• A practical, user‑focused approach to solving problems, with curiosity, creativity and enthusiasm for learning.


• A degree in computer science, information technology or a related subject, or equivalent practical experience.

It would be an advantage, but is not essential, if you have:

• Experience with headless CMS platforms, composable architectures or decoupled front‑end applications.


• Strong commercial experience with .NET and C#.


• Experience building applications with Vue or React.


• Knowledge of Microsoft Azure services and cloud‑based application development.


• Experience with relational databases such as Microsoft SQL Server or MySQL.


• Experience creating automated tests and working with continuous integration and deployment pipelines.


• An understanding of web security, performance optimisation and recognised accessibility standards.


• Experience working in an Agile delivery environment.

Most importantly, you will enjoy working with others, experimenting with ideas and creating digital experiences that make complicated tasks feel simple. If you want to develop your skills, build technology with a real social purpose and see how great applications can contribute to saving lives, we would love to hear from you.

Our purpose is simple: to save lives at sea. Our RNLI lifesavers are ready to launch to the rescue, 24 hours a day, every day. Our lifeboat crews and lifeguards need a dedicated, professional, and talented team behind them. This is your chance to join that team and help save lives every day.
