All the details
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 Foods Product 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 how we ingest, model, and distribute food-related data across M&S.
The team owns the platform that supports supplier systems, price and promotion information, product lifecycle and master data, and critical supply-chain data flows. We sit at a unique intersection, providing high-quality, timely data to our colleagues and partners while enabling internal teams to build on a robust food data 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
- Build and evolve reliable data services – design and develop scalable, high-performance pipelines and APIs in Java and Micronaut, integrating with event-streaming platforms such as Kafka. Your work will ensure accurate, timely information reaches downstream systems and business users.
- Own features end-to-end – take responsibility for everything from design through development, testing, deployment, and production monitoring. You will balance delivery speed with sustainability, ensuring the platform remains maintainable over time.
- Shape the technical direction of our Food Platform – contribute to the platform architecture, promoting clean data contracts, well-defined schemas, and event models. Help craft solutions that balance data quality, integration reliability, and developer usability, while considering cost-versus-performance trade-offs at scale.
- Champion engineering excellence – write clean, maintainable, well-tested code and help establish best practices across multiple teams. You will encourage a continuous improvement culture through code reviews, pair programming, and high-quality documentation.
- Drive operational excellence and observability – share responsibility for the reliability of our data integrations. Use observability tools such as Dynatrace to design for monitoring and alerting and participate in our support rota to ensure supply-chain and pricing data remains accurate and available.
- Collaborate widely – work closely with Product Managers, cross-functional engineering teams, Supply-Chain, and Commercial teams to solve real business problems in thoughtful and innovative ways. Cross-functional decision-making and breaking down information silos are essential to shortening time to value.
- Mentor and support colleagues – provide coaching and feedback to more junior engineers. Help grow our community of practice by sharing knowledge and fostering an inclusive environment.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Who You Are
- Experienced in data-intensive distributed systems – 5+ years building and scaling services that handle large datasets, ideally serving millions of records or transactions. You understand both batch and event-driven processing and can design systems that remain resilient at scale.
- Skilled in JVM languages – proficient in one or more JVM-based languages such as Java, ideally working with Micronaut, and comfortable writing clean, maintainable code.
- DevOps and CI/CD practitioner – experienced in designing and running CI/CD pipelines (for example, GitHub Actions) and driving improvements in developer productivity and release automation. Familiarity with Infrastructure as Code (Terraform) helps automate repeatable infrastructure changes.
- Cloud and data platform savvy – comfortable working in cloud environments (preferably Azure) and familiar with modern data processing and integration tools. Experience with Kafka for event streaming, SFTP for batch data ingestion, relational and NoSQL databases (MongoDB), and SaaS integrations for product lifecycle and pricing is highly valued. Exposure to containerization and orchestration technologies such as Docker and Kubernetes, and infrastructure automation with Terraform, is a plus.
- Data modelling and integration expert – understand domain-driven design, data contracts, and schema evolution. You care about data quality and integrity and know how to integrate with third-party systems without excessive customization.
- Balance strategic thinking with pragmatic delivery – you can weigh long-term architectural goals against immediate business needs, are sensitive to commercial impacts, and thrive in high-autonomy teams.
- Security and quality minded – experience using modern security and static-analysis tools such as Snyk and Semgrep to identify vulnerabilities and enforce coding standards. A commitment to secure coding practices and compliance is essential.
- Curious about AI-assisted development – open to leveraging AI tools like GitHub Copilot, and others to enhance productivity and accelerate learning while maintaining code quality.
- Full-stack awareness – while primarily a backend/data engineering role, understanding of front-end technologies like React/Angular enables effective collaboration across the stack.
