About the role

  • Deliver meaningful features end-to-end — design, build, test, deploy, and evolve backend-focused services with a strong sense of ownership and quality.
  • Build modern, scalable systems — develop primarily in Java, Kotlin, Golang, or Node.js, collaborating with frontend engineers and contributing where needed to React/TypeScript applications.
  • Shape architecture and technical direction — apply Domain-Driven Design, Test-Driven Development, microservice and event-driven patterns to solve complex problems and raise the bar across the team.
  • Lead cloud-native development — design and operate services on AWS, using containers, orchestration platforms, and serverless patterns to build resilient, future-proof solutions.
  • Design data and system behaviour at scale — model data across NoSQL and relational systems, ensuring performance, reliability, and secure operation in distributed environments.
  • Strengthen delivery and operational excellence — improve CI/CD pipelines, support production systems, and continuously refine engineering practices for long-term sustainability.

Requirements

  • Solid senior experience (5+ years) building backend systems in cloud-native, distributed environments.
  • Strong ownership mindset — you’re comfortable taking a feature from idea to production and standing behind your decisions.
  • Architectural judgement — you know when and how to apply DDD, TDD, microservices, and event-driven design pragmatically.
  • Hands-on cloud and DevOps experience — particularly with AWS, containerisation, CI/CD, and modern deployment models.
  • Experience leveraging AI-assisted development tools and methods to enhance productivity, code quality, and system design.
  • Clear, thoughtful communication and a willingness to mentor others.
Benefits
  • Meaningful mission — Your software helps protect homes, businesses, and communities around the world, contributing to solutions people rely on every day.
  • Innovation at scale — Work with modern cloud platforms, event-driven architectures, and evolving technologies in a global environment.
  • Autonomy and trust — You’re trusted to make decisions, influence design, and own your work from idea to impact.
  • Growth and development — Learn continuously, deepen your technical expertise, and explore opportunities across teams and borders.
  • Work–life balance — Flexible working, hybrid options, and a culture that supports sustainable performance.
