Senior Satellite Image Processing Engineer

Own the end-to-end data product chain for Twinspector's dual-satellite constellation: from raw detector output, through onboard processing, to ground L1A/L1B generation, radiometric and geometric calibration, and delivery-ready imagery. You will work daily with hardware and software partners, internal ground processing and product teams, and geospatial/ML engineers who consume the imagery products.

What you'll do

• Own the definition and documentation of the full data processing chain from L0 through onboard processing to ground L1A/L1B generation.
• Drive decisions on which processing steps run onboard vs. on the ground, balancing bandwidth constraints, data quality, and storage budgets.
• Define sensor output packet format, onboard data handling format, downlink packaging, and final image product specification.
• Own the in-orbit calibration programme: DSNU/PRNU correction table management, side-slither maneuver planning, lunar drift monitoring, and vicarious calibration campaigns.
• Develop and maintain the ground L1B processing chain: flat-field correction, radiometric calibration, geometric sensor modelling, and RPC generation.
• Lead technical interface discussions with hardware partners on onboard processing constraints and ICDs.
• Maintain the AWS-based cloud stack and drive adoption of cloud-native geospatial standards (COG, Zarr, STAC).

What you'll need

• Strong working knowledge of optical satellite data processing from raw to analysis-ready (L0→L1B).
• Radiometric and geometric calibration for space-borne optical instruments.
• Able to hold the system-level picture while engaging with low-level technical details.
• Background in space systems engineering, remote sensing, or a closely related field.
• Python for data analysis, processing workflows, and automation.
• Comfortable in multi-stakeholder, multi-supplier environments where interfaces are still being defined.

Nice to have

• Experience with TDI pushbroom sensor calibration.
• In-orbit calibration campaign planning or execution.
• Experience with stereo satellite missions or photogrammetry.
• Familiarity with VHR commercial satellite data (Pleiades, WorldView, SuperView).

What they offer

• Flexible working hours and hybrid work model.
• Collaborative and learning environment with frequent internal workshops and knowledge sharing.
• Office in Berlin Kreuzberg with free fruit, nuts and drinks.
• Urban Sports membership, BVG subsidy, and corporate pension program.
• Employee stock option program eligibility.
