Key about your role

As a Full Stack Developer at Keylane UK, you help develop SiteView, our digital claims platform. SiteView enables insurers to automate workflows, manage digital site visits and connect customers, claims teams and suppliers throughout the claims process. Your work helps make that experience easier to manage and follow. Keylane

You contribute throughout the development lifecycle, from prototyping and developing new features to testing and deployment. On the front end, you work with JavaScript, React, Redux Saga, HTML and CSS. On the back end, you use Java/J2EE, Maven, jOOQ and MySQL, with Docker and AWS forming part of the wider development environment.

Alongside building new functionality, you improve what is already there. You investigate application issues, resolve bugs and identify performance bottlenecks. You follow sound development practices and take responsibility for writing code that is secure, maintainable and reliable.

You work closely with fellow developers and colleagues across the business to understand requirements and translate them into practical solutions. Whether you are exploring a new feature or troubleshooting an existing one, you combine technical curiosity with attention to detail.

Key about your team

You join a small team of experienced developers working on SiteView. Together, you build secure, scalable SaaS software for enterprise customers.

Collaboration is an important part of the role. You discuss technical challenges, share knowledge and work with colleagues from other departments. You are comfortable progressing your own work independently, while knowing when to involve others and work through a problem together.

Requirements

It’s a plus if you have experience with AWS services such as EC2, RDS, SES or SWF; React Native; Jenkins; Python; or Bash. Familiarity with GitHub, IntelliJ and macOS is also useful.

Using AI

You can explain how you have applied them to activities such as understanding code, developing features, writing tests or troubleshooting;
  • You understand where these tools can support the development process and where human judgement is essential. You provide clear requirements and context, and recognise when an output needs further investigation;
  • You critically assess, test and debug AI-generated code and suggestions. You remain responsible for the correctness, security and maintainability of everything you deliver.
