Staff 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 Staff Software Engineer to provide technical leadership across our Contact Centre. This is a hands-on, high-leverage engineering role: you will solve the most complex technical problems, shape direction across teams and evolve the services, integrations and customer experiences built around Contact Centre as a Service (CCaaS) platforms such as Azure, Google, Zendesk and Twilio.

You will work closely with engineering, Product, Architecture, Data, Security and Customer Service colleagues to turn customer and colleague needs into reliable, scalable and measurable technology. This includes customer FAQ and self-service experiences, colleague tooling and responsible AI automation. The role is primarily focused on backend engineering in Java, while providing technical direction for frontend experiences 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

Set and communicate technical direction for Contact Centre technology, aligning near-term delivery with a coherent longer-term architecture.
Design, build and operate secure, resilient, observable services and platforms that can evolve as the business changes.
Stay hands-on with production-quality code, technical discovery, design decisions, reviews and complex problem solving.
Lead the design of distributed systems, APIs, integrations and event-driven workflows where appropriate.
Define robust integration patterns for Zendesk, Twilio and other CCaaS capabilities across telephony, messaging, case management and customer data.

Who you are:

Significant experience designing, developing and operating production software at scale.
Strong understanding of software engineering principles, distributed systems and modern delivery practices.
Deep backend engineering experience with Java and its associated frameworks, architecture patterns and testing practices.
Experience designing integrations with third-party SaaS platforms; knowledge of Azure, Google, Zendesk, Twilio or another CCaaS platform is particularly relevant.
Experience leading technical direction across more than one team or product area, with the influence to bring people with you.

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.

Meet the Team

A group of colleagues gathered around a table, smiling and discussing work with laptops open in a modern office setting.

Being an in-person business

We're at our best when we're close to customers, and for many of us at M&S, that means working in store every day.

To stay close to customers, our support teams are in the office three days a week as we believe that skills are developed through collaboration, and that spending time together makes us more creative and connected. It also means we can solve problems as soon as they arise, learn and grow as a team, build trust, and get closer to our colleagues.

Halford Head of Technical Program Management

Being in third-party brands, working on things M&S hasn’t done before… that plays to my sweet spot. I’ve worked in many organisations throughout my career, and it’s rare to see such cause and effect in your work. The way we’re structured means you’re encouraged to solve problems and you have the autonomy to make progress quickly.

I think all engineers just love solving puzzles and problems. At M&S, we’re constantly learning new things, whether it’s mastering Swift UI or understanding how customers interact with technology. But this is also a business that listens to engineers and values what we bring to the table. That’s different, believe me.

At M&S, we have Data Scientists, Analysts, and Technical Product Managers, who all share a genuine passion for harnessing data to improve people’s lives. And we’re in a unique position where we can actually help many different kinds of people, from our customers to our colleagues in store and in our support centre.
