We are building a high-fidelity software platform for space. 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.

What You Will Actually Do
- Own the end-to-end software architecture and be the final arbiter of all design decisions across every layer
- Write and review production-quality numerical simulation code in a compiled systems language
- Define and enforce interface contracts between the simulation core, the data layer, the API backend, and the desktop client




- Design the HPC job lifecycle — submission, monitoring, interactive and batch execution modes, command channels, and event streaming to connected clients
- Make technology selection decisions with explicit written rationale that survives team turnover
- Write detailed design documents that junior engineers implement from — unambiguous, complete, and correct
- Mentor engineers across the stack; conduct reviews with the depth of someone who wrote the code themselves

Requirements:
Orbital Mechanics and Astrodynamics
- Solid working knowledge of analytical orbit propagation — not just calling a library, but understanding what it computes, its accuracy envelope, and where it breaks down
- Hands-on experience with numerical orbit propagation using adaptive step integrators, with full perturbation models: atmospheric drag, higher-order gravity, solar radiation pressure, third-body effects
- Familiar
