Software Development Engineer, Leo Data Science Platform

Overview As a Software Development Engineer on the VirtSat Platform, you will build and scale the cloud layer that controls virtual satellites, gateways, and antennas. You’ll own the simulation service control plane and APIs that provision and manage cloud-based satellite assets, ensuring high availability and low latency. You collaborate with subsystem teams to define plugin contracts and health checks, enabling self-service operations for a multi-tenant constellation. This role combines cloud, distributed systems, and cyber-physical engineering to accelerate Leo’s mission of global connectivity.
