I work on a team that builds space mission design software: https://ai-solutions.com/freeflyer-astrodynamic-software/ https://ai-solutions.com/freeflyer-astrodynamic-software/ There's a lot of fun problems involved related to computational geometry, 3D rendering, numerical methods, parser/compiler design, and astrodynamics ("space math").
