Summary
👤
Senior🎓
Top SchoolMatthias Ellmer is a senior software engineer specializing in high-performance C++ and Python solutions for Earth observation and satellite gravimetry, with 11 years of experience spanning academia and NASA JPL to Planet’s Orbits R&D. He has architected and optimized large-scale MPI-parallel workflows that cut runtimes by up to 98%, enabled higher-resolution mass-change products, and lowered noise floors in gravity field solutions through data-driven noise modeling. Skilled in end-to-end pipeline automation, auditable workflows, and web dashboards, he combines deep geodesy and covariance analysis expertise with practical software engineering to turn petabyte-scale sensor data into actionable spatial insights. A PhD-trained geodesist who grew university HPC capacity sixfold and mentors early-career researchers, Matthias brings a blend of scientific rigor and production-grade engineering to satellite mission data challenges.
