I have been at the Met Office since graduating and have been able to work my way from a foundation scientist to a manager. I enjoy working with customers on the application of science, helping them operate more safely and efficiently and enabling them to be more resilient to the weather both now and in the future. I get to see how the work of the team is directly having impact and benefit to industry and society.
Senior Scientific Software Engineer
There is a great variety of work here, sometimes I can be applying new science to one of our models, improving some of our internal tools, reviewing code, helping someone get the most out of their development plan, or attending a talk to learn new skills. Sometimes I work with older code cleaning it up, so it works better and is more future-proof. It’s always satisfying to see other people working with my improved code.
Anna Whitford
Scientific Consultant
Coming from an academic background I wanted to be able to develop new research approaches, but I also wanted a change towards being more impact-focused, where the science I produced would be both useful and used right away. My work is supporting customers to better understand the impact of climate change on their business, with the added benefit of gaining experience on a wide range of projects - there is always something new to learn!
Emily Wallace
Science Fellow, Weather and Climate Extremes and Impacts Team
The Weather and Climate Extremes and Impacts Team was formed in response to multiple extreme events in the UK. Our customers are dealing with the impacts of severe weather and are more routinely asking questions that blur the lines between what would have traditionally been thought of separately as weather services and climate services. The work we do is critical in our changing world as we bring together teams to provide seamless services to help people stay safe.
