Date Mon, 16 Oct 2017 17:53:49 +0000

We are looking to further enhance our team by adding a
Hyper-spectral Sounding Products Generation Prototyping Specification and 
Validation Engineer
You will be based initially for 2 years at our client’s headquarters in 
Darmstadt, Germany. Extension of a further year may be possible. In this large 
European Agency you will find an excellent and modern working environment with 
challenging tasks and responsibilities.
Your Tasks Include:
The Key Person will be part of the HSIRL2 team. The Key Person shall especially 
contribute to the specifications documentation and prototyping of the IASI-NG 
principal components (referred to as L1D in EPS-SG context) and L2 products 
generation functions and to the support of the operational software 
implementation during the initial development phase of the Payload Data 
Acquisition and Processing. Support to the preparation and completion of the 
commissioning of IASI/Metop-C is also expected.

The tasks of the Key Person will typically include:
•       Analysis of similarities and specificities to the IASI and IASI-NG 
processing within the EPS and EPS-SG contexts and the required products, with 
the aim to maximize algorithm re-use.
•       Maintenance and evolution of the IASI-NG products generation 
specification documents, taking into account the above identified commonalities 
and specificities. 
•       Maintenance and evolution of the documentation including new science 
resulting from internal developments or external studies or contributions.
•       Contribution to the review and analysis of specification documents for 
the input data to the IASI-NG processing chain, e.g. IASI L1c, MWS L1b etc.
•       Contribute to clarifications and answers to issues raised during the 
reviews of IASI- NG L1D and L2 documentations; evolve the IASI-NG products 
generation specification documents taking the review outcome into account.
•       Support the porting and re-use of IASI processing software in the 
context of EPS-SG for IASI-NG, including the preparation and documentation of 
S/W packages, test and verification data.
•       Prototype functions of the IASI-NG L1D and L2 processing chain.
•       Adapt and evolve the existing IASI L2 operational processor to form an 
IASI-NG prototype, e.g. make it ready to ingest IASI-NG and MWS L1 synthetic 
test data.
•       Contribution to the harmonization of the IASI and IASI-NG processors.
•       Integration and verification of external software deliveries in the 
prototype processor 
•       Software anomaly fixing
•       Code optimization 
•       Development and documentation of prototype software and test procedures
•       Generation of test data
•       Statistical analysis and visualization of hyper-spectral infrared 
principal components and Level 2 products 
•       Support L2 monitoring facilities and interpretation 
•       Contribution to validation reports for IASI operational and IASI-NG 
prototype products.

Your Profile:

The Key Person shall have a University degree (or equivalent) in a relevant 
discipline such as computer science, mathematics, physics, astrophysics, 
meteorology or remote sensing.
The Key Person shall have at least three years of experience in the field of 
scientific computing. Specifically, the Key Person shall have experience and 
skills in:
•       Numerical algorithms; 
•       Development and testing of complex scientific software; 
•       Documentation of complex scientific software; 
•       Generation and documentation of test data and test procedures; 
•       Handling and processing of big amounts of data; 
•       NetCDF format and using associated libraries; 
•       Object oriented techniques for scientific computing; 
•       Concurrent S/W development in a team and Software tools for revision 
•       Very good skills in C++; 
•       Advanced use of data analysis and visualization with tools like IDL or 
Matlab; preferably with satellite data.

Experience in some of the following areas is expected and will be an advantage: 
•       Inverse problems 
•       Principal component analysis 
•       Further mathematical modelling techniques (non-linear optimization, 
regression, neural networks, Kalman filters, etc.) 
•       Familiarity with satellite data, preferably from IASI or other 
hyper-spectral infrared instruments
•       Use of radiative transfer models 
•       Retrieval of atmospheric parameters from infrared and/or microwave 
•       Software testing 
•       Validation and visualization of satellite products 
•       Software libraries for numerical linear algebra and similar subroutines 
•       Experience with further programming relevant languages and tools such 
as Perl, Python, Java, etc. 
•       Multi-threads programming

The Key Person shall have good interpersonal skills. He/she shall have the 
ability to write clear and concise scientific reports as well as clear and 
exhaustive scientific S/W documentation; in English.

The Key Person shall be willing and able to learn about new topics as required 
for the tasks.

The Key Person shall be able to conduct all activities in an orderly and 
structured manner, shall be able to work calmly and correctly under stress. The 
ability to pay attention to details is mandatory, especially in the context of 
thorough software verification and software specifications documentation before 

The Key Person must be able to work with the minimum of supervision.
The official languages are English and French. The working language for the 
position is English and therefore Key Persons must be able to work effectively 
in this language and have a working knowledge of the other.
