Software Developer (.NET/AWS)

Our platform is evolving towards a modern AWS-native architecture, making extensive use of serverless technologies, microservices and event-driven systems to deliver highly scalable and reliable solutions.

You will help design and develop scalable distributed systems and shared services that support multiple products used by insurers, suppliers, police forces and supporting organisations across the UK and internationally.

You will work across the full software development lifecycle, from architecture and design through to deployment and operational support, collaborating with engineers, product managers and stakeholders to deliver high-quality solutions.

This role is ideal for developers who enjoy building scalable cloud services, solving complex technical problems, and continuously improving how software is delivered.

What You'll Be Building

Our platform is built around shared cloud services running on AWS, supporting multiple SaaS products across the insurance ecosystem.

You will work with technologies such as:

AWS Lambda, Step Functions and API Gateway
