• Event-driven integrations
• CI/CD pipelines and automated deployments
• Scalable SaaS systems used across the UK insurance market

The work you contribute to will help insurers process claims faster, improve decision making and deliver better outcomes for customers.

What we're looking for

We’re particularly interested in developers who enjoy building scalable cloud services and shared platform capabilities, and who are comfortable working with modern distributed architectures on AWS.

You should be someone who enjoys solving problems, learning new technologies, and contributing to the evolution of engineering practices within the team.

What you'll get

• Opportunity to work with modern cloud-native architecture on AWS
• Exposure to microservices, serverless platforms and distributed systems
• Collaboration with experienced engineers across the UK and globally
• The chance to contribute to platform-level services used across multiple products
• Opportunities to develop new technical skills and grow your engineering career
