Within ASPECT, ECMWF co-develops, operationalizes and promotes workflows that transform the climate data over different time-scales (from months and seasons to decades) into information for users in sectors important for society such as agriculture, finance, energy and also for the EU Mission on adaptation.
As Scientific Applications Developer you will be responsible for designing, developing and running workflows. The workflows, co-developed with ASPECT users, are performed on the underpinning climate data and are delivered as a set of python packages, jupyter notebooks and java script web-applications, including user guidance and documentation. The applications will be based on the C3S infrastructure (Climate and Atmosphere Data Store, CADS) using ECMWF Earthkit tools ( The applications will be initially developed employing existing C3S data sets and later will make use of newly generated data from simulations run in ASPECT. Where possible, the computations will be executed within the infrastructure in a distributed, service-oriented architecture. Subject to scoping analysis of C3S, a set of workflows running on climate predictions will be extended and prototypes of workflows will be delivered for adoption in the C3S operational environment.

The contract duration is 3 years up to 31 Dec 2026, with the possibility of extensions.
