Job Description:

As part of the M&S Software Engineering team, you’ll be joining a well-loved historic brand, working on solutions that serve millions of loyal customers and thousands of colleagues! With ethical values that run right through the company’s core and technology leaders that truly understand software engineers and engineering, it’s an exciting time as we’re redefining ourselves into a digital first and engineering-led organisation, with the quality of our engineering team being a key differentiator.

About the Role

The M&S Identity team is looking for a Senior Software Engineer to join our dynamic team. You will provide technical expertise, ship thoughtful solutions, and operate with excellence. Creative, curious, and fearless, you will be an integral part of our empowered, self-managing domain engineering team, pushing the boundaries of our Identity Platform.

The team is responsible for the M&S Identity Platform, managing authentication journeys for both customers and colleagues. We sit at a unique intersection, delivering seamless authentication experiences for customers while enabling internal teams to build on a robust Identity Platform.

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. Join our community of engineers to help build a modern digital ecosystem, work with cutting-edge technologies, and do the best work of your career.

What you'll do

1. Build and evolve secure, scalable, and high-performance authentication experiences for millions of M&S customers and colleagues.
2. Take end-to-end ownership of features — from design and development through testing, deployment, and monitoring in production.
3. Contribute to the technical direction of the Identity Platform and help shape solutions that balance customer experience, security, and developer usability.
4. Write clean, maintainable, well-tested code, and champion engineering best practices in your team.
5. Take shared responsibility for the operational excellence of the Identity Platform, including participating in our 24-hour support rota.
6. Collaborate closely with Product Managers, Designers, and Engineers to solve real user problems in thoughtful and innovative ways.
7. Actively participate in code reviews, pair programming, technical discussions and creating high quality documentation to share knowledge and continuously improve as a team.
8. Mentor and support more junior engineers through coaching and feedback.

Who you are

1. 5+ years of experience building and scaling distributed systems, ideally serving millions of users.
2. Good knowledge in one or more JVM-based languages (ideally Kotlin with Micronaut).
3. Proven experience in DevOps practices, including running and operating what you build.
4. Experience designing CI/CD pipelines and driving improvements in developer productivity.
5. Comfortable working in cloud environments (preferably Azure).
6. Experience with identity standards like OAuth 2.0 and OpenID Connect is a strong plus.
7. You balance long-term thinking with pragmatic delivery, and thrive in high-autonomy teams.

What’s in it for you

Being a part of M&S is exactly that – becoming a part and playing your part. We’re an inclusive, dynamic, exciting, and always evolving business built on core values.

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

1. 20% Colleague discount on most things from furniture, fashion, and food.
2. A first-class welcome to M&S with a tailored induction and a wide range of training schemes to help with your learning and development.
3. Attractive annual bonus, based on company performance and personal objectives.
4. Competitive holiday entitlement with the potential to buy extra holiday days!
5. Amazing perks and discounts via our M&S Choices website.
6. Charity Volunteer Day – A paid day away from work to support your chosen charity.
7. A very generous Defined Contribution Pension Scheme and Life Assurance.
8. Access to a fantastic range of wellbeing support.
