Geospatial Data Scientist

Develop geospatial and remote-sensing methods that turn imagery and spatial data into reliable analytical products. You’ll work in Python on change detection, object detection, segmentation, and spatial and temporal analysis. Your methods will span classical machine learning, statistical and image analysis, and deep learning architectures such as Vision Transformers (ViTs) and U-Nets, taking the approaches that prove useful from exploration through evaluation into repeatable platform capabilities.

The work includes open satellite time series and commercial optical, thermal, and SAR imagery. You’ll help choose appropriate data and methods, establish what the results can support, and work with engineers to make them available to analysts inside Sentinel., * The opportunity to establish new analytical capabilities within an existing intelligence platform.

• A mix of scientific depth and practical delivery, with direct feedback from GEOINT specialists and analysts.
• Close collaboration with data engineers and software engineers to bring useful methods into production.
• Remote-first work in Germany with regular team sessions in Berlin and occasional sessions in Frankfurt and Munich.
• 30 days of vacation, equipment and learning support, and room to develop expertise across remote sensing and geospatial analysis.

• Strong Python and scientific computing skills, using tools such as NumPy, pandas, SciPy, xarray, GeoPandas, and Rasterio/GDAL.
• Practical machine-learning experience with scikit-learn and PyTorch or an equivalent framework, plus TorchGeo or related geospatial deep learning packages, including training, evaluation, and adapting existing models.
• A solid understanding of remote-sensing fundamentals: spatial, spectral, radiometric, and temporal resolution; coordinate systems; image alignment; and data-quality limitations.
• Experience with satellite image analysis and at least one relevant task such as change detection, segmentation, object detection, or land-cover classification.
• Sound statistical judgment around sampling, spatial autocorrelation, data leakage, class imbalance, uncertainty, and generalization to new places and acquisition conditions.
• An engineering-minded approach to research: versioned code and data, reproducible experiments, tests, and clear explanations of how a method performs and fails.
• Clear communication in English with both technical colleagues and domain specialists. Eligible to work in Germany.

Nice-to-haves

• Experience working with thermal infrared imagery, processing and analysing SAR data, or combining observations from multiple sensors. Deep experience in one modality is valuable.
• A PhD in geoinformatics, remote sensing, Earth observation, or a related field.
• Experience with geospatial foundation models: fine-tuning models such as Prithvi or TerraMind, or using AlphaEarth Foundations embeddings for downstream analysis. Ability to evaluate whether these approaches improve on task-specific models with the available imagery and labels.
• Experience scaling geospatial analysis with Dask, Apache Spark/Sedona, or Zarr.
• Experience deploying and optimising GPU inference with PyTorch/CUDA, ONNX Runtime with TensorRT, or NVIDIA Triton Inference Server, including batching image tiles and managing GPU memory and throughput.
• Spatial SQL with DuckDB or PostGIS, STAC-based data discovery, and exploratory work in QGIS or geemap; producing COG and GeoParquet outputs for downstream GIS use.
• Experience working with commercial imagery from providers such as Airbus, Satellogic, SatVu, or ICEYE.
• Experience working in defence and intelligence environments or on related projects.
• Strong interest and practical ability in agentic software development: using coding agents to plan, implement, test, and review software, and keeping up with rapidly evolving tools, techniques, and trends.

• Develop change-detection workflows, including Sentinel-2 time series, and distinguish meaningful change from seasonality, cloud and shadow effects, acquisition differences, and registration errors.
• Build and evaluate object-detection, segmentation, and classification methods for satellite imagery, using statistical techniques, classical image processing, and machine learning where appropriate. Evaluate state-of-the-art deep learning approaches pragmatically against simpler baselines, weighing accuracy, label requirements, generalization, inference cost, and real production viability.
• Assess the suitability of different sensors, resolutions, acquisition conditions, and processing levels for each use case. Extend methods across optical, multispectral, thermal, and SAR data as requirements develop.
• Design preprocessing and feature extraction with data engineers: quality masking, compositing, co-registration, normalization, spectral indices, and sensor-specific corrections.
• Combine raster outputs with vector and temporal data for spatial statistics, zonal analysis, anomaly detection, and comparison across areas and observation periods.
• Build or source reference datasets and evaluation protocols. Use spatially and temporally separated validation, measure false positives and missed detections, and examine performance across regions and sensors.
• Deliver traceable results with source references, timestamps, confidence or uncertainty measures, and documented limitations. Help analysts understand when a result needs closer review.
• Package tested Python methods for repeatable batch processing or inference. Work with data and platform engineers on runtime, memory, monitoring, and integration into Sentinel workflows.

Orcrist builds secure data intelligence software for defense, law enforcement, and enterprise teams. Our Sentinel platform combines data integration, AI-assisted analysis, and operational workflows. The GEOINT team is extending it with geospatial data services, remote-sensing capabilities, and a web-based common operational picture.
