Senior Software Engineer- Customer Support

About M&S

Marks & Spencer is transforming how it operates as a digital-first, engineering-led retailer. Our Digital & Tech teams build the services, platforms and experiences used by millions of customers and thousands of colleagues across stores, websites, apps and support functions.

We are ambitious about the future of retail. We aim to raise standards, do the right thing and create inclusive teams where people can bring their whole selves to work.

About the role

We are looking for a backend-focused Senior Software Engineer to design, build and operate the services and experiences that power our Contact Centre. You will work as a strong individual contributor within a multidisciplinary team, integrating Contact Centre as a Service (CCaaS) platforms such as Azure, Google, Zendesk and Twilio and helping customers find answers through effective FAQ and self-service experiences.

You will collaborate with engineers, Product, Architecture, Data, Security and Customer Service stakeholders. You will take ownership from discovery through delivery and live operation, balancing customer value, maintainability, security, performance and speed. The role is primarily back‑end engineering in Java, with opportunities to contribute to customer and colleague interfaces built with React and Next.js.

Due to high interest, this role may close earlier than advertised. We recommend applying as soon as possible.

What you'll do

• Design, develop, test, deploy and support reliable software across the full delivery lifecycle.
• Translate product and business needs into clear technical approaches and incremental delivery plans.
• Contribute to the design of APIs, services, integrations, data flows and event-driven solutions.
• Build and maintain integrations with Zendesk, Twilio and other CCaaS capabilities, including messaging, telephony, case management and customer context.
• Develop customer self-service and FAQ capabilities that provide accurate, accessible answers and a smooth hand-off to Contact Centre colleagues when further help is needed.

Who you are

• Proven experience delivering and operating robust software in a professional engineering environment.
• Strong knowledge of software engineering principles, design patterns and maintainable code.
• Experience developing backend systems, APIs and integrations, or equivalent depth in the relevant engineering discipline.
• Strong backend development experience with Java and its associated frameworks and testing practices.
• Experience integrating third-party SaaS platforms; knowledge of Zendesk, Twilio or another CCaaS platform is particularly relevant.
• Good understanding of automated testing, continuous integration and continuous delivery.

What's in it for you

• 20% colleague discount across M&S products and selected third-party brands after probation.
• Competitive holiday entitlement, with the option to buy additional days.
• Discretionary bonus schemes linked to personal and business performance.
• Defined contribution pension scheme and life assurance.
• Tailored induction, training and development opportunities.
• Discounts and wellbeing support through the M&S Choices portal.
• Family-friendly parental, adoption and neonatal policies.
• Wellbeing support, including virtual GP access and support for you and your family.
• One paid charity volunteering day each year.

Benefits and eligibility are subject to the applicable M&S terms and policies.
