Job Description

Role SummaryWe are seeking a highly skilled Image Raw Data Processing Engineer to design and developlow-level raw satellite imagery data processing applications. The role involves buildingend-to-end processing pipelines from Level-0 (raw telemetry data) through Level-1 and Level-2products, performing geometric, radiometric, and atmospheric corrections, and generatingAnalysis Ready Data (ARD).The ideal candidate will have strong experience in remote sensing, image processing, andsatellite data calibration workflows.

1. Raw Data Processing (L0 → L1 → L2 → ARD)
   • Develop and maintain Level-0 data ingestion and unpacking pipelines (raw telemetry,decompression, decryption if applicable).
   • Implement Level-1 processing: Radiometric calibration, Sensor corrections, Detectornormalization, Image reconstruction
   • Implement Level-2 processing: Geometric correction & orthorectification, Atmosphericcorrection, Terrain correction, Cloud masking, Surface reflectance generation
   • Develop workflows to convert outputs into **Analysis Ready Data (ARD)** compliant withinternational standards.
2. Calibration & Correction
   • Radiometric calibration using sensor models and calibration coefficients.
   • Geometric corrections using Line of Sight(LOS) model , RPCs, GCPs, DEM integration.
   • Atmospheric correction using physics-based or model-based approaches
   • Perform BRDF corrections where applicable.
3. Algorithm Development
   • Develop and optimize image processing algorithms for multispectral, hyperspectral, orSAR data (if applicable).
   • Noise reduction, striping correction, band co-registration.
   • Implement quality metrics and validation pipelines.
