How We Hire

Everyone is welcome at M&S. No exceptions. It’s your background, abilities and differences that make you, uniquely you. And when you’re part of M&S, that individuality has the potential to make waves.

About the role

This section tells you all you need to know about the position and its responsibilities, outlining everything we hope to see in a successful candidate.

All the details

We're changing the way we do things, and putting industry leading innovation at the heart of how we operate; we need a stellar engineering team to make it happen. You'll be joining one of the most iconic brands in the UK on its most exciting cycle yet. We're more integrated and product led in our tech teams than ever before: learning, changing, and adapting constantly, with millions of people benefiting from your work every single day.

You’ll be joining the M&S Platform team as a Software Engineering Manager. Our mission is to streamline development at M&S for 1000+ engineers and 30+ applications - covering both our customer-facing and colleague-facing applications.

You will manage the team building the SRE function. You will support the team and help direct the technical vision for how we will build reusable pipelines, tooling, build plugins and frameworks that our many apps will harness to boost the developer experience, while contributing code every step of the way.

We want to make M&S one of the best places for software development, target the latest tooling and enable our engineers to focus on building the best user experience so that they don’t get held up by common engineering and continuous integration problems.

What You'll Do

Being accountable for engineering excellence within your teams, from behaviours to operations, from technical direction to solution in production and from skills and growth to reputation.

Cultivating self-management and accountability throughout the team via leadership, clear sense of purpose and thoughtful talent management.

Lead alignment with the overarching technical strategy and working with the wider Technology organisation to craft it.

Act as a platform owner, apply accurate product thinking to what is being built with a view to enable and empower as much as possible the digital product(s) that it supports through data and customer centricity, driving the related partner management.

Collaborate with the entire engineering leadership, to make us think strategically, to ensure maximum alignment and to maintain a healthy ability to “think big” within their teams.

Line management of supporting Staff and Senior Engineers, as well as driving recruitment and retention within the team.

Act as custodian of OKR’s within your hub.

Supports our engineering communities to drive bar raising and strategic alignment, by creating the space and time within teams for the agenda of these communities to be progressed efficiently.

When vendors are involved, the SEM is positioned as the key technical partner. They own it as a vital part of their platform with the same level of reliability and satisfaction as the in-house capabilities they build and run.

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.

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.

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.
