Principal Software Engineer - Space Simulation Platform

We are building a high-fidelity software platform for space situational awareness — one that supports both live operational use and operator training from a single unified codebase. The system spans a high-performance physics simulation engine, a scientific data pipeline, a REST and event-streaming backend, and a native desktop client with 3D rendering.

This is not an architecture-only role. The Principal Software Engineer is the final technical authority and is expected to be hands-on across all layers — writing simulation code, designing data interfaces, making HPC infrastructure decisions, and being the person who can sit down, open an editor, and solve the hard problem anywhere in the system.

You will own the architecture, make and document the decisions that stick, and be directly accountable for correct implementation across the team.

Key Responsibilities:

• Own the end-to-end software architecture and be the final arbi...
