3. Summary of the role

This position sits in the Scalability Team within the Development Section of the Forecast Department. The Analyst will contribute to the development of distributed computing systems, focused on the delivery of post-processed meteorological products.

The Team contributes to a series of European projects where it researches distributed computing algorithms for processing of meteorological products, storage and handling of massive multi-petabyte meteorological data sets.

In particular, this role will involve research into the scalability and parallelism of several tools and applications that constitute the pipeline that provides flood forecasting products, including participation in the SMUFF and CEMS-Floods projects. No prior knowledge of flood forecasting is necessary.

This role will also involve participation into the EU funded project EuroExa, where it will conduct research into the use of novel architectures (such as FPGA) for the generation of products.

The successful candidate will contribute to the developments of distributed computing software for the delivery of flood forecasting products and exploration of novel hardware architectures. He or she will apply their knowledge and expertise to contribute to future developments to ensure a successful delivery of this work within the Scalability Programme.

4. Main duties and key responsibilities

  • Contributing to the development and software maintenance of distributed computing and postprocessing software stack and services at ECMWF, ensuring its quality of service and also planning for its evolution with the team and providing third-line support to its users
  • Contributing to the development of scalable flood forecasting tools and applications and their integration into the workflow including adaptations for future hardware architectures
  • Contributing to ECMWF tasks and deliverables within the Scalability Programme and related projects
  • Contributing to the analysis and monitoring of ECMWF's data processing and product generation workload and propose improvements
  • Participating in projects, including the design, implementation and maintenance of the operational applications software

5. Personal attributes

  • Excellent analytical and problem-solving skills with a proactive approach, together with an interest in identifying, investigating and solving technical problems
  • Dedication and enthusiasm to work in a small team
  • Ability to engage with staff with other technical background (i.e. environment scientists, statistics, GIS, web developers, production analyst etc…)
  • Excellent interpersonal and communication skills, listening to and respecting the views of others
  • Ability to work under pressure

6. Qualifications and experience required

Education

  • A university degree, or equivalent, in a discipline related to computer science, physics, mathematics or engineering is required. A PhD is desirable but not essential.

Experience

  • Very good experience of developing software for distributed computing and/or high-performance computing (using MPI or any other parallel processing mechanism).
  • Experience with developing and maintaining large scientific codes would be an advantage. Experience in programming with heterogeneous architectures such as ARM / GPU / FPGAs is an advantage.

Knowledge and skills (including language)

  • Very good knowledge of object-oriented programming and several years of experience developing with C/C++/Python.
  • Good knowledge of UNIX, experience developing software for UNIX systems (and/or Linux) and the use of system calls is essential.
  • Good understanding of computer science concepts (efficient algorithms and data structures) is required.
  • Experience in processing and managing large spatial data sets is an advantage.
  • Candidates must be able to work effectively in English and interviews will be conducted in English. A good knowledge of one of the C
