Software Engineer

Join us as a Senior Software Engineer in the Event Fabric team, where you will play a key role in designing, building, and evolving a core enterprise platform that enables event‑driven, cell‑based architecture across the organisation.

This role goes beyond application development. You will work on foundational platform capabilities that enable teams to reliably publish, consume, govern, and operate events at scale. You will bring well‑developed hands‑on engineering skills alongside a platform mindset, contributing to both technical delivery and engineering direction, while mentoring others and promoting modern engineering standards.

To be successful as a Senior Software Engineer, you should have experience with:

• Designing, building, and operating Event Fabric capabilities that support asynchronous, loosely‑coupled integration across distributed systems, including the delivery of production‑grade platform components from proof‑of‑concept through to enterprise adoption.
• Contributing to event standards, patterns, and best practices, enabling teams across the organisation to build confidently on the platform.
• Making considered design choices that balance scalability, resilience, security, and developer experience.
• Close collaboration with product, architecture, and engineering teams to align platform capabilities with business and regulatory needs, alongside supporting and mentoring engineers and promoting high standards of code quality, testing, and operational readiness.
• Experience with Spring Boot and building production services using modern Java frameworks, together with a solid understanding of DevOps and CI/CD practices, including automated testing, infrastructure as code, and deployment pipelines.

Some other highly valued skills may include:

• Hands‑on Java engineering experience, building high‑quality, maintainable, and well‑tested systems, including the design and delivery of distributed systems using event‑driven and asynchronous communication patterns.
• Practical experience with microservices and API design, with a clear understanding of service boundaries, integration contracts, and non‑functional requirements such as resilience, scalability, observability, and failure handling.
• Experience working with event‑streaming or messaging platforms (e.g. Kafka or equivalent), including concepts such as topics, partitions, schemas, consumer groups, and delivery semantics.
• Experience modelling data in NoSQL technologies (e.g. MongoDB) within distributed, eventually consistent systems.
• Experience deploying and running services on cloud platforms (such as AWS), with awareness of security, networking, and cost considerations.

You may be assessed on the key critical skills relevant for success in role, such as risk and controls, change and transformation, business acumen strategic thinking and digital and technology, as well as job-specific technical skills.

This role will be based in Knutsford or Northampton.
