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 Dev Ops and CI/CD practices, including automated testing, infrastructure as code, and deployment pipelines.
