Solenix is specialized in the provision of highquality software engineering, technical consulting and operations services in the aerospace domain. This vacancy note concerns an onsite consulting position at EUMETSAT in Darmstadt, Germany. Optical Sensor Calibration Engineer Senior 1620153 Job Description We are looking for a Senior level Optical Sensor Calibration Engineer to support the calibration of the Ocean and Land Colour Imager OLCI and Sea and Land Surface Temperature Radiometer SLSTR instruments on the Sentinel3 mission, which EUMETSAT operates on behalf of the European Commission. Hence, the focus will be to provide an indepth understanding of the instruments calibration and characterisation in orbit. The calibration data and instrument performance will be analysed using existing tools and by developing inhouse tools for instrument calibration as well as vicarious and intercalibration to adjust and monitor the operational calibration systems. You shall support the Calibration Team of INRC competence area, in close collaboration with the Ocean Colour and Surface Temperature Radiometry teams in the Marine Applications competence area, whose activities the consultant shall primarily support. Your tasks will typically include scientific analysis of the radiometric and spectral calibration of Ll data from OLCI and SLSTR analysing results of prelaunch and inorbit calibration systems and characterisation data , including solar diffusers, straylight, nonlinearity, SNR, polarisation sensitivity spacecraft manoeuvres performed during or after commissioning developing indepth knowledge of the instruments operational processing chain applying the calibration monitoring tools to OLCI and SLSTR, which will include a combination of pseudoinvariant calibration sites Rayleigh scattering over the sea lunar calibration deep convective clouds intercalibration against collocated hyperspectral sounder observations developing specific components of the calibration monitoring tools to handle Sentinel3 data analysing results of these tools to provide information on these sensors performance performing comparisons with other instruments, such as A VHRR, VIIRS, MODIS to gain understanding of the performance of OLCI and SLSTR using GEOCAL tool developed by ESA to monitor geometric performance, providing recommendations to implement changes to the operational procedures and processing chains to improve the instruments calibration working with the team responsible for generating L2 products for these instruments to assess and improve the instruments calibration writing and reviewing documentation describing the instruments calibration and aspects oftheir Ll processing. Required Skills and Experience A university degree or equivalent in Physics, Remote Sensing, Instrument engineering, or similar At least 5 years experience in the processing of satellite data to generate calibrated Ll datasets in the visible, near andor thermal infrared At least 5 years experience in L 1 calibrationvalidation Recognised expertise in the calibration of optical sensors both prelaunch and on orbit Demonstrate a good working knowledge of statistical techniques and understanding of the concepts of calibration and Good knowledge of radiative transfer in the solar andor infrared spectral ranges and experience in applying them for surface andor atmospheric applications Proven experience in the use of data analysis tools, such as MatlabIDL, scripting languages, such as PerlPython and highlevel programming, such as CCFORTRAN on a LinuxUnix environment, and an aptitude to learn further programming languages as required Experience in the implementation of calibration algorithms Very good communication skills both verbal and written are an important aspect of this role both between teams within EUMETSA T and with Industry and ESA Desirable Skills and Experience Knowledge and practical experience with the calibration of similar optical sensors, such as MERIS, MODIS, OLCI, AATSR or A VHRR. Experience of working in an operational satellite environment. Experience of image analysis. Experience with a range of different data formats used in satellite remote sensing. Experience with Software build environments and version control tools. Work Location Darmstadt, Germany Dates Application Deadline 17 October 2016 Start of Work January 2017 Important Notes Before applying to this position, please read the page Notes to Applicants on the Solenix website under Career.
