Full Stack Developer
We are looking for a Full Stack Developer to help us build and improve SiteView using React, Java and AWS. If you enjoy working across front-end and back-end development, solving technical challenges and collaborating with an experienced team, we'd like to meet you!
About the 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.
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.
