited by building high-volume transactional systems, solving complex payment challenges, and modernising technology platforms that sit at the heart of M&S's online growth ambitions.

About the Team

You will join the Payments team, helping to modernise and evolve critical payment capabilities.

What You'll Do

Your key accountabilities will include:

• Design, build, and evolve payment services and capabilities that enable seamless customer transactions across M&S digital platforms.
• Develop resilient backend services, APIs, and integrations that support millions of customer payment journeys every year.
• Own features end-to-end, taking responsibility for solution design, development, testing, deployment, and production support.
• Help shape the technical direction of the Payments platform, balancing performance, scalability, resilience, security, and cost through modern engineering practices.
• Champion engineering excellence through clean, maintainable, and well-tested code, helping establish best practices across engineering teams.
• Drive operational excellence by designing systems with observability, monitoring, resilience, and supportability at their core.
• Utilise tools such as Dynatrace to improve platform visibility, monitoring, alerting, and service reliability.
• A senior backend software engineer with deep experience designing and delivering scalable, resilient systems in complex enterprise environments.
• Strong Java engineering expertise with experience building enterprise services, APIs, and integrations across distributed systems.
• Knowledge in designing systems that serve large customer populations while maintaining high availability, performance, and security.
• Work with ecommerce platforms, payment services, or highly transactional systems is advantageous.
• Passionate about software quality, testing, maintainability, and engineering best practices.
• Strong understanding of CI/CD, observability, production support, and operational excellence.

Here are some of the benefits we offer that make working for M&S just that little bit more special...

• 20% colleague discount across M&S products and selected third-party brands.
• Competitive holiday entitlement with the potential to buy extra holiday days.
• Discretionary bonus schemes awarded based on personal and business performance.
• A generous Defined Contribution Pension Scheme and Life Assurance.
• A tailored induction and extensive learning and development opportunities.
• Amazing perks and discounts via the M&S Choices platform, including GymSave and the opportunity to become an M&S Shareholder.
