Your role is to contribute to the development, maintenance and evolution of our core data encoding and decoding capabilities. You will be part of a dynamic team of scientific software engineers who contribute to key activities at the company. In this role, you will focus on software, algorithms and workflows for handling meteorological, climate and geoscientific data formats. There will be a strong emphasis on the WMO formats GRIB and BUFR, as well as other widely used scientific formats such as NetCDF.

This work will include leading the development of key libraries and tools, notably the open-source package ecCodes, and contributing to software packages that handle meteorological data. You will help ensure that the company and its Member and Co-operating States continue to benefit from robust, efficient and sustainable software for handling operational and research data across a range of meteorological and environmental workflows.

You will contribute to both the reliability of production-quality software and the longer-term evolution of the company’s data-handling capabilities, helping to meet the needs of internal users, external partners, and the wider meteorological community. You will work closely with colleagues across software engineering, data governance and scientific development teams, and also with technical representatives of other organisations such as our Member States’ meteorological services.

Your responsibilities include:

• Develop, maintain and enhance the company software libraries and tools for encoding and decoding meteorological and environmental data.
